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

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.

Welding Project Ideas:

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.

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

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):

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.

Welding & Cutting Safety Tips:

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.

How to get a welding certification

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

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

Generally people are afraid to learn welding since it is the process which deals with heat and flames. Especially women's don't learn welding and there is a say that they are not suitable for welding. Don't worry you can also learn welding and can become a successful welder. Virtual reality is a term which brings the real world to you in terms of computer simulated environment, but the thing you see through this is not a real one, it is an imaginary one. An arrangement is made through which users can interact with the virtual environment through computer inputs. You can learn welding through this process and it makes you the feel as if you are working in the welding industry, but it is an imaginary one. An arc+ welding simulator is used which enables you to handle a real time 3d welds with advanced characteristics. The advantages are, you can handle welding rods and welding guns with good control and it removes your fear to welding heat and flames.
