What is TIG Welding? | FAQs | Praxair Distribution, Inc.

TIG Welding

TIG Welding is shorthand for Tungsten Inert Gas Welding. It is also known as GTAW or Gas Tungsten Arc Welding. TIG Welding is a welding process which uses a non-consumable tungsten electrode to produce the arc with the work pieces. The electric arc between the tungsten electrode and the work pieces heats the work pieces and a filler metal is added to the arc which causes the pieces to fuse together. The welder feeds the welding rod manually with their off hand and the welding gun blows a shielding gas to protect the metal fusion from contaminants in air and create the precise desired chemical reaction.

TIG Welding is most commonly used in Stainless Steel and Aluminum applications.
