Gas Tungsten Arc Welding (GTAW/TIG)

Gas Tungsten Arc Welding (GTAW) is also known as Tungsten Inert Gas Welding (TIG Welding). It is an arc welding process that uses a non-consumable electrode made up of Tungsten (or alloy of tungsten). Arc is generated between the tungsten electrode and work piece to establish the weld pool. Inert gas (Argon or Helium) is used to shield the molten weld pool during welding. Additional filler metal may be added….
