What is TIG Welding?
Tungsten Inert Gas (TIG) welding is a highly sophisticated welding process that is used to join a variety of metals. It requires the use of shielding gas — most commonly pure argon or argon mixed with helium. TIG welding is unique because there is no physical contact between the electrode and the metal pieces being joined together. Instead, the electrode and metals are connected by an electrical arc. As a result, the arc is stable, which produces clean welds.
How Does TIG Welding Work?
TIG welding uses both direct currents (DC) and alternating currents (AC) depending on the metals being joined. TIG welding works by melting a base metal with an electrical arc formed between a tungsten electrode and a grounded metal. A tungsten electrode has a much higher melting point than more common metals such as steel, so it can tolerate higher temperatures and act as a connector between the metals and the electrical arc used to melt them.
Where is TIG Welding Used?
TIG Welding is most often used when joining metals like stainless steel, aluminum, and magnesium. One of the benefits of TIG Welding is that it allows the welder to maintain complete control over the heat input and welding arc, resulting in a more precise weld. TIG welding is helpful in the production of bike frames, fenders, door handles, and more.
