GTAW Welding

The full name of GTAW welding is Gas Tungsten Arc Welding, also call inert gas argon arc welding, namely TIG.

The electrode of GTAW is tungsten electrode or tungsten alloy, because tungsten has the highest melting point of all metal, approximately 6170℉ (3410 ℃). Tungsten and tungsten alloy electrode technical requirements established by the American Welding Society includes eight standard tungsten. Tungsten has two supply states, chemical cleaning or polishing state. Chemical cleaning refers to the state that the tungsten has been drown or forged by chemically clean. Polishing means a kind of tungsten that has a uniform diameter and smooth surface after grinding. Tungsten surface of polished state is very smoothing with perfectly cylindrical, and therefore it can be more stably to delivery heat to tungsten clip. The range of tungsten diameter is 0.20 ~ 0.25in (0.5 ~ 6.4mm), length is 3 ~ 24in (76 ~ 610mm).
