SG3 G4Si1 is a copper coated gas metal arc welding soild wire, it is particularly designed for semi-automatic and full- automatic GMAW applications. SG3 welding wire is suitable for GMA welding of un-alloyed stuctural steels with a tensile strength up to 540 N/MM2, ship plates and fine-grained C-Mn steels. It gives high strength weld metal at working temperatures varying between -50°C and 450°C. It contains higher Si and Mn than SG2 G3Si1 welding wire. Increased silicon improves wettability.
