WELDING TECHNIQUE AND MAINTENANCE
1.1 TIG 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.
