The use of thoriated tungsten electrodes TWI

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.

Gas Tungsten Arc Welding (TIG) waybuilder.net

It is virtually impossible to vaporize a tungsten electrode during welding, provided you use the electrode within the current-carrying capacity range for its specific type and diameter, with sufficient inert shielding gas. Tungsten retains its hardness, even at red heat. There are several types of electrodes for gas tungsten arc welding.
