What exactly is gas shielded arc welding?
Gas shielded arc welding is therefore classed as a fusion welding process. Shielding gases are used to prevent the weld pool of the weld seam from chemically reacting with the surrounding atmosphere, whereby the arc and the weld pool are enveloped in a protective shroud. The required properties of the gas vary depending on
Gas shielded arc welding processes (TIG/MIG/MAG)
Tungsten inert gas welding (TIG) is an arc welding process, which uses a non-consumable tungsten electrode, shrouded by a protective atmosphere of inert gas, such as argon or helium. The extra weld metal can be provided by a separate filler rod if necessary. A direct current is used, with the electrode negative, to avoid overheating and
