This disclosure relates generally to Gas Metal Arc Welding (GMAW) and, more specifically, to Metal-cored Arc Welding (MCAW) of mill scaled steel workpieces. A metal-cored welding wire, including a sheath and a core, capable of welding mill scaled workpieces without prior descaling is disclosed. The metal-cored welding wire has a sulfur source that occupies between approximately 0.04% and approximately 0.18% of the weight of the metal-cored welding wire, and has a cellulose source that occupies between approximately 0.09% and approximately 0.54% of the weight of the metal-cored welding wire.
