GTAW, also known as tungsten inert gas (TIG) welding, is a type of arc welding which produces the weld using a non-consumable tungsten electrode.See all results for this questionsp.info What is the best welding temperature for stainless steel?Flat to slightly convex weld beads are preferred. When welding alloys which do not contain ferrite, a lower interpass temperature is preferred which lowers thermal stresses. A maximum interpass temperature of 300°F (150°C) is recommended. Duplex alloys are quite different from standard stainless steels.See all results for this question
