Taxonomy: Gas Tungsten Arc Welding


Gas tungsten arc welding is a welding process that uses a nonconsumable tungsten electrode and a shielding gas to join metals together.


Overview of Process

This process involves causing a spark between a nonconsumable tungsten electrode and a metal surface, which causes the surface to melt and, upon cooling, form a connection between pieces of metal. An inert shielding gas (such as argon or helium) is used to prevent atmospheric contamination of the surface. Gas tungsten arc welding is a highly-effective welding technique for thinner pieces of metal, and has the advantage of using a nonconsumable electrode.
