Gas-Tungsten Arc Welding. The process is used with gas protection and without the application of pressure. The reason for this is that shielding gas is used in place of flux.
Conventional welding arc welding (i) shielded metal arc welding (smaw), (ii) gas metal arc welding (gmaw), (iii) flux cored arc welding (fcaw), (iv)gas tungsten arc welding (gtaw) or tungsten inert gas (tig) welding (v) submerged arc welding (saw), (vi) plasma arc welding, (vii) carbon.
D connect work cable to the work as close to the welding area as practical to prevent. In the tig process the arc is formed between a pointed tungsten electrode and the workpiece in an inert atmosphere of argon or helium. Learn vocabulary, terms and more with flashcards, games and other study tools. Tig weldings proper name is gas tungsten arc welding or gtaw. 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. Tungsten inert gas heliarc:(heliarc® was the trade name given to the process by linde's when it was introduced decades ago.) Gas tungsten arc welding (gtaw) is a widely used process. Inert gases such as argon or helium are used to protect the area being welded from contamination and most, although not all, welding applications. It often requires adding filler metals to produce desired welds. So let's start with the definition first. The gas tungsten arc welding (gtaw) is also known as tig welding (tungsten inert gas).
