Gas Tungsten Arc Welding. The process is used with gas protection and without the application of pressure. Tungsten inert gas welding process also called as gas tungsten arc welding is named so because it uses.
In this process, coalescence of metals is produced by heating with an arc between the base metal and a nonconsumable tungsten electrode.
Gas tungsten arc welding (gtaw) is an electric arc welding process that produces an arc between a nonconsumable electrode and the work to be welded. Tungsten arc welding (gtaw), also known as tungsten inert gas (tig) welding is a process that produces an electric arc maintained between a non consumable tungsten electrode and the part to be welded. This process can be used with or without the addition of filler metal. It often requires adding filler metals to produce desired welds. D do not weld where the atmosphere may contain flammable dust, gas, or liquid vapors (such as gasoline). Typical other uses for tungsten. Tungsten inert gas heliarc:(heliarc® was the trade name given to the process by linde's when it was introduced decades ago.) In the tig process the arc is formed between a pointed tungsten electrode and the workpiece in an inert atmosphere of argon or helium. It is similar to form of arc welding process. If you are just a beginner tig welder, it is normal to feel a bit intimidated by the different types of tungsten out there. The tungsten electrode is not used during this welding operation, a constant and stable arc gap is maintained at a constant current level.
