4.06 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. Shield-
ing 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.
