The use of thoriated tungsten electrodes
Introduction. Tungsten electrodes are used when arc welding with the Tungsten Inert gas (TIG) process or when plasma welding. In both processes the electrode, arc and weld pool are protected from atmospheric contamination by an inert gas. A tungsten electrode is used because it can withstand very high temperatures with minimal melting or erosion.

Ground and Polished Tungsten Electrodes for High-Purity Welding
One of the most important factors in any high-purity gas tungsten arc welding (GTAW) project is the quality of the tungsten electrode used. If the tungsten is not sufficiently pure, the weld may need to be scrapped and redone, which lowers productivity and increases material costs. High-purity, high-quality tungsten electrodes create reliable ...

Gas Tungsten Arc Welding (GTAW or TIG)
An inert shielding gas protects the molten weld pool and the nonconsumable tungsten electrode. The process is often referred to as TIG, short for tungsten inert gas. Filler materials are specified through the same methods as for GMAW. The process may use direct current electrode positive, direct current electrode negative or alternating current.
