Plasma Cutter Thickness Ranges:

2011-05-30T00:02:00.000-07:00

Plasma Cutting machines that can use both manual and mechanized tasks generally have a lower thickness rating for mechanized cutting rather than manual. This is for some reasons.

Initial and end the cut on resources close to the maximum thickness correctly needs some operator method that is simple for a human operator but hard or not possible to program into a machine. Hence a lower rating for acceptable cuts.

Mechanized plasma cutting needs sharp in many cases rather than edge starts. A machine usually cannot pierce successfully as thick as it can cut.

Customers using plasma cutting equipment in an automated set up would normally find the cut speeds on the thickest resources too slow to be satisfactory for mechanized process.

The Advantages MIG Welding:

2011-05-26T00:27:00.000-07:00

There are a lot of advantages that MIG welding has over other welding types. Following are some of the advantages,

• First of all it is quite easy to study MIG welding. You can turn into pretty good at excellence welds in a small quantity of time. You can purchase a decent MIG welder for under $500. Also, a lot of these machines will be able to run off of a normal 110v outlet. Cleanup from a welding session is minimal.
• The next advantage is speed. Since a solid nonstop wire is used there is no require to change rods. There is also no require for chipping the weld, as the sum of slag is reduced. Quality welds can be created faster than most other welding types. You must be able to achieve a higher output of work compared to most other types of welding.
• The removal of flux in MIG welding will help prevent slag defects in the weld.
• The shield gas helps guards the arc which eliminates the need to regularly replace the electrode. This will also help prevent weld splash.
• It is easier to weld thinner materials.
• Can be used on a broad selection of metals, including stainless steel, mild steel and aluminum.
• The welding procedure can be either manual or automated.

So as you can see MIG welding has a lot of advantages that create it accessible to the beginner.

Tips for Welding Supplies:

2011-05-23T00:31:00.000-07:00

Explosive Welding - Advantages and Disadvantages:

2011-05-19T00:00:00.000-07:00

Explosive Welding Advantages:

(i) Ease of the process.
(ii) Extremely big surface can be bonded.
(iii) Welds can be created on heat-treated metals with no affecting their microstructures.
(iv) This foils can be bonded to heavier plates.
(v) Broad range of thicknesses can be explosively clad jointly.
(vi) Explosive bonds have a solid condition joint that is free from warmth affected zone.
(vii) Good explosive bonds typically contain strength equal to or greater than that of the weaker of the two metals joined.
(viii) Lack of porosity, phase changes and structural changes communicate improved mechanical properties to the joints.

Explosive welding Disadvantages:

(i) In industrial areas the use of explosives will be harshly limited by the noise and earth vibrations caused by explosion.
(ii) The rules relating to the storage of explosives and the difficulty of preventing them from falling into unauthorized hands can well prove to be the major obstruction to the use of explosive welding.
(iii) A limitation to explosive cladding is concerned with the fragility of the alloys. Metals to be bonded by this procedure must possess some ductility and some crash resistance. Metals harder than about 50 RC are tremendously hard to weld.
(iv) Metal thicknesses bigger than 62 mm of every alloy cannot be joined simply and need high explosive loads.
(v) Resources such as beryllium, tungsten, boron, glass and ceramics are not usually processed by explosive welding.

Forge Welding:

2011-05-16T23:48:00.000-07:00

Forge welding is the oldest known welding process which has been practiced for centuries. The procedure is still used even though its application is limited because of the certain complexity connected with it.

Metals which can be Forge Welded:
Wrought iron and low carbon steels (with C content less than 0.2%) can be acceptable forge welded. Forge welding can be accepted out with metal thicknesses up to about 30 mm.

Surface Preparation:
Surfaces of the metal parts to be forge welded are prepared by upsetting the pieces at the ends. A variety of edge preparations necessary to be carried out previous to forge welding.

Procedure for Forge welding:
The parts to be forge welded are given an edge (or joint) preparation as clarified above. Then, the parts are heated to over l000°C until they are plastic. In this state, the parts are positioned on the anvil end to end and are hammered jointly, either using a power hammer or physically, until they form a solid structure of metal.

In forge welding process, a very significant requirement is that during heating the absorption of sulphur from the coke of the fire and scaling of the pieces (to be welded) ought to be prevented or that if scale is created, the hammering should be completed in such a way as to squeeze this out of the joint and allow metal to metal contact. Besides being combined by blows from a hammer, the work¬ pieces may also be welded by being rolled, drawn or squeezed together.

Different materials are spot welded together?

2011-05-12T23:30:00.000-07:00

The immediate reply is yes, but it may be neither easy nor advisable in certain cases if brittle structures are produced by the different metals mixing in the molten nugget.

In exacting austenitic stainless steel and carbon steel is not generally spot welded jointly since the resulting nugget arrangement risks being hard and brittle, though it can be studied and modified using the Schaeffer diagram and particularly conceived warmth treating cycles.

Materials having widely dissimilar properties need that a warmth balance be achieved by compensation. The additional conductive material, electrically and thermally, have to be heated extra as it provides fewer resistive warmth, and the warmth is lost more easily by conduction.

An ordinary method uses an electrode of smaller face diameter and superior resistivity facing the additional conductive material, or by inserting a foil of poorly conductive material among them.

Concerning the number of sheets weldable with a single nugget, usual practice advices not more than three layers, although four sheets are infrequently spot welded jointly. In any case the ratio of the thickest to the thinnest sheet should not go beyond three.

EBW (Electron Beam Welding) Repair of a Discarded Casting:

2011-05-09T23:22:00.002-07:00

Regular welding would not be a satisfactory solution. But Electron Beam Welding a spare bushing in place, while expensive, may recover the cost previously invested in the finished and discarded part.

By welding in place a spare sleeve the procedure has the possible:

• of exactly focusing the beam on top of the joint, in spite of the distance,
• of introducing the small amount of warmth, avoiding spoil to mechanical properties and preventing intolerable bend,
• of creating a slim and deep, exactly located weld seam,
• of avoiding the require for frequent warmth treatment,
• of permitting thorough non destructive testing to be eligible the repair,
• of being performed within the shortest turnaround time limiting the delay in delivering a substitute part.

Aluminum Castings repaired:

2011-05-05T00:01:00.000-07:00

Aluminum Alloy castings scrapped in the foundry since of surface defects and lack of dimensional integrity can be recovered by welding apart from if they present massive porosity.

Gas tungsten arc welding (GTAW) with high frequency stabilized Alternating Current is usually used to fix sound castings. Inclusions are supposed to be disallowed by taking care to avoid touching the surface with the pure tungsten electrode.

Argon with or without helium can be used as a shield. Helium helps produce a hotter arc if essential. To arrange for welding one should remove defects, particularly cracks, by dry chipping with a rounded tool or by hand milling, to get a smooth area. One ought to by no means attempt to weld on the original casting outside rough surface with no first removing the oxidized coating.

Removal of oil and grease is performed using steam degreasing or clean solvents. Use of acid etch is not suggested. If impregnation was applied, it should be removed previous to welding. A spotless stainless steel wire brush should be used to clean thick oxide layers just earlier than welding.

Filler material alloy is regularly the same as that of the casting. Preheating is wanted only in outstanding cases to conquer difficulties.

On correctly prepared surfaces of sound castings, with oxide coatings thoroughly cleaned, one should be able to weld as with no trouble as on wrought alloys. It would be fine practice to look for cracks in the weld by using penetrant inspection.
Radiographic check may be necessary by contract in sure cases.

If the original castings are to be warmth treated, also the fixed ones should go after the same procedure. Weld repairing of heat treated casting would impair their mechanical properties.

The possibility of repair of aluminum alloy castings that were previously heat treated and machined is doubtful since of stresses and deformations likely to develop during welding.

Tips for Overhead Tig Welding:

2011-05-02T23:54:00.000-07:00

Following are the major pointers for learn how to tig welds overhead using the walk the cup method...

1. Enlarge the electrode far sufficient to have the correct torch angle.

2. Maintain the electrode sharp and if it gets crapped up, sharpen it or exchange to a sharp one.

3. A flex head welding torch assists for getting the torch body far sufficient away from the hot metal.

4. Maintain a tight arc...concerning same as electrode diameter used or tighter.

5. For welds on thicker metal, use several passes.

6. The lay wire method is popular, but dipping the rod is better for ensuring diffusion in the root pass.

7. If you dip, maintain the hot tip of the rod shielded with the argon as of the tig cup.

8. A gas lens works extremely well but is not forever essential.

Generation of the Plasma Arc (2 Ways):

2011-04-28T22:55:00.000-07:00

Plasma cutters produce the plasma in one of two ways: High-Frequency (HF) Contact or Pilot Arcs. Which one your plasma cutter uses depends on how old it is; the new high tech equipments use pilot arcs. The major dissimilarity is that HF Contact models have to close a circuit with a work piece that conducts electrical energy in order to cut while the pilot arc models can cut anything. They work in very different ways.

HF contact method of generating plasma is still found in low financial plan plasma cutters and in older plasma cutters. How it works is the plasma cutting component is connected to the work piece by a clamp and wire and when you touch the nozzle of the torch to the work piece an electric circuit is created. An electric arc zips from the work piece threw the plasma torch nozzle to the negative electrode inside the torch head. At the same time, pressurized inert gas runs in the opposite way, from the torch head out onto the work piece. As the gas surges past the zapping electric arc it is heated to around 50,000 degrees Celsius. At that heat the gas becomes plasma which is a form of matter that is a liquid and a gas at the same time. It is this super hot, super fast moving plasma that cuts the metal. The HF contact technique is said to contain one cycle since the major plasma flow is created in one step.

The Pilot Arc technique is a two cycle procedure. First, a high power, low amperage circuit is used to make a small, high intensity flash in the body of the torch which creates a small pocket of plasma in the torch head (note that the plasma is previously produced in the torch without the required to touch the work piece, this is what eliminates the require for a conducting work piece). Now, you can use a trigger to ignite the main plasma arc that will be used for cutting whatever it is you desire to cut. Pilot Arc is the technique used in CNC plasma cutting applications.

Safety for MIG Welder:

2011-04-25T22:49:00.000-07:00

Welding is a proven technique of permanently melding two metals together. Metal Inert Gas (MIG) welding is a world renown and appreciated trade, however, the risks can out method the rewards of its manufacture if the proper MIG Welder Safety guidelines are not taken. MIG Welder protection should be the main concern of the practitioner, novice or master, it should not matter what their ability level is, and the correct safety measures should always be taken.

Some ordinary guidelines of security may seem common sense enough but sometimes employers may push out these guidelines, don’t let them. Even if you are welding on your own, it is very significant to follow all of the MIG Welder Safety protection in order to enjoy a safe, creative experience. Some examples of safety precautions are:

Make sure that all of your skin is covered and protected from the powerful UV light that is created. Just close your eyes for a quick tack will not insure that you will not get arc eye. (Arc eye is an extremely painful result of improper exposure to the welding light. The feeling of pins and needles being positioned in the eye is an ordinary description.)

Always make sure that the area you are working in has an enough exhaust system in place. If you have problem with extraction, be sure to wear a breathing mask. Never have everything that is flammable wherever close to where you are working.

Never fail to remember the basic MIG welder security guidelines and never attempt to weld with no an instructor if you are not considered a professional.

The Best Diesel Generators - Everlast:

2011-04-21T05:41:00.000-07:00

If you are interest in receiving something that is quite portable, then think a unit like Everlast Diesel Generators. In everlast having many models some of the models are DP15000EDS and DP18000ED. Both models weight is 1001 Lbs so it is not something you want to carry long distances but it is still portable and it will provide (DP15000EDS) Max AC Output: 15000W, Rated AC Output: 13500W and (DP18000ED) Max. AC Output: 18000W. Rated AC Output: 16500W of powers so you can get a lot of use out of it if you take this unit camping or to a remote place where you require using power tools. Both model dimension is 65"x29"x40" and Long 8-Hour Run Time at Full Rated Output. Long 12-Hour Run Time At 50% Rated Output.

If you desire to save some cash and still get a unit that is very functional, take a look at the DP6500ATS Diesel Generator. This is a Maximum Surge Output of 6500W diesel generator that is going to distribute ample power for most applications. It has some standard features like oil alerts, fuel gauge voltmeter, oil warning light, circuit breaker for protection etc. For smooth and quiet operation it is enclosed in steel frame which is very rigid and isolated by motor mounts. It has an air cooled diesel engine with 11.0HP. It includes full power panel with engine shut off switch, hour meter, voltage selector etc... The idle control feature of this generator saves fuel and reduces noise.

Some Points about Used Plasma Cutters:

2011-04-18T05:34:00.000-07:00

1. Knowing the metal thickness that you will cut through earlier is actually helpful when shopping for a used plasma cutter. Knowing your preferred cutting speed is helpful as well. If you require cutting through 3/8" steel at 10 in/minute for example, you’ll find used Everlast plasma cutters very acceptable. If you need to cut through 3/8" steel at 75 in/minute, you will find a used Everlast PowerPlasma 50 plasma cutter satisfactory. Keep in mind that the thicker the metal, the slower the cut and this is true even with high capability cutters. Should you get into a conversation concerning ratings, remember that the normal rate is 10 in/minute.

2. Plasma cutter duty cycles point out a minutes per 10 minutes ratio of a rated capability. If you were to use a machine with a 70% duty cycle for instance, it could run at 400 amps for 6 minutes without having to be cooled. This information is critical when used plasma cutters function in hot surrounds.

3. When looking at your choices of used plasma cutters, make sure you can supply a stable stream of clean and dry air from an excellence air compressor. You will also require ensuring that any air compressor you use is able of satisfying an exacting cutter’s pressure necessities. Every cutter has a different requirement, so do not think that one air pressure is suitable for every cutter. You might find a small cutter with a built in air compressor, but if you are in the market for a big cutter, be ready to seek out an external compressor with a 40 - 60 PSI.

4. Portability is one more significant issue to address. In many cases, a cutter that sits idle for a while is not that big of a deal. A cutter that will be idle for a long time, such as during transportation for example, is a large deal as it can affect the machine’s unit delay.

5. Do not forget to verify that all controls are simply accessible and functioning. All analytic lights should work and consumables (including and air filter and dryer) must accompany the whole machine at either a very little fee or at no charge at all.

6. You will also desire to see if the product’s warranty is still in effect. This will help you get your used plasma cutter serviced. If you can locate the cutter’s producer, and that manufacturer is local and still in business that is even better.

7. Upon closer assessment, avoid buying a used plasma cutter that has broken cables, dirty inside compartments or other visual signs of spoil. These types of signs point out a very short life span and/or expensive repairs down the road.

Plasma Cutter Safety:

2011-04-15T05:28:00.000-07:00

There are a little things regarding plasma cutter safety that are different from common welding safety tips. This small list of plasma cutter safety tips is geared toward light duty plasma cutting using compressed air not large manufacturing units that use gas mixtures and water cutting tables.

Electric Shock Can Kill:

- Operating a plasma cutter completes an electric circuit between the torch and the workpiece. The workpiece and something touching the workpiece are part of the electrical circuit.

- Never touch the torch body, workpiece or the water in a water table when the plasma system is working.

Voltages & Currents:

- Plasma cutter output voltages are large amount greater than welding voltages, usually 100-200 volts.

Precautionary Measures:

- Don’t pick up the workpiece, including the waste cutoff, as you cut. Leave the workpiece in place on the workbench with the work wire attached during the cutting process.

- During plasma cutting processes don’t move the work clamp.

- Wear insulated gloves and boots, and keep your body and clothing dry.

- Don’t stand, sit or lie on or if not touch any wet surface when using the plasma cutter system.

- Insulate yourself from work and ground using dry insulating mats or covers large sufficient to prevent any physical contact with the work or ground. If you must work in or near a damp area, use great caution.

The Advantages of Portable Diesel Generators:

2011-04-11T05:25:00.000-07:00

* One of the main advantages of diesel generators is fuel efficiency. Generators with diesel consume less fuel than those that run on gas. Some diesel generators consume only partially their fuel load when functioning in the same capability as other generator types. This is why diesel generators are great for supplying nonstop power. They can therefore be relied upon to continually power refrigerators, computers and even house medical equipment.

* A portable diesel generator is sturdier than its complements. It can run for a total of more than 2000-3000 hours before you have to gravely think major maintenance work. You can simply see proof of diesel engine sturdiness just by looking at other equipment that runs on diesel. Heavy duty vehicles for example last longer than lesser ones used for transportation because they run on diesel.

* Normal maintenance is not a problem. This is because there are no spark plugs to maintain. You only have to keep in mind to regularly alter the oil and clean your unit from as often as the product manual tells you to.

* A diesel generator is ideal for rough terrain and rough work. These generators are many times more dependable in rugged environments than gas units. This makes diesel generators just right for offsite construction work and outside behavior.

* You will hardly have a problem with your fuel basis with a portable diesel generator. Diesel is http://www.blogger.com/img/blank.gifavailable in huge quantities almost anywhere. Just as long as a gas station is around, you are sure to locate some diesel supply.

* Diesel can be safely used in the majority instances. It is fewer flammable than other fuel sources. Diesel generators also do not contain spark plugs, which further lessens the chances of freak fires. You get immediate protection for both your property and your generator unit.

MIG Welding Safety Tips:

2011-04-07T06:07:00.000-07:00

Welding is a proven method of permanently melding two metals together. Metal Inert Gas welding is a world renown and respected trade, however, the risks can out way the rewards of its production if the proper MIG Welder Safety guidelines are not taken. MIG Welder Safety should be the primary concern of the practitioner, novice or master, it should not matter what their skill level is, and the proper precautions should always be taken.

TIG welding torches:

2011-04-04T03:41:00.001-07:00

There are lots of different models of TIG welding torches and if you get the incorrect one, it’s similar to buying shoes that don't fit...painful. So which TIG welding torch do you want? First of all, you need to come to a decision whether to go with air cooled or water cooled.

If you are a hobbyist welder, air cooled is the method to go. Why? For one thing, water coolers cost minimum $450 and air cooled TIG welding torches don’t need a water cooler. That's why.

Once you choose between an air cooled vs. water cooled torch, then you still contain some choices to make. Like whether to get a large TIG torch or a little one, a TIG welding torch with a gas valve built in or not including, a flex head vs. a rigid head, a 12 foot vs. or a 25 foot torch, etc.

Here is a list of proposals to guide you to buying the right TIG torch for your position:

• If you want portability, a 26 foot torch is the way to go.
• For portable circumstances that need fairly high amperage similar to aluminum TIG welding, the large style air cooled torches similar to a number 18 or 26 are in order.
• For little precise and low amperage circumstances, a little gas cooled torch like a WP serious works great.
• If you can afford it, a coolant re-circulator like an Everlast Cool mate opens up your choices and lets you use attractive much any TIG welding torch you want.

The Work Process of MIG Welder:

2011-03-28T00:41:00.000-07:00

A mig welder runs off electricity and uses the electrical current to raise the temperature of the base metal and fuse the filler metal (MIG wire) together in an electrical arc. This is your welding process.

The electrical current is passed from the power point on the wall, into the welding power supply, through the welding torch. When the trigger is squeezed the current then travels through the contact tip onto the wire making the welding wire live and conductive.

On the part you want weld, you attach the "welding earth" lead. Then when the MIG wire touches the earthed part, the electrical circuit is complete. As a result, the electricity starts to flow making a flash of sparks and an arc is created.

This arc is welding, without it you have nothing. Remember that "arc welding" is the process of welding using electricity. Mig welding is still arc welding as it uses electricity to make an arc, it's just that we call it MIG welding.

Welding Methods:

2011-03-24T00:31:00.000-07:00

There are three types of welding methods to consider. They differ by speed and cost. The methods are all available to all welding and hardfacing products. However, specific products often have properties that are somewhat unique and not exactly duplicated when utilized by a different process.

Stick Welding:

Manual or stick welding requires the least amount of equipment and provides maximum flexibility for welding in remote locations and in all positions. Typically, each rod permits welding for about one minute. In seconds, one can change from mild steel to stainless to hardfacing. In seconds, the electrode can change from small to large diameter for small or large welds. Although simplest, this type of welding takes the greatest operator skill.

Semiautomatic:

This type of welding uses wire feeders and continuously fed electrodes. The welding gun is hand-held by the operator. The gun keeps feeding wire as long as the trigger is depressed. This is also much easier to learn than stick welding. This type of setup is becoming more popular on farms, which do more than minimal repair work. Semiautomatic welding increases deposition rates over manual welding because there is no need to stop after burning each rod.

Automatic:

Requiring the greatest amount of initial setup, automatic welding has the highest deposition rates for maximum productivity. The welding gun is carried by a mechanized carriage and the welding operator just pushes a start button. This would rarely be found on a farm, but is common at repair centers for heavy equipment that would rebuild your parts for you if the schedule was mutually acceptable.

Welding Project Ideas:

2011-03-21T00:25:00.000-07:00

Thanks to the ongoing processes of technology - which, after something has been invented, tend to steadily simplify it, make it cheaper, and make it more suitable for general use through miniaturization and suchlike developments - welders are now available to the general public at a relatively inexpensive cost. Compact, high-quality, low-cost portable welders are now marketed which offer any handyman or tinkerer the opportunity to make use of this extremely convenient joining method.

The uses of welding are many and varied, ranging from the aesthetic to the practical, from small, intricate objects to large ones such as the frames for light outbuildings. A welder can be used in automotive work, for example. Resistance spot welding is often used to fit sheet metal patches into body panels where areas of rust or severe damage have been cut away, using resistance spot welding technology because ordinary spot welders cannot touch both sides of many car panels due to their being welded to the frame. MIG welding is often used for fixing patches in place as well, with initial spot welds to tack the new metal in place and a continuous weld to finish the job off.

Plasma Welding Guidelines:

2011-03-17T00:19:00.000-07:00

Plasma-welding-tips are useful reminders intended to stress the main characteristics of Plasma Arc Welding (PAW) for the correct exploitation of its specific advantages.

The first of the Plasma-welding-tips is a correct definition of PAW, useful for understanding the differences that make the process unique.

Plasma Arc Welding is defined as a gas shielded arc welding process where the heat for welding is generated by an arc producing collimated plasma by the passage of the shielding gas through a constricting nozzle.

The copper alloy nozzle is called constricting because it presents a limited diameter orifice, through which the shielding gas, highly ionized by its transit through the arc, must pass.

The concentrated and collimated jet stream of ionized gas (composed of nearly equal number of electrons and ions of gas atoms and molecules) that exits at very high temperature (about 17,000 0C or 30,000 0F) from the constricting nozzle is called a plasma column.

Plasma Arc Welding can be performed with or without additional filler metal. In manual applications, the filler metal as added as needed by hand. In the mechanized version, the filler metal is added from the side by a wire feeder.

Plasma-welding-tips concerns understanding the specific features of the process detailed below, and using its capabilities for obtaining successful welding results.

Robotic Stick Welding:

2011-03-14T00:12:00.000-07:00

Shielded Metal Arc Welding (SMAW) is frequently referred to as stick or covered electrode welding. Stick welding is among the most widely used welding processes. The flux covering the electrode melts during welding. This forms the gas and slag to shield the arc and molten weld pool. The slag must be chipped off the weld bead after welding. The flux also provides a method of adding scavengers, deoxidizers, and alloying elements to the weld metal.

Stick Welding Benefits:

• Equipment used is simple, inexpensive, and portable.
• Electrode provides and regulates its own flux.
• Lower sensitivity to wind and drafts than gas shielded welding processes.
• All position capability.

Stick Welding Discontinuities:

• Undercut
• Incomplete fusion
• Porosity
• Slag Inclusions
• Cracks

Stick Welding Problems:

• Arc Blow
• Arc Stability
• Excessive spatter
• Incorrect weld profile
• Rough surface
• Porosity

Mig Welding Gun Liner:

2011-03-11T00:00:00.000-08:00

Inside the whole length of the mig welding gun is a mig liner. The liner is a length of steel wound conduit that is fitted into place and has the welding wire running inside of it. The steel liner looks like the same stuff that they use in flexible drive shafts for whipper snippers, and it also looks the same as the flexible white plastic coated springy cord that you can hang curtains from.

Liners are available in different sizes and lengths. The deal is that you buy a liner that is as long as, or longer than your welding cable. If it is longer than you need, you just use some pliers and chop some off the end. The liner will travel starting from the welding machine euro connection (or whatever connection there is) to the back of the contact tip holder. The firmness of the steel liner will allow safe passage of the mig wire and help prevent feeding issues.

You can also get plastic or teflon liners. These are used for when you have to feed aluminum wires. This is because the wire is very soft and the metal liners have more friction in them than the plastic ones. Some brands and models of welding guns will have a two piece kit.

Kinds of Underwater Welding:

2011-03-08T23:53:00.000-08:00

There are three kinds of underwater welding. These are wet underwater welding, coffer dam welding, and hyperbaric welding. Each kind is completely unique from the others and has specific processes that have to be followed.

Wet underwater welding is done using the manual metal arc welding (MMA) process most commonly. Flux-cored arc welding (FCAW) used to be used in the former Soviet Union. Friction welding has a lot of potential to be used in deep water repair, especially if something needs to be repaired where people can't go. It mainly is done using robots.

Coffer dam welding consists of a steel structure that is sealed against the side of the structure that needs to be welded. It is open to the atmosphere and houses the welders in dry air, making it easier to do the welds.

Hyperbaric welding is done by sealing a chamber around the structure to be welded, and then filling it with gas. Helium is commonly used. The gas fills the chamber to a higher pressure than the water around and pushes the water out. More recently, transparent enclosures around the area to be welded are being used. The welder/diver then welds using several MMA electrodes in turn. They work from outside the chamber and the electrodes are already positioned through a flexible port in advance. The enclosures are made for every joint needing to be welded, and this process costs much less than the conventional method of making a large chamber.

Mig Welding instructions:

Mig welding tips presented hereafter review important aspects and point to special features of this popular process, officially designated as GMAW - Gas Metal Arc Welding.

The still popular name MIG (Metal Inert Gas) was initially adopted when the inert gases used to weld aluminum were only argon or helium. Later on, the introduction of mixes of active gases like oxygen, hydrogen and carbon dioxide to weld other metals too, suggested the need to drop the word "inert" from the description, with the adoption of the accepted new name.

Although Mig-welding-tips should be universally known, being the process quite diffused, widely popular and successful in numerous applications, it is contended by no less authority than Ed Craig, a universally acclaimed world expert, that unfortunately many misconceptions still limit its use.

ARC Welding:

2011-03-01T23:19:00.000-08:00

A Popular Method:

Representing 20% of all robotic applications, arc welding is one of the most common functions in industry today. During this process, electricity jumps from an electrode guided through the seam, to the metal product. This electric arc generates intense heat, enough to melt the metal at the joint. Sometimes the electron is simply a conductor that guides the arc. Other times the rod or wire is composed to become part of the weld.

Creating a Fusion Bond:

The resulting fusion bond is a seamless addition to the product. The mix of metals has the same strength as the original metals. This is one of the reasons arc welding is preferred to soldering or brazing. Non-fusion methods can be weaker because they fail to duplicate the mechanical and physical properties of the metals.

Automated Arc Welding Benefits Include:

• Consistency of quality welds
• Repeatability
• Lowered production costs
• Fewer scrapped parts
• Increase your return on investment (ROI)
• 100% warranty
• Hands-on robot training
• Fewer injuries from weld splatter or fumes
• Speed - faster part cycle time

Arc, Spot Welding Techniques:

2011-02-24T23:15:00.000-08:00

Welding has become an integral part of the lives of many people. Just like there are various different welding machines available, all the way from Diesel Welders to Pro-Arc's, there are also numerous welding techniques that can be used. In this article, we will cover some of the popular welding techniques like:

(1). Arc (2). Spot

Here, we will talk about why Arc welding is important. Arc welding is usually done by making use of a diesel welder. In arc welding, high electric voltage is used, instead of a gas torch. The arc, or the spark, created from the electrode rod, used by the welder, is transferred from one metal to the other metal. This in turn causes the metals to heat up and melt together which creates a bond or a weld amongst them. Arc welding is known to create cleaner, smoother, accurate and stronger welds.

The second technique to be discussed is the Spot technique. In this method, the two metal sheets are held together tightly by the electrodes. The surface area of contact between the electrodes and the materials is very small, and hence it is called 'spot' welding. When a large amount of current is passed through the electrodes, it heats up the spots to the point of melting, which results in a sturdy weld. This technique ensures that the rest of the metal isn't heated up unnecessarily and also takes lesser time.

Instructions of Spot Welding:

2011-02-21T23:09:00.000-08:00

1). Slide the sheet metal gauge onto one edge of the sheet metal to determine the thickness of the metal. When the sheet metal fits snug in a sheet metal gauge slot, read the number above the slot. This will show the thickness of the metal.

2). Set the hold, weld, squeeze and off-time of the spot welder by locating the thickness of the sheet metal on the welding chart affixed to the spot welder.

3). Clean the tips of both the top and bottom electrode by sliding the file over each tip. To weld correctly, the tip of each electrode should have no black carbon deposits.

4). Put on your leather work gloves.

5). Turn on the spot welder and open the cold water supply valve to flow water through the electrodes.

6). Stack the two pieces of sheet metal on top of one another.

7). Set the stacked pieces of sheet metal on the bottom electrode of the spot welder.

8). Depress the pedal of the spot welder to lower the top jaw of the spot welder and weld the sheet metal.

9). Twist the welded sheet metal a quarter-turn before releasing the pedal to avoid pulling a welding electrode from its socket.

10). Attempt to pull the sheet metal apart. If the metal bends rather than pulls apart, the spot welder is set correctly. If the spot weld breaks, increase the weld time of the spot welder and repeat the listed steps until you achieve a proper spot weld.

Auto Darkening Welding Helmets:

2011-02-17T22:29:00.000-08:00

While some people still stick to using standard welding helmets, auto darkening welding helmets are now gaining more popularity in the market. Helmets with auto dark lens could decrease the penetration of light whenever it is energized so that the lens appears dark in the center but light towards the outer areas. It also gives lighter, clearer views in angles that are not perpendicular to the surface of the filter. It’s really easier and more comfortable to work with helmets that have auto dark lens. They normally come with filters too that protect the eyes from ultraviolet or infrared rays.

Since this type of welding helmets darken and lighten up automatically, those who use it do not need to take it off as they work. There is no need to adjust the shade since it’s quite automatic. It generally costs more than the standard helmets though. The price of auto darkening welding helmets normally range from a hundred dollars to five hundred dollars, with more expensive ones offering more features or being made of more pricey, durable and flexible materials.

Inert Gas Welding and Spot Welding Difference:

2011-02-14T22:20:00.000-08:00

Unlike inert gas welding, spot welders do not require a shielding gas to eliminate weld contamination or filler metal to build up the weld.

A spot weld is a resistant weld that sits within the two pieces of metal. The finished weld is flush or slightly recessed to the exterior of the base metals and has a silvery or coppery appearance. The color of the spot weld will vary by the alloy of the metal being welded and the type of electrodes used to create the spot weld.

An inert gas weld is built up in a gap between two pieces of metal. The finished weld is humped up above the base metal and is easily visible. The high amount of heat generated by inert gas welding can cause the base metal to warp and twist.

Welding Procedures:

2011-02-10T22:12:00.000-08:00

There are five basic steps when welding that must be followed.

• Proper Preparation - You first need to ensure that the metal you are welding is clean and dry. Remove rust, dirt, grease, oil and other contaminants by wire brushing. If not removed, these contaminants can cause porosity, cracking and poor weld deposit quality. You must also remove badly cracked, deformed or work-hardened surfaces by grinding, machining or carbon-arc gouging.

• Proper Preheat - The combination of alloy content, carbon content, massive size and part rigidity creates a necessity to preheat in many welding or hard facing operations. Most applications require preheating, as a minimum to bring the part to a room temperature of 70ƒ-100ƒ F. Medium to high carbon and low alloy steels may require higher preheat to prevent under bead cracking, welding cracking or stress failure of the part. Preheating can be done with a torch, oven or electrical heating device. Special temperature-melting crayons can help you verify proper preheat. Too much heat and you can often ruin alloy materials!

• Adequate Penetration - Correct Welding Procedure - Identify the correct amperage, travel speed, size of weld, polarity, etc. Make sure the completed weld meets your expectations in regards to size and appearance. Welds should be smooth and uniform, free from undercut or porosity. If possible, watch a video showing the type of welding you will be doing so you know what things are suppose to look like.

• Proper Cool Down - Preheating is the most effective way of slowing the cooling rate of massive or restrained parts, which are inherently, crack sensitive. Insulating the part immediately after welding with dry sand, lime, or a glass fiber blanket also helps minimize residual cooling stresses, weld cracking and distortion. Never quench a weld with ice or water as this will lead to greater internal stresses and potentially weld cracking.

• Post Weld Heat Treatment - Some items may require tempering or heat-treating. What this means is that you warm the item up with your torch after welding and allow it to slowly cool.

Flux-Core Arc Welders:

2011-02-07T22:05:00.000-08:00

Flux-Core Arc Welders use a wire that, in its core, contains materials that release the shielding gases necessary to be able to protect the molten metal from the environment. There is no need concerning any external shielding agent, and also the shielding gases released by the wire can even withstand powerful breezes.

The drawback to the Flux-Core Arc Welders is that they use a fairly forceful arc, creating a large amount of spatter. Additionally, there can end up being slag on the final welding job, as well as it's going to end up being removed for a neat, clean finish. Extra disadvantages can appear as a result of mechanical troubles, like irregularity in the wire feeding. The filler material will be also a lot more costly than that compared to a Gas-Metal Welders.

How to weld sheet metal using a stick welder:

2011-02-04T21:57:00.000-08:00

The real trick to welding thin metal is to use a wire feed. Just kidding, this tip is to explain how to do it with a stick welder. A wire feed or tig welder is ideal for sheet metal, but we will assume that you don't have one. We need to establish what is considered thin metal. There is no absolute "according to Hoyle" answer, but I always considered anything less than 3/16″ to be thin. So from this point on we are talking about less than 3/16" material.

The first thing to figure out is what kind of welding rods and what size of welding rods to use. If you have nice new 1/8″ material, I would go with 3/32″ 7018 rods. If you have old rusty painted up 14 gauges, I might be inclined to use 1/8″ or 3/32″ 6011 rods. You might ask me, why don’t you just grind the rust off? Well if it’s just surface rust go ahead, but if it’s pitted out you will grind all the material away before you get it clean. Not only have that, but if you are just doing a quick repair job on something, just welded it. Chances are, if the material is that bad the weld will far out last the rest of the material anyway. Back to my point, 6011 is the rod I will pick anytime. It allows you to move a lot faster than 7018’s will.

As far as the actual welding goes, I like to use a whipping motion with the welding rod following the same direction as I am welding. Basically just a back and forth motion. The reason for this is to keep from building up too much heat all in one spot. If you were to drag the rod slowly you will have a pretty good chance of burning through. If you are welding vertically, don’t be afraid to run the 6011’s downhill. If the material is really thin, I will use the whipping motion downhill as well. I know it goes against some principles of burying slag but, when the material is thin it really doesn’t matter as much.

Most anything that is made from thin material is over welded. Say for instance you are patching an air compressor tank that has a hole rusted in it. You will weld the patch 100% because it needs to be air tight, not for strength. If you are making a section of air duct, you will weld it solid for air and not for strength, you get the point.

I guess the moral of the story is you can do just about anything with a stick welder in a pinch. It only takes a little bit of practice to make it happen. Just grab a piece of sheet metal to get the heat set correctly and go to town. A good heat setting for 1/8″ 6011 rods on thin material is about 80-90 amps. For 3/32″ 7018’s it’s about the same. Everyone is different but, those settings will get you in the ballpark.

MIG Welding Overview:

2011-02-01T21:50:00.000-08:00

There are four primary methods of metal transfer in MIG welding: globular, short-circuiting, spray, and pulsed-spray. Each of these has distinct properties and corresponding advantages and limitations. Schrimpf Welding offers a variety of MIG Welding services depending on the individual details of the project. For the most comprehensive advice, we recommend contacting us with the specifics of your project, and we will be happy to supply you with a free estimate.

Some of the advantages to MIG welding are:

• Continuous weld, due to the continuous spool
• Almost no cleanup
• You are able to weld in all positions
• Can weld stainless steel, mild steel, and aluminum

Advantages of SAW (Submerged Arc Welding):

2011-01-27T23:32:00.000-08:00

-It has a high deposition rate and it can penetrate the weld deeply.

-When you have designed a good process and you have control over what you are doing you can be sure that you get a strong weld.

-You can actually do this with thin sheets of steel and they can be done at a higher speed.

-There are very minimal fumes or arc lights which makes this a safer process.

-You can do this indoors or outdoors.

-You don't have a lot of distortion.

-You don't get any spatter on the weld because the arc is always under the blanket of flux.

-As with any technique there are a few limitations with the SAW method that include:

-You are limited to only a few positions that you can use this within.

-You can only use steel, stainless steel or a few nickel based metals.

-The flux handling systems can be more complex and difficult to use.

-Slag is a problem in a couple of ways: you can get residue from it that may cause some issues with your health or with safety and it will require a complicated slag removal system.

Five Ws of Welding: (Part - 2)

2011-01-24T23:27:00.000-08:00

When was the welding process formed?

This process was formed before several millennia and the earliest examples are Bronze Age and Iron Age and middle age is the period that brought some advances in welding. In the year 1540, the vannoccio published the descriptions that include forge operation. In 1802, the Russian scientist proposed the practical applications of electric arc that also includes welding. In world war, the welding processes were widely used and 1920 was the year in which some major advances in welding technology and machines were used.

Who uses the welding processes the most?

As stated in the starting of the article, the manufacturing industries use this process the most and industries like, ship building, aircraft, motor manufacturing, automotive industries, electronic industries and in construction industries the welding process is widely used.

Where to get efficient welders?

Search in internet, you get a variety of manufactures who provide these welding machines in a quality and efficient way. Search for the best products in the market and also, before buying those machines, make sure that you get the machines that are quality and that have efficient duty cycle.

Five Ws of Welding: (Part - 1)

2011-01-20T23:21:00.000-08:00

What is called as welders and what are the different types of welders available?

Why plasma cutter is called as the scientific welding machine?

Who uses the welding processes the most?

When was the welding process formed?

Where to get the efficient welders?

What is called as welder and what are the different types of welding machines available?

Welder is a machine that does the welding process in a most efficient way and most of the people get confused with the term welder and weldor. As said above, welder is a welding machine and the weldor is the people who do this welding process. The different types of welding machines available are tig welder, arc welder, mig welding machine, plasma cutter and etc are the different types of welding machines available.

Why plasma cutter is called as the scientific welding machine?

Plasma cutting machine is called as the scientific welding machine because in this process it uses the gas called plasma and it is a state of matter that is used in science. It does the process in a accurate and faster way and performs the dual role and act as both plasma cutting and arc gouging machine.

Pre-Power verification of Inverter Based Welder:

2011-01-17T23:15:00.000-08:00

The following steps should be performed:

1. Test the functionality of the Power Switch. Confirm that it has continuity in the ON position, and provides a disconnect (is open circuit) in the OFF position. Check all poles of the Switch.

2. If the Inverter is capable of operating at multiple input Voltages, confirm the functionality of any external voltage selection Switches.

3. When the Inverter is first powered up the Bus capacitors (Main filter capacitors) are pre-charged for several seconds. This is to limit the inrush current, as a capacitor appears as a short circuit to the incoming power supply (Mains input Supply) at time equal to zero. If this is not done, the Input Rectifier and Main Power Switch would have to supply infinite current during this time (an impossible situation that eventually results in component failure). A high wattage resistor limits this initial current. Confirm that this resistor is not open circuit, or degraded.

4. Visually inspect the Bus Capacitors. These are normally large Radial electrolytic Capacitors. Confirm that the cases are not distorted, and that they are sealed (not leaking electrolyte). Ensure that the Bus Capacitors are fully discharged. Measure the value of the capacitors using a Capacitance meter.

5. With a DVM (Digital Volt Meter) placed in the Diode position, confirm that the Mains input Rectifier, and Secondary output diodes are functional. The diodes should show a forward voltage drop of between 0.2 to 0.8V DC when the Anode is positive in respect to the Cathode. An Open circuit condition (displayed as OL on some DVM's) will be shown when the probes are reversed.

Gas Tungsten-Arc Welding:

2011-01-12T22:31:00.000-08:00

Gas Tungsten-Arc Welding (GTAW), also known as Tungsten Inert Gas or TIG welding, uses tungsten electrodes as one pole of the arc to produce the heat necessary. The gas is generally argon, helium, or a mixture of the two. A filler wire provides the molten material if needed.

The GTAW (Gas Tungsten-Arc Welding) process is particularly suited to slim materials producing welds of outstanding quality and outside finish. Filler wire is generally chosen to be similar in composition to the resources being welded.

Atomic Hydrogen Welding (AHW) is similar and uses an arc between two tungsten or carbon electrodes in a shielding atmosphere of hydrogen. So, the work piece is not division of the electrical circuit.

What is Plasma?

2011-01-10T22:26:00.000-08:00

If you improve a gas to very high temperatures, you obtain plasma. The energy begins to break apart the gas molecules, and the atoms start to split. Usual atoms are made up of protons and neutrons in the nucleus, bounded by a cloud of electrons. In plasma, the electrons divide from the nucleus. Once the power of heat releases the electrons from the atom, the electrons start to move around quickly. The electrons are negatively charged, and they go away at the back their positively charged nuclei. These positively charged nuclei are recognized as ions.

When the fast-moving electrons crash with other electrons and ions, they release huge amounts of energy. This force is what gives plasma its sole status and incredible cutting power.

Used Plasma Cutters:

2011-01-06T03:58:00.001-08:00

You can find used plasma cutters internet and in the actual world. If you discover used plasma cutter you have to make in no doubt that it is in fine condition and, more importantly, you have to find out if the component meets your requirements. Use the following list of questions to assess any used plasma cutter that you find. When you have the answers, you will be in a much improved position to create a knowledgeable buying result.

1. Is the cable insulation worn down from use?
2. Does the sever cut, rated cut, and quality cut of the match what I need?
3. Are the cuts still clean?
4. Has the machine ever been repaired or serviced?
5. Is there still a factory warranty?
6. Is there a power source at my business or home that matches the power requirements of the machine?
7. What is the duty cycle of the unit?
8. Are the diagnostic lights and controls functioning properly?
9. If I buy the machine do I get any consumables?
10. What is the condition of the internal components (if they are in good condition then the owner probably taken good care of the machine)?

How MIG Welding is well-liked today?

2011-01-03T03:53:00.000-08:00

1. Very easy to weld using a mig.
2. Faster and quicker process.
3. It's more economical.
4. Can be used with robots and automation.
5. Can use a shielding gas to give very smooth welding bead appearances.
6. A variety of metals can be joined.

This is also identified technically as the gas metal arc welding procedure. This is as you can use what is called a shielding gas which will permit for far better control of the spatter. There are quite a few different types of gases that be able to be used today.

Some Bad effects of Diesel Generators:

2010-12-23T21:56:00.000-08:00

When a disaster strikes, your protection may depend on a dependable generator to kick in and save the day. There are many sizes and functions to a good diesel generator.

Here are some points to consider!

Noise:
In compare to alternating powered generators a diesel generator will typically be noisier. Depends on the size and place of your favorite generator you may require to check and explain local policies before installing and using a large unit.

Pollution:
Diesel isn't a 100% fresh production fuel. Exhaust removal will need to be charged proper to the type and location of the generator. Local systems will also apply here.

Weight:
They are heavier than their complement gaseous operated generators.

Installation process of Diesel Generators(part-2):

2010-12-20T23:35:00.000-08:00

Ventilation:

The Generator fixing features a sufficient format of intake, cool and clean air and proper drain of hot air from vent. For airing the whole size of room particularly designed for the cooling system and local operating circumstances because the work of room varies the temperature of generating power. It is highly suggested that the enhanced size of room can increase and typical size of room reduce the competence and temperature of the generators. Freshening auxiliary items generally includes warmer cooling fan, exhaust pipes to guide ventilation and cooling alternator to cool down engines in operation.

Fuel Storage:

Diesel Fuel is referred as a "Dangerous Fuel" and its storage space and allocation considered to have number of rules and regulations. On everlasting basis it is commonly store in huge storing tank or container. Generally, there are two accessible tanks which differs with essential fuel requirements. Tank with manual filling is normally used for manual start producing set which is actually checked and configured during checking of fuel level gauge. Tank with Automatic Filling is regularly positioned within the room, in this category fuel automatically accessible for power generation except it is proscribed through electrically charged fuel force that inserts fuel from automated fuel tank which shows through fuel injectors for burning process.

Starting System:

Starting an engine is simple when it succeeds, but may cause countless troubles when failed. The process of highly multifaceted equipment may depend on the consistency of the generator set mainly in applications such as hospitals, building protection systems and factory processes. The starting system plan depends on the engine heat.

Installation process of Diesel Generators(part-1):

2010-12-16T23:28:00.000-08:00

For an excellent generator performance and effectiveness, the installation using safety actions and quality plays important role in outfitted life of generator. After buying the generator of any fuel type you may also receive accurately structured installation guide that set according to assured requirements. The installation should be done under serious supervision of skilled technician to get completely satisfy from its installation. There are few necessary instructions that can be used for common type generators installation.

Location:

Before installation, set you should thinks some features like largely space, location state open type or closed type, drying system, ease of access feature, proper production control during fatigue process, maintenance feasibility. In fact there is no previous bounding to choose which location by area but the selected area should contain safety and security measures in process to difficult generator set working.

Easy to Access:

In the process of regular general protection the accessibility element should not be overlooked. For easy and safe accessibility essential access points should be prepared along crisis gateways. Easier access decreases liberator time and doubtful problems of generator set.

Sound Proofing:

The electrical power producing resolution generates massive amount of sound energy may also need to reduce the sound by original design of the installing system. To decrease reckon sound an added feature of sound proofing can shrink sound power to almost nothing though this process acquires lots of investment and costly than other two common techniques. The insulation is also sound checking process that can diminish the traveling sound through neighboring walls by group and sufficient
thickness.

Revolution of Welding tools in the industry(part-3):

2010-12-13T23:17:00.000-08:00

Accessories are the welders protection:

Welders are the people who are running in heat and have the ability of revealing to flame. So the welders should be sheltered well by garnishes such as gloves and helmets. Helmets protect the welders from the blast of heat to eyes. Helmets survive in different sizes and varieties.

Consumables the division of welding tools:

Consumables are the small tools which are used all along with welding tools. For different kinds of welding various consumables are used such as plasma consumables, mig consumables, tig consumables and tungsten.

Generators the option for electricity:

To run a business profitably continuous power supply is required. Generators are the substitute for electricity, they provides electrical energy when there is no power supply. Generators arrive in economy, deluxe and super generators based on the cast and purpose. Silent diesel generators have more features with 1000 hours of guarantee and it can be used for both residential and commercial purpose.

Revolution of Welding tools in the industry(part-2):

2010-12-09T23:11:00.000-08:00

Venture techniques in welding tools:

While buying the welding tools various aspects should be measured such as its function (ie) where you are use and for what substance it's going to be used. While buying, check the welding tool should be proper in size.

Modern products are the money-making products:

The aim of every industry is to give a quality product and to gain profit. To earn highest profit the equipments should be a modern one and should formulate the work easier. Spot welders tig welder's wire feeders and multi system is the tool with some superior design makes the work easier.

Plasma cutters the new discovery:

Plasma cutters have its basis in the world war itself. It is used to engrave the steel and metals with high width. When you decided to purchase the plasma cutter a variety of factors should be considered such as its function cycle and for what reason you are going to use either use it in the industry are going to take it along with you. Many power plasma sequences survives such as power plasma 50, power plasma 70 and power plasma 60 which is used for different functions.

Revolution of Welding tools in the industry(part-1):

2010-12-06T22:49:00.000-08:00

Welding is the method of joining the metals. Modern industries generally depend upon welding process. In olden day's welding process is the hard task and the same welding process is used for different types of metals. Due to the scientific improvement several welding tools and techniques came into the marketplace which offers you the greatest performance. You can see the well-known American statue is too made by welding process.

Welding tools are the back bone of the current industry:

When you decided to initiate an industry you should focus on the products which is necessary for the products should be efficient and a quality one. The most significant tool of welding is welder and welding equipments. Welding equipments like arc tig plasma cutters and trimmings such as welder gloves helmets are the most essential tools for the Welding industry.

Useful tips for Wire Feed Welders:

2010-11-25T04:14:00.000-08:00

Wire feed welding, which not like stick welding uses a wire flux to reinforce its weld, consists of two main types, first one is metal inert gas and second one is flux-cored wire welding. MIG welding gives a best overall appearance, as it causes fewer spatters, and works best with thinner materials. MIG welding needs more tools than flux-cored welding, however, as it uses an inert gas to shield the weld. Flux-cored wire has the protect built into it, but can only be used with soft steel.

Wire Extension:
Maintain your wire sticking out of the tip of the contact tube as MIG welding. One-fourth to 3/8 of an inch of cable should expand out at all times as you work, suggest the Everlast Welders website.

Wire and Metal Thickness:
When welding a slim metal, use thinner cable; use thicker cables for thicker metals. You may also require different sized machinery, based upon the size of the metal you are welding. Welding machines will regularly come with these specifications.

Wire and Metal Matching:
According to Everlast Welders, the cables you use should match the type of metal that you are welding; for ex, use aluminum cable to weld aluminum and steel cable to weld steel.

MIG Welding Gases:
Use carbon dioxide as your shielding gas as MIG welding on steel. Everlast Welders suggests using 75 percent argon and 25 percent carbon dioxide for slim steel, and argon gas alone to weld aluminum. For stainless steel, experts suggest a triple-mix of helium, argon and carbon dioxide.

Flux-Cored Wire Welding:
When welding with flux-cored cable, maintain your cable as dirt free and dry as you can. In addition, when you complete a weld, clean off the slag, or debris, from the top of the weld. A chipping hammer and a cable brush work fine for such cleaning.

Welding & Cutting Safety Tips:

2010-11-22T04:08:00.000-08:00

Cutting and welding of metals involve the application of high temperature to the things being welded or cut. This powerful high temperature is obtained from the use of inflammable gases, (ex., acetylene, hydrogen, etc.) or electrical energy. The intense welding warmth and the sources employed to create it can be potentially dangerous.

Therefore, to guard persons from damage and to guard building and gear against flames, etc., a set of advices about safety and health actions for the welders and those worried with the safety of the tools, etc., have been published by ISI and several other similar but International organizations.

By keeping in mind the following suggestions or precautions, the risks linked with welding can be mostly reduced. So, it is recommended that the beginner in the field of welding have to go through and become well-known with these suggestions which also have been discussed below:

1). Security advices for installation and operation of Gas welding and cutting tools.
2). Security advices for installation and operation of Arc welding and cutting gear.
3). Explosion, fire and additional hazards and defense against them.
4). Protection of welders.
5). Ventilation and health safety.

MIG Welding Advantages and Disadvantages:

2010-11-19T00:48:00.000-08:00

Advantages of MIG Welding:

• The most excellent option when cosmetic appearance is an issue since it provides lesser spatter levels than flux-cored. The arc is soft and fewer likely to burn through slim material.

• The lesser spatter connected with MIG welding also means no slag to chip off and quicker cleaning time.

• MIG welding is the simple type of welding to study and is more forgiving if the operator is somewhat unpredictable in holding arc length or providing a stable travel speed. Procedure settings are more forgiving.

• If you are skilled and get exact correct guns, shielding gas, liners, drive rolls, and electrode, MIG can weld a wider range of material including thinner resources and different materials like stainless, nickel alloys or aluminum.

Disadvantages of MIG Welding:

• Since a bottle of outside shielding gas is necessary, MIG welding may not be the procedure of option if you are looking for something that offers portability and convenience. MIG also needs extra equipment such as a hose, regulator, solenoid (electric valve) in the wire feeder and flow meter.

• The welder's initial job is to arrange the surface by removing paint, rust and any surface contamination.

• MIG has a soft arc which will not correctly weld thicker materials (10 gauge would be the highest width that MIG could soundly weld with the 115 volt compact wire feeder welder we are referring to or ¼" with the 230 volt input compact wire feeder welder.) As the thickness of the material (steel) increases, the danger of cold lapping also increases since the heat input wanted for good fusion is just not possible with these small machines.

Tips to Use Welding Machines:

2010-11-15T00:37:00.000-08:00

1). Decide the most excellent welding machine for your requirements.

2). Use a motor-generator welding machine in areas with no electrical energy. These types run on electrical energy, gasoline or diesel fuel and can make straight or alternating current.

3). Use an alternating power transformer machine for small industrial, garage or shop welding. These models are reasonably priced, lightweight and compact.

4). Consider rectifier welding equipment for jobs requiring both alternating and straight current. An easy flip of a switch permits the operator to decide the correct current for the job.

5). Make use of an electrode negative equipment if you are welding carbon and/or stainless steel. These types, powered by either diesel fuel or gasoline, are famous in construction work.

6). Clamp the ground wire to your workbench or straight to the thing you are welding. This produces sufficient heat and prevents damage to the welding equipment and its wires.

7). Consult the manufacturer's instruction guide for how to use your exacting type of welding equipment.

8). Clean your welding machines with a steel brush, chemicals or a power tool after each use.

9). Wear correct safety gear when using welding equipment, including a helmet, gloves and protective eye gear. Forever work in a well-ventilated region.

Spot Welder Advantages Limitations & Applications:

2010-11-11T22:32:00.000-08:00

Advantages:

* The procedure involves smaller amount maintenance money.
* Ability of the worker does not influence the quality of spot welds obtained by this procedure.
* The process is usually free from burn and splash.

Limitations:

* To achieve small cost of building, the weld manufacture cost is not very high.
* The procedure proves uneconomical as compared to resistance spot welding where the latter are able to be simply employed.

Applications:

The use of physically operated arc spot welding gun is an ordinary thing in a variety of industries. Arc spot welding is particularly applicable for situations where resistance spots welding wants high pressure, high currents, does not have simple access and therefore fails to weld.

Arc spot welding torch be able to also be working to make holes in plates up to 3 mm broad or consequently. After the arc has impinged on the plate for a exact time, high force inert gas blows away the molten metal leaving a hole in the plate. Additional applications of, the process are in:

1. Automobile manufacturing.
2. Manufacture of sheet metal goods.
3. Assemble sheet metal to steel structures.
4. Manufacture of pulleys.
5. Joining killed carbon steel, low alloy steel, high alloy steel, titanium, etc.

Why TIG Welding Is So Popular:

2010-11-08T22:36:00.000-08:00

TIG welding is a very accurate process that gives extremely clean welds with no splash and small amount of smoke. This makes it extremely beautiful for highly cosmetic applications, such as automotive, sculpture, experimental aircraft, and home-hobbyist jobs.

TIG welder is normally used in applications that have thin-gauge parts of stainless steel, chrome-moly tubing or lighter metals such as aluminum, and copper alloys. These thinner resources need exact heat control to prevent warping or burn-through of the foundation metal.

TIG welder machines efficiently function at the lower amperages that are wanted to give that control.

Short note on Basic arc Welding Circuit:

2010-11-03T22:07:00.000-07:00

The fundamental arc-welding circuit is demonstrating in the image. An AC or DC power source, fixed with whatever controls may be wanted, is linked by a work wire to the work piece and by a "hot" cable to an electrode controller of a few type, which makes an electrical contact by the welding electrode.

An arc is formed across the gap when the energized circuit and the electrode tip touches the work part and is withdrawn, yet still with in close contact.

The arc creates a heat of about 6500ºF at the tip. This high temperature melts together the base metal and the welding electrode; creating a pool of molten metal sometimes called a "crater." The crater solidifies behind the electrode as it is moved along the joint. The outcome is a fusion bond.

Benefits of TIG welding electrodes:

2010-11-01T00:28:00.000-07:00

• Make easy arc starting
• Enlarge arc stability
• Get better current carrying capability of the electrode
• Decrease the risk of weld contamination
• Boost electrode life

Oxides used are mainly zirconium, thorium, lanthanum or cerium. Added extras are usually 1% - 4%. These oxides very much increase arc initiation, particularly when direct current (DC) welding is working. Thorium oxide (thoria) has been used for a lot of years, have been establishing effective in terms of extended life and thermal competence. Zirconium oxide (zirconia) has been usually used for alternating (AC) TIG welding, usually for welding aluminum.

Diesel Generator Disadvantages:

2010-10-28T02:24:00.000-07:00

1). The important disadvantage of diesel powered generator is as it produces loud way of sound that be able to be indefensible at the majority of times.

2). The diesel generators more often than not take a few times to ignite than other electrical generators it in addition gives certain hindrances for the period of starting issues in cold situations.

3). The diesel generators are generally used in industrial applications since it emits risky quantity of injurious gases for the period of exhaustion and which is considered as susceptible in terms of release control policy of such countries. It also creates higher smoke than any other fuel reacting agent.

4). Normally, the fitting process and its period takes more time and consume higher price than fitting of other generators. It can be calculated as startup (installing) price is more than one forth to the actual cost of generating unit.

5). In case of ignorance of routine checkups to diesel generators the later than sales service of diesel generators can price way higher since mostly diesel contain big & heavy parts which also expenses higher in amount.

TIG Welding Overview:

2010-10-25T10:37:00.000-07:00

TIG welding is a successful way to weld slim pieces of stainless steel and light metals such as aluminum, magnesium, and copper alloys. TIG welding is hard to master and needs knowledge and concentration to detail. This kind of welding is a smaller amount of a fire hazard than other kinds of welding and is helpful if you want to weld a structure indoors or want a extremely exact weld. Some of the places that TIG welding would be used indoors are in restaurant and study labs. Occasionally tools such as vent hoods and stainless steel tables are set and want to be welded where they are seated. Schrempf Welding offers both mobile and in shop TIG Welding based on the particulars of the individual plan.

Submerged Arc Welding overview:

2010-10-22T02:29:00.000-07:00

Submerged arc welding is a small different than most other forms of welding since the arc and the end of the electrode are not able to be seen to the operator. Both are kept below a pile of grainy flux. The majority ordinary use for this welding scheme is by machines, but there are semi automatic versions. The machine is used to start the arc and gives the electrode by feeding it to the weld region from approximately a spool. The flux is in a granule form and is dispersed in front of the weld pathway. The scheme is able to also be set up with two electrodes positioned vertically side by side, vertically one in frontage and one in backside, or in a v-shaped to speed the procedure up. Some of the flux is melted in the welding process which generates a slag that helps guard the weld from the surroundings and from cooling. A few joints up to 3" wide are able to be welded in one pass. This technique is regularly done in a flat position and is great for ships and bridges where extended welds are wanted.

The slag in this situation helps to generate a clean and strong weld. With the arc enclosed up, spatter and heat loss into the nearby surroundings is not a trouble. Alloy and metal powders are able to be added to the flux grains in order to assist fill the seam. Not a lot of smoke is created if any and no defense is wanted to shield from the light from an arc. The system is automatic simply and there is not a lot of talent wanted for the procedure. The slag generated limits submerged arc welding to simply to a flat position. The heat that is generated by the weld stays in the metal longer due to the flux covering which can boost distortion of the metals.

Tips and Tricks for Stick Welding:

2010-10-19T02:37:00.000-07:00

Following are the some tips and tricks to assist get better your stick welding skills:

Select the correct electrode:

A lot of welders are not sure of the type and size of the electrode that must be used in stick welding. The dimension of the electrode you select ought to match the circumstances you are welding within and the kinds and thickness of metals.

Polarity matters:

If you buy an A/C only welding gear, then you require getting stick welding rods that are specially shaped to weld on A/C. Stand in mind that not all stick welding rods are shaped the same.

Do not use odd sizes for your metal:

Many metals come in exact sizes that are ordinary. These metals are a set easier to find and you be able to weld them earlier and much efficiently. You do not require to experiment on your metal assortment when it comes to stick welding.

Be familiar with your arc length:

For a winning stick welding job, you require to use an arc length that is the similar distance from the metal as the thickness of your electrode. For example, if you have an electrode that is ½ inch thick, then contain your arc ½ inch thick as fine. Do not fail to remember that as you use the stick electrode, you will want to move it closer to the metal.

Use of best auto darkening welding helmet makes you a improved stick welder:

A best auto darkening welding helmet is very significant in stick welding. The majority experts advised a welding helmet that darkens in 1/20000 seconds, be able to be attuned from 9 to 12 shades, and has delay and compassion features. You want a best welding helmet for you to see obviously where you are striking your arc and to alone will make you a best stick welder. Sideways from that, it is able to also guard you from the injurious UV and IR emissions from the arc.

Tips for buying an Electric generator:

2010-10-15T02:28:00.000-07:00

Do not press it to the max:

Make in no doubt you are compare the rated capacity of a variety of models, not maximum capability. An electric generator can produce its maximum capacity for no more than 30 mins previous to starting to overheat - rated capacity is the level of power a generator can produce on an ongoing base. Normally, it's approximately 90% of the maximum power.

Include all you require:

Few of the more significant devices to connect to a standby generator are a number of of the smallest amount able to be seen: sump pumps, sewage ejector pumps, and ventilation fans. Do a cautious inventory of your electrical devices previous to committing to a sure wattage level.

In addition to not anything you don't:

The solitary most excellent way to save money on a standby generator is to limit the amount of devices you expect it to power. Think that the majority power outages last a smaller amount than a day – cannot your office deal without air conditioning for a small number of hours?

Twist to the pros for fitting:

Knowledgeable interior electricians may not be as well-known with electric generators as they are by other types of electrical systems. Decide somebody who's installed standby generators before and make sure they do all work up to code.

Be expecting infrequent exercise:

Standby generators start themselves up around once a week to "exercise" - make sure they are prepared when wanted. This simply takes approximately 15 minutes, but if sound is a worry, some generators have a "low idle exercise" feature that lets them run quieter than common during this weekly workout.

Tips for Spot Welders:

2010-10-12T00:17:00.000-07:00

Spot welding tips require be sizing and matching to the exact thing that is being welded. The many styles of tips permit for the welding of a lot of sizes and types of metal. The key to finding a best brand is finding a tip that has best conductivity and is completed from a very pure alloy. This will permit the tip to reach the maximum temperatures and not deform.

The most common spot welding tips types:

Truncated cone, radius faced angled straight tip, offset nose, sharp nose, dome nose and flat nose. Truncated cone tips seem like a 45-degree cone with the top compressed out. Radius face tips are rounded crossways the entire tip in a 45-degree arc. Angled straight tips are tips that come to a in a straight line point and contain a 30-degree viewpoint cut crosswise them. Offset tips have one in a straight line edge that come flat nose tip with 45-degree viewpoint. A point nose tip comes to a point with a flat welding face. A dome nose tips have a half circle tip with a very little welding face. Flat tips are totally flat with the complete tip being the welding face.

Tips for TIG Welding:

Welder’s caps or welders beanies (cap with no peaks) are available from all welding equipments providing stores.

Compare Plasma Cutter and Oxyacetylene:

2010-09-29T23:46:00.000-07:00

Plasma cutter can be perform on some category of conductive metal - mild steel, aluminum and stainless are a few examples. By mild steel, operators will practice faster, thicker cuts than with alloys.

Oxyacetylene cuts by burning throughout the metal and is so limited to steel and other ferrous metals. Plasma cutter produce sufficient power to melt the metal and then creates the momentum to blow it away. Since of this, plasma cutter can cut non ferrous materials, has a lesser ability level and offers sooner travel speeds. In addition, it does not need the use of flammable or explosive resources and is so, safer to work.

The only drawbacks are that plasma cutting machinery is much costly than oxyacetylene, and too, oxyacetylene does not need access to electrical power or compressed air which can create it a more suitable technique for a few users.

Stick, the majority basic of welding processes, offers the easiest selection for combining steel and any other metals. Stick welding power sources deliver inexpensive choice for welding versatility, portability and reliability. Stick welding connects metals when an arc is struck between the electrode and the work part, creating a weld pool and depositing a consumable metal electrode into the joint. The electrode's protecting coating also acts as a shielding gas, protecting the weld and ensuring its cleanliness and power. Most excellent for windy circumstances and unfavorable environments.

Shellfish is able to create you a best welder. Just think about CLAMS: Current setting, Length of arc, Angle of electrode, Manipulation of the electrode and Speed of travel. If you are just learn the Stick welding process, technically called Shielded Metal Arc Welding, remembering these five points will improve your welding technique.

An overview on types of welding

2010-08-23T04:16:00.000-07:00

Welding industry has developed a lot and many welding techniques are followed and new welding machines have been introduced. There are different types of welding process and each one has its own merits and demerits. Arc welding is a welding technique that uses a welding power supply and creates electric arc between electrode and base materials and Forge welding is a process that joins metal by heating them to high temperature. Tig welding uses tungsten electrode to produce the weld and it is the other name for gas tungsten metal arc welding and it is used to weld thin sections of stainless steel and non ferrous metals. Mig welding is an automatic arc welding process preferred for its versatility and speed and weld aluminum and non ferrous materials. Spot welding is a process in which metal surfaces are joined by the heat obtained from resistance of current flow. Gas welding is also called as oxy-fuel welding and use gases to weld and cut metals. Stick welding or shielded metal arc welding is a manual arc welding process that uses consumable electrodes. Plasma arc welding uses plasma gas and has narrow penetration with greater energy concentration.

Precautionary measures in welding

We know that welding is a process which deals with heat and flames so there is a possibility of getting some severe injuries and if no precautionary measures are followed, it may even let to death. Let us have a look on some precautionary measures to be followed in welding

• Wear protective gears such as goggles and welding helmets
• Keep combustible materials away from the workplace
• It's better to have a fire extinguisher in the welding industries
• Welders should definitely wear protective clothes made of durable materials
• Have steel toed boots and ear muffs
• Welding work should be done in proper ventilated space
• The old machines should be replaced by a new one and standard operating procedures should be followed
• The welding industries should be equipped with proper respiratory protective equipment and the precautionary measures should be displayed in all parts of the welding industry
• Do not breathe fumes use fume collectors and respirators
• Avoid standing on wet floors and perform the welding operation with the standard electric circuit with rated capacity

How to get a welding certification

2010-08-09T00:00:00.000-07:00

Welding is absolutely not an easy trade and is one of the hardest when it comes to proving yourself. For mastering the welding technique, you need to master codes, specifications and procedures and also prove all this time after time. You can be a certified welder once you attain the certification papers. The papers authorize that you have passed a welding test.

You can become a certified welder by passing the test but that does not necessarily make you an expert welder who is good hand. Sometimes you may find yourself spending hours welding test plates at the weld school. This would surely enable you to polish your talent and pass the code to become certified. But all the certification is not enough when it comes to working at the job site.

Several nationally established codes are there which you can take up. Among these three of them are occupy the top position in establishing welding codes for welder certification namely American Welding Society (AWS), the American Petroleum Institute (API), and the American Society of Mechanical Engineers (ASME). If you want to be a certified welder any of the agencies, you need to follow the specific code set forth in the organization's welding procedure specifications or WPS. These organizations are having different standards but they are usually very similar in the tests they give for welding certifications as well as their set codes.

Laser welding - The advanced welding technique

2010-07-27T02:15:00.001-07:00

Laser is the abbreviation of light amplification by stimulated emission of radiation and it emits light using the process of stimulated emission. Laser has extended itself in the process of welding where multiple metals are joined together. It penetrates deeply and minimizes the heat input and has a high power density. The two types of laser used are solid and gas state lasers, and the types of laser used are co2, ND YAG and diode laser. It is used in high volume application because of the capability of gas lasers and used in various industries. The laser beam welding is a quality type welding which welds smaller and thinner components with increased speed and it is also used for joining molded thermo plastics. Dual beam welding technique is a process that combines two high energy beams and it is more advantageous than single beam welding process.

Learn welding through virtual reality

2010-07-26T02:09:00.000-07:00

Plasma Cutting Technology:

2010-07-19T10:22:00.000-07:00

Do you require a cutting instrument for infrequent repair and preservation work? Have you newly embark on a fresh project that requires higher cutting volumes? Or, are you appear for a new option to your present automatic saw? All of these scenarios give huge reasons to examine plasma cutting. With the price of equipment on the refuse, smaller-sized, portable machinery flooding the marketplace and technology offering augmented reimbursement and easier usage -- it might be time to get a serious look at plasma for your cutting applications. The reimbursement of plasma cutting contains simplicity of use, superior quality cuts and quicker travel speeds.

In simplest terms, plasma cutting is superheated, dense air to ionize to shape a conductive gas. This gas conducts electrical energy as of the torch of the plasma cutter to the work part. This is completed throughout a conductive electrode and copper needle on the mechanism, which constrict the high speed gas causing a cyclone result. This provides power to the arc that melt and blows away the metal.

Power vision helmets

2010-07-13T02:37:00.000-07:00

Welding helmets are the protective gears to welders. It protects the eyes, face neck etc; in general it protects the sense organs. What is the use of it? Welding helmets are essential during the welding process since the welding process creates an electric arc and flames which are dangerous to the sense organs. So the welder should wear the quality helmet which gives him protection. Power vision helmets are categorized into three types such as strongman, fabricator and defender. Strongman helmet has the perfect clarity which allows to see weld pool. It has lithium battery whose life is excess of 5000 hrs and also solar assisted for increased battery life. It is used in pipeline industry, machine shops and in construction sites etc. Fabricator helmet also has the same features and it reduces night blindness. Defender type has four sensors while the former two has two sensors and its adjustable sensitivity allows for use at low amperages.

Spot welding- The Form of resistance welding

2010-07-12T00:05:00.000-07:00

Spot welding is a welding process in which the metals are joined due to the resistance of electric current flow. It is used to weld different types of sheet metal and used in making metal buckets, aluminum's and also used in making batteries. Resistance is a measure of how the object opposes an electric current. Tool holders and electrodes are the equipment used here. This welding usually occurs in three stages such as first the electrodes are brought into the contact and then current is applied and at last the current is removed. Automobile industries mostly use spot welding and it is an effective method for joining metal parts. Spot welding uses high electric current and heat, so it always better to use safety accessories for protection.

TIG Welding:

2010-07-09T16:42:00.000-07:00

TIG welders are intended for the Gas Tungsten Arc Welding method (GTAW), which is usually referred to as the Tungsten Inert Gas method (TIG welding). The TIG method derives the warmth for welding as of an electric arc recognized among a non-consumable tungsten electrode and the division to be welded. Filler metal, if used, is physically provided for into the weld puddle at what time TIG welding.

The TIG welding method requires an air- or water-cooled torch to hold the tungsten electrode and is linked to the TIG welder. The TIG welding method also requires an outside defensive gas, characteristically argon, helium, or a combination of the two to defend the melt metal and electrode from impressive contagion.

High excellence welds can be created by TIG welders. The TIG welding method too has all places welding ability and is brilliant on extremely thin equipment. In addition, a TIG welder makes welds that contain exceptional look and clean-up is quick and simple as there is no slag and fundamentally no splash.

Parameters of MIG welding:

2010-07-06T05:14:00.000-07:00

The rule of the MIG welding was developed present 50 years. An electrical arc is created among the piece and an electrode shaped by the cable (wire) that comes as of the torch, which is too an input field. An inert gas is injected throughout the torch to make a protective halo approximately the weld and get better quality.

Important parameters in the MIG welding are:

* speed wire feeder,
* distance from the torch to the sheet,
* voltage,
* the speed of the torch,
* the position of the torch: "push" or "pull"
* Skill and knowledge of the worker.

as well the speed and power supply wire which are adaptable on the position from MIG knobs, the additional parameters are managed straight by the worker throughout his actions.

These MIG welding parameters are able to have an effect on to a huge extent the quality of a weld, and have to be adjusted properly previous to soldering. An excellent knowledge of their effects on the weld is necessary to execute best setting according to your circumstances.

IMPACT OF ENGINEERING CONCEPTS IN WELDING

2010-06-28T00:16:00.000-07:00

What is engineering? Engineering is a discipline where we apply technical, scientific and mathematical knowledge to implement and to design some machines, devices and structures. The power equipments and machines we use in the welding industry are the inventions of engineering concepts. Plasma cutter the equipment which cuts different types of metals has the in built structure which is made of electrical components and the electrical energy is converted in mechanical energy during the operation of the machine. All other welding products such as mig, tig, wire feeders and water coolers are the child of engineering concepts. Silent diesel generators the alternative source of power supply is also an invention of engineering concepts. In generators the electrical energy is converted into mechanical energy. In welding torches the gas which flows is controlled by a gas valves is a mechanical engineering concept which follows some mechanics.

Underwater Welding Work Process:

2010-06-24T17:56:00.000-07:00

Underwater welding consists of more than a few methods used for repairing ships, pipelines and offshore oil platforms. Undersea welding splits into 2 major categories: wet and dry underwater welding. Both go down below hyperbaric welding, which is welding completed at augmented pressure, such as being undersea. Underwater welding used steel for repairs.

Dry undersea welding is completed by insertion a structure around the point to be welded. The structure is preserved approximately the weld point and gas fills the area shaped by this juncture. The welding then begins in the chamber. Dry undersea welding is careful to be very correct in its last product. Wet undersea welding uses water-resistant electrodes to provide power to the welding tools. Wet underwater welding is measured to be easier to start due to the lack of preparing the dry welding's chamber. Wet welding too allows for more liberty of movement by the welder.

Wet undersea welding has extra risks than dry undersea welding. One such danger to the welder is beginning electrocution. The equipment used must be insulated and power has to be correctly maintained. In adding to electrocution, welders have to be worried with diving issues and the probable build-up of oxygen and hydrogen gases, which know how to be explosive.

Spot Welder Parts:

2010-06-21T05:29:00.000-07:00

A spot welder normally has just a small number of parts. These include the electrodes which are most usually complete of an alloy metal similar to copper or silver. These electrodes require to be clamped on a sheet of metal to apply the current. This is complete by handler or tool holds which place the electrodes. These can be very lengthy arms that are attached to a machine or automaton which can shift the electrodes approximately a surface. The additional thing a spot welder has is a coolant. This is typically water or several additional type of combination depending on the application. Since a spot welder generates a lot of power it creates a lot of high temperature and so wants coolant.

Multi process units are the on spot and multi purpose units

2010-06-15T05:38:00.000-07:00

Due to busy schedule humans needed some equipment which serves as a multi purpose equipments. Especially industries needed these multi process equipments which benefits them. Welding industries uses multi process units to make their work easier. Multi process units are the compact and portable units which perform on spot repair and almost weld any metal. Multi process unit’s enables smooth and clean plasma cuts on any metals and used for all welding process such as tig, mig, arc welding and has plasma cutting features. Multi process units are low power consumption units with inverter design and have high duty cycle. Multi process units are used in general repairs, light fabrication and in some HVAC, and also enables easy verification of air pressure and warns the user when the duty cycle is exceeded. It enables changes of torches from tig to plasma and vice versa. A Multi process unit enables portable repairs and reduces the need of carrying more equipment.

Importance of plasma cutter reviews

2010-06-14T05:40:00.000-07:00

There are umpteen ways to cut metal but if you want to know the best option, it is always a plasma cutter. They are specially designed for cutting metals like stainless steel and aluminum and moreover it uses the latest technology to cut metals accurately. The main advantage is that the plasma cutters cut even the heavy metals effortlessly and within a short span of time. Earlier these tools were considered expensive but now with the gaining demand, the prices have also become reasonable. Only one drawback is that the machines make a lot of noise and it is better advised to wear hearing protection devices while using them.

When it comes to buying the machine, it is important to rely on the plasma cutter reviews. Through the reviews, you would know about the benefits as well as restraints of the system.

Importance of Plasma Cutting Safety:

2010-06-08T14:19:00.000-07:00

It would be a grave mistake to disregard the important of plasma cutting safety. Just because the plasma cutter is easy to use, that doesn’t make it appropriate for haphazard use. Here are some tips to keep you safe while operating one of these machines.

1.Never operate a plasma cutter in a wet environment. You must understand that the plasma cutter uses electricity to start and stay running. Its electrical circuit lies between the torch and the surface being cut. Anything that comes in contact with the object being cut becomes a part of that electrical circuit including water. Okay, especially water since water conducts electricity just like some metals do. So use a plasma cutter in dry environments only.

2.Do not retrieve cut pieces of metal while you’re cutting. Do not remove work pieces while the grand cable is attached. And do not remove a ground clamp while cutting. Doing so places you at high risk for electrocution. For this very reason, insulated boots and gloves are required equipment in any serious place of business.

3.Make sure the ground cable is well secured onto the piece that’s being cut (NOT the piece that will fall off). Arcing near the ground clamp is a sign that the clamp is damaged, unsafe, and needs replacing. Failing to make a safe and secure connection is a sure-fire way to experience electrical shock. The ground clamp must always remain secured prior to releasing a plasma cutter's trigger.

4.Don't use a plasma cutter without proper eye protection. Eye protection isn't just for shielding flying debris. It’s also for shielding against burning. Plasma cutters produce highly intense ultraviolet and infrared waves that can burn the retina, cause cataracts, and damage the skin even if proper precautions aren’t taken.

5.Keep your plasma cutter away from flammable materials. Don’t store or use your cutter near gasoline or other combustible solutions.

6.If you use a heavy duty plasma cutter - that is, one with a excessive noise level, wear ear protection as well.

7.Use a plasma cutter in a well ventilated area. Plasma cutters melt metal and the gases released are toxic.

Terms and Definitions Reminder about Welding:

2010-05-28T22:07:00.000-07:00

Automatic Welding is performed with automatic equipment that requires no controls adjustment by an operator.

Braze is the joint resulting by heating an assembly to the brazing temperature using a filler metal whose liquidus is higher than 450 0C (840 0F) and lower than the solidus of the base metal.

How does Peak current and Base current affect the properties of weldments?

2010-05-25T02:38:00.000-07:00

The current levels are only two of the parameters determining weld quality. To understand parameters function, the period can be broken down into several parts:

1. Ramp up rate increase stiffens the arc, reducing the arc column size and increasing the propelling force throwing molten drops detached from the electrode,
2. Overshoot, an instantaneous current increase above the peak current level, necessary to overcome the influence of inductance, variable with cable length,
3. Peak current level directly controls penetration: the higher the peak current, the deeper the penetration,
4. Peak Time or Peak Duration influences the width of the bead shape,
5. Tail-out drop time, speed of change and shape controls energy addition to the molten droplet, directly influencing puddle fluidity and penetration,
6. Sudden current drop down to background level, reduces the tendency for fine droplet spatter,
7. Background Current, the low-level current needed to maintain the arc,
8. Frequency or Repetition Rate shapes the weld bead by narrowing the arc cone with increased frequency.

Arc welding process and its equipments

2010-05-21T05:48:00.000-07:00

Welding is regularly used for the permutation processes i.e. arc, resistance, laser, electron beam, stud and orbital welding.

Weld controllers are necessary to help the processes used by these tools. Welding equipments also work as aid to welding control source. There are also wide-ranging system to cutting machine, torch, feeders, cables, robots and feeders.

Arc welding process and welding machines

Arc welding is utilizing welding power supply to produce an electric arc between the base material and an electrode, for melting the metals at welding point. Arc welding equipments can use and direct current or alternating current, and consumable or non-consumable electrodes. Shielding gas guards welding region using some inert or semi-inert gas and evaporate wadding material. The process of arc welding is broadly known for low capital and running costs.

MIG and TIG welding are the two common specifications of Arc Welding. MIG is also acronym as MAG (metal active gas welding) and known as one of the mostly popular arc welding process. MIG welding equipments uses in different kinds of gas like pure carbon dioxide, argon gas and some time merge of both to complete the process.

Highlights On Mig Welding

2010-05-20T05:52:00.000-07:00

Feed welding is the other popular name for Mig (Metal insert gas) welding. Other popular names for this weld technique in weld industry are like Gas Metal Arc Welding (GMAW or Metal Active Gas (MAG). It is one of the fastest and simplest techniques of weld.

The method of welding is semi-automatic or automatic. With the helping of welding gun wire electrode and a shielding gas is fed into it continuously. Apart from this Argon gas is also conceded in welding gun along with the wire electrode. This is done so as to achieve the desired results. This technique is mostly employed in high production and welding operations.

MIG welding operation can be carried on metals such as stainless steel, copper, carbon steel, and aluminum. All these metals can be weld in this process and moreover it can be performed in every position with the help of shielding gas, electrode, and welding conditions. This weld technique is popular in automobile industries. The gas which is fed in it acts as a shield agent protecting the weld zones from the contaminants of air borne. While performing this weld operation welder has to follow safety tips to protect him and others too.

How to use Electrodes in Welding Process

2010-05-17T03:13:00.000-07:00

Electrodes are used in welding to transmit electrical energy to the metal that requests to be welded. Welding electrodes have change since the process of welding was industrial with carbon arc welding, but different other evolutionary processes, the former electrode types are still in use today.

Carbon Electrodes
Welding in progress with the carbon arc electrodes. Carbon electrodes are detained in a stinger and are the softest kind of welding electrode. This has difficulty that has ended carbon electrodes the least common type of electrode used today. The yielding make-up of carbon electrodes leads to weld contamination and a high use rate.

Resistance Electrodes
Resistance welding spot welding uses two copper electrodes and no inert gas to combine metals jointly. Copper electrodes are yielding, other than last longer then carbon electrodes. With each resistance weld a small quantity of the copper electrode is put down on the work piece.

Stick Welding
Stick welding electrodes are containing two components. The center rod conducts the electricity to the weld exterior, but dissimilar other electrodes, the interior rod are the filler rod used to fill the weld gap. The center filler rod/electrode is bounded by a hard outer coating, when the stick electrode is heated the hard coating melts and seals the weld from contamination.

Tungsten electrodes
Tungsten electrodes are the hardest of all welding electrodes and this categorize them as a non-consumable. Little or no tungsten electrode is set down into the weld, except by welder error. The hard nature of tungsten is used to its fullest benefit in TIG welding.

Tungsten inert gas (TIG) welding has a fast heat cycle and is used in state of affairs that require a solid sealed weld.

History of Waterjet Cutting

2010-05-12T06:27:00.000-07:00

Waterjet cutting can be traced back to hydraulic mining of coal in the Soviet Union and New Zealand. Water was collected from streams and aimed to wash over a blasted rock face carrying away the loose coal and rock. Th is method of mining was redeveloped in South African gold mines to remove blasted rock from the work area into a collection drift or tunnel. In the California Gold Country between 1853-1886, pressurized water was first used to excavate soft gold rock from the mining surfaces. The pressurized water allowed the miner to stand further back from the face being washed. This was safer because there was less danger of being covered by a collapsing wall of blasted rock. By early 1900s this method of mining had re ached Prussia and Russia. In these two countries the pressurized water was used to wash blasted coal away.

In the 1930s it was Russia that made the first attempt at actually cutting the rock with the pressurized water. A water cannon was used to generate a pressure of 7000 Bars.

In the 1970s technology was developed in the USA that was capable of creating a 40,000 Bar pressure. Most of the waterjet mining growth after this involved combining a drill with the waterjet. In 1972 Professor Norman Franz of Michigan worked with McCartney Manufacturing Company to install the first industrial waterjet cutter. The equipment was installed in Alton Boxboard. Flow industries also began to market industrial waterjet cutting equipment. It was Flow Industries who added sand to a pressurized cleaning system to give metal a white finish. After this it was demonstrated that abrasive waterjet systems could cut through metal and ceramics. From here the waterjet cutting industry took off.

How TiG welding procedures are used for Mild steel

2010-05-07T03:41:00.000-07:00

Mild steel is a steel alloy to facilitate has a low percentage of carbon, normally 0.3 percent or less. For this basis, mild steel is also called low-carbon steel. It is enormously common in manufacture because it is inexpensive compare with other steel alloys and is simple to weld. Mild steel can be welded with tungsten inert gas (TIG) welding methods, and the result is a clean and precise weld.

For the reason that the TIG welding process uses a tungsten electrode that is not consumed, a divide welding rod or wire is used as filler material for welding mild steel.

Steel require a sharper electrode point to concentrate the heat at the weld seam, as different to aluminum and other metals, in which heat dissipate more rapidly. The diameter of the electrode should be approximately half the thickness of the parts to be welded. The welding machine must be set for DC current and directly polarity, through the electrode having the negative charge.

General view about Tungsten Electrode

2010-05-06T04:02:00.000-07:00

Electrodes are generally accessible in pure tungsten or tungsten with oxide additions of thorium, zirconium, and lanthanum.

Oxide additions decrease the electron emission energy of the electrode:

pure tungsten (5.36 eV)

thoriated tungsten (2.62 eV)

For AC welding pure tungsten or zirconiated tungsten are used, whereas for DC welding thoriated tungsten or tungsten electrodes with rare earth oxide additions are optional (thorium is radioactive).

Thoriated electrodes are not optional for AC welding; since the electrode tip does not form the necessary hemispherical bulb thus gives an unstable arc and unsatisfactory cleaning action. For DC welding thoriated electrodes offer for a stable arc, improved electrode life span, greater current carrying capability along with better arc ignition.

All bout TIG Cold Wire Feeders

2010-05-04T02:36:00.001-07:00

A semi-automatic, cold wire-feed machine is a productivity-enhancing tool that's built to improve TIG weld quality and effectiveness, lower costs and permit for quick and consistent filler metal confirmation.

Increase TIG welding productivity by get rid of time-consuming arc stops-and-starts regular with cut-length-rod.

Condense process variables with continuous spooled-wire which provides quick and consistent filler metal confirmation eliminating the potential weld quality problems associated with unidentified welding alloys.

Choosing a welding kit

2010-04-27T22:15:00.000-07:00

When employers select work equipment, the Provision and Use of Work Equipment Regulations 1998 require them to consider the risks posed to the health and safety of people using that equipment. This includes ergonomic risks.

When selecting a welding set, consider the effect poor equipment handling might have:

■personal suffering caused by injuries;
■the financial burden of sickness absence;
■reduced productivity;
■increased insurance premiums; and
■the welder being unable to return to this type of work, which would affect their potential future earnings.

Reducing injuries caused by handling welding equipment will benefit everybody.
Here are some ergonomic design features to look for when deciding between welding sets with the same power output:
■Does the set have to be carried? Consider controlled pushing or pulling of the load instead of lifting and carrying.
■How easily can the load be grasped?

Health and Safety Executive
■Are the handles suitable?
■Can the load be held close to the body (avoid sharp corners, jagged edges, rough surfaces etc)?
■Is it well balanced?

Other considerations include:
■handle orientation;
■ease of pushing/pulling;
■axle types;
■size of wheels;
■wear and maintenance of wheels/tyres;
■effect of torch, wire feed, hoses, gas bottles etc on the handling characteristics of the welding set.

The checklist in this leaflet will help you select the right welding set.
