4.03 TIG (GTAW) Basic Welding Technique
Gas Tungsten Arc Welding (GTAW) or TIG (Tungsten Inert Gas) as it is commonly referred to, is a welding
process in which fusion is produced by an electric arc that is established between a single tungsten (non-
consumable) electrode and the work piece. Shielding is obtained from a welding grade shielding gas or welding
grade shielding gas mixture which is generally Argon based. A filler metal may also be added manually in some
circumstances depending on the welding application.
