How does gas tungsten arc welding ( GTAW ) work?


How does gas tungsten arc welding ( GTAW ) work?

Gas tungsten arc welding (GTAW) is an electric arc welding process that produces an arc between a nonconsumable electrode and the work to be welded. The weld is shielded from the atmosphere by a shielding gas that forms an envelope around the weld area (see Figure 1). Figure 1:See all results for this questionsp.info What kind of gas is used in arc welding?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.
