(Tungsten Inert Gas) method, but in both instances the internal surfaces must also be purged with an inert gas such as
tungsten or just tungsten. In the first case (including the presence of molybdenum), the recycling process is completed by a further step involving the removal of phosphorus and arsenic. Recovery of both molybdenum and tungsten from spent catalysts involves a combination of pyrometallurgical and hydrometallurgical processes (see Figure 3).
Tungsten Inert Gas Welding. Gas tungsten arc welding (GTAW), also known as T ungsten Inert Gas (TIG) welding became an overnight success in the 1940s for joining magnesium and aluminium. Using an inert gas shield instead of a slag to protect the weldpool, the process was a highly attractive replacement for gas and manual metal arc welding.
