Gas Metal Arc Welding - Lincoln Electric
www.lincolnelectric.comGas Metal Arc Welding (GMAW), by definition, is an arc welding process which produces the coalescence of metals by heating them with an arc between a con-tinuously fed filler metal electrode and the work. The process uses shielding from an externally supplied gas to protect the molten weld pool. The application
