However, alternating current or constant current systems are also used. A constant voltage Direct Current (DC) is commonly used in gas metal arc welding (GMAW). A gas known as shielding gas is fed through the welding gun enabling the workpiece to be shielded from air contamination. This electric arc melts the metal being welded and the wire and welds both metals together. Metal Inert Gas (MIG) Welding uses a consumable wire electrode to create an electric arc between it and the metal being welded. GMAW is considered a good choice because of its excellent finish. Traditionally, TIG and MIG welding have been the manufactoring process of choice for welders. It is enabling the two to melt and weld together. This creates an arc heating both the electrode and the workpiece metal. Gas metal arc welding (GMAW) refers to welding which requires a current from an electrode. It gets in comparison with Laser Beam Welding, a new welding method that is industrialized since the late eighties and has become a common practice in the automotive industry as well as in the production of pipes for liquids. The well-known Gas Metal Arc Welding was developed and is in use since the early nineteenth century. Certificates, Declarations, Datasheets and Brochures. ![]()
