Tungsten insert gas welding is popularly also known as Gas tungsten arc welding (GTAW). You can protect the welding area from getting contaminated with the help of shielding gas which is insert gas.
Tig welding is more widely used to weld the thin sections of stainless steel and non ferrous metals such as aluminum magnesium and copper alloys. This welding process grants the operator to have a greater control over the weld when compared with other welding procedures such as shielded metal arc welding and gas metal arc welding. Though this welding process is very slow but it provides high quality welds.
Tig welding can be carried on all positions - flat, horizontal, vertical or overhead. Perfect for roll cages and inside confined areas too. Filler rod is one of the most important aspects in this welding process.
Equipments required for tungsten insert gas welding process are welding torch utilizing a non consumable tungsten electrode, a constant-current welding power supply, and a shielding gas source.
During this welding process an arc is formed between a non-consumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately. Welders have to be careful while doing this procedure.
