All About Tungsten in TIG Welding: Types, Selection and Use
WEBOct 5, 2022 — Pure tungsten was favored for aluminum and magnesium, and 2% thoriated tungsten was used for everything else. While these worked well for generations, research and development led to a broad range of tungsten electrodes, each with unique properties.
Welding with non-consumable thoriated tungsten electrodes
WEBOct 31, 2014 — Tungsten inert gas shielded welding (TIG), also known as gas tungesten arc wedling (GTAW) is a process in which a non-consumable tungsten electrode forms one of the poles of an electric arc. Tungsten is used because it can withstand very high temperatures with minimal melting or erosion, i.e. “non-consumable”.
