Applications
The GTAW process and can be applied to a wide variety of ferrous (iron-containing) and non-ferrous (non iron-containing) metals. It can be used to weld materials in AC and DC polarities, making it an extremely versatile discipline of welding. Materials able to be welded via this process include, but are not limited to, aluminum, magnesium, and copper in AC polarity, and steel, stainless steel, titanium, and nickel alloys in DC polarity. TIG welding can also be used to join dissimilar metals, such as steel to stainless steel, and stainless steel to nickel alloys when proper welding processes and filler rod are used.
