Abstract
Penetration-enhanced gas tungsten arc welding (GTAW) processes have been referred to variously as flux tungsten inert gas (TIG), A-TIG, and GTAW with a penetration-enhancing compound. This article provides a discussion on the principles of operation, advantages, disadvantages, procedures, and applications of GTAW. It also includes information on the equipment used and health and safety issues associated with GTAW.
