Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW), is an arc welding process in which a weld is produced using a non-wearing tungsten electrode. Using an inert gas shield instead of slag to protect the weld pool, the process was a very attractive substitute for gas welding and manual arc welding. TIG has played a major role in making aluminium acceptable for high-quality welding and structural applications.
