Gas tungsten are welding (GTAW) , also know as Tungsten inert gas welding (TIG). Filler metal is bare wire rod. The molten metal was produced by tungsten electrode. The weld pool are protected from oxidation or atmosphere by inert shield gas that make GTAW has high quality weld than other process for steel, stainless steel, aluminum and Nickel alloy.
