38+ Gas Tungsten Arc Welding (Gtaw) Images. 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 process is used with gas protection and without the application of pressure.
7 1 The Gas Tungsten Arc Welding Station Halverson Cts from www.halversoncts.com The process is used with gas protection and without the application of pressure. Tig has played a major role in. Tig stands for tungsten inert gas.
Guidelines to gas tungsten arc welding.
This is the name the american welding society and other welding organizations refer to this process on their welding procedures. Is due to russell meredith, who perfected this process in 1941 1. However, there is a risk that the electrode may stick to the surface and cause a tungsten inclusion in the weld. The electrode, the arc and the area surrounding the molten weld puddle are protected from the atmosphere by an inert gas shield.
