TIG welding, or Gas Tungsten Arc Welding (GTAW), is a welding method that utilizes a non-consumable tungsten electrode to create an electric arc. This electric arc generates intense heat, which, in turn, melts the base metal, creating a weld pool. TIG welding is known for its exceptional precision and control.

The Radioactivity Problem. The Thorium used in 2% thoriated tungsten is a radioactive element and therefore can be dangerous to the health of those exposed to it and to the environment. It is an alpha emitter, however when it is inside a tungsten electrode rod, it is enclosed in a tungsten matrix and so there is little radiation emitted externally.
