Gas tungsten arc welding or GTAW is the same as tungsten inert gas or TIG welding. It is also an arc welding process. Here a non-consumable electrode is used. And most importantly - the electrode is made of tungsten. And this electrode helps to produce the weld. The weld area is protected from atmospheric contamination or oxidation by usually an inert gas. This shielding gas is generally
