Gas Metal Arc Welding of Pure Tungsten Electrode

Gas Metal Arc Welding of Pure Tungsten Electrode Picture

Tungsten Inert Gas (TIG) or Gas Tungsten Arc (GTA) welding is the arc welding process in which arc is generated between non consumable tungsten electrode and workpiece. The tungsten electrode and the weld pool are shielded by an inert gas normally argon and helium. This is also available in pure tungsten electrode.

It is a known fact that one of the strongest methods of joining metal is through fusion by arc welding, so is used in pure tungsten electrode. In this welding process, an electric current allows an electric arc to melt two metal pieces. Gas Tungsten Arc Welding (GTAW) is referred to in professional circles as Tungsten Inert Gas (TIG) welding. This is an arc welding process that uses a tungsten electrode to create the weld.

Arc welding is the most common technique used. It is the first lesson for welding. Instead of using a gas torch, high voltage electricity is to be used. In arc welding, a spark/arc is able to melt a metal & form a weld.
