Advantages of SAW (Submerged Arc Welding):

-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)

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.

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:

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:

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?

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:

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?

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.
