TIG stands for Tungsten Inert Gas and is technically called Gas Tungsten Arc Welding or GTAW. The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. The tungsten and weld puddle are protected and cooled with an inert gas, typically argon. TIG welding is similar to oxy-acetylene welding in that you use a filler material for build-up or reinforcement.
TIG Welding can be done in any welding position and in manual, semiautomatic and automatic modes. TIG Welding can be used to weld almost all metals and metal alloys and is a particularly effective and economic way for welding light gauge metals (under 3mm thickness) and for welding metals difficult to weld with the conventional welding process. Such metals include Aluminium and aluminium alloys, Copper and copper alloys, Nickel and nickel alloys, Low alloy steel and carbon steels and Joining carbon and alloy steels.
