Gas Tungsten Arc Welding (GTAW)
This process, also known as Tungsten Inert Gas (TIG) welding, is similar to MIG welding. However, the only difference is that pieces of metal are fused together using a 'tungsten' electrode. It makes use of inert gases such as argon, helium, or argon-helium mixture in order to weld reactive metals like aluminum and magnesium.
