different types of welding machine
Types Of Welding Machines. Welder machines come in all shapes and sizes from the small home workshop welder to industrial welding machines used for car manufacture and specialized industries.
Tig welding machines. â More specialized than mig welders tig machines are used for precision work and can weld more types of metal than any other process. Metals suitable to tig weld are stainless steel, mild steel, aluminum,copper, bronze, brass, gold, magnesium, chromoly, and nickel alloys.
1 Shielded metal arc welding (SMAW) - also known as stick welding or electric welding, uses an electrode that has flux, the protectant for the puddle, around it. 2  The electrode holder holds the electrode as it slowly melts away. 3  Slag protects the weld puddle from atmospheric contamination.
Flux-Cored Arc Welding - (FCAW). Flux-cored Arc Welding is a welding process similar to GMAW, in that it uses a continuously fed electrode, but uses a tubular wire filled with flux instead of a solid wire. There are two types of flux-cored wire, self-shielded and dual shield.
1 Gas metal arc welding (GMAW) - commonly termed MIG (metal, inert gas), uses a wire feeding gun that feeds wire at an adjustable speed and flows an argon-based shielding gas or a mix of argon and carbon dioxide (CO 2) over the weld puddle to protect it from atmospheric contamination.
TIG-Gas Tungsten Arc Welding (GTAW). Gas Tungsten Arc Welding, commonly called TIG or Heliarc, is a welding process that uses a non-consumable tungsten electrode to heat the base metal and to create a molten weld puddle.
