Our G4Si1-grade copper coated double-deoxidised mild steel MIG wire for welding unalloyed and low-alloyed mild and medium tensile steels. Precision layer-wound with a high-quality copper finish for improved feeding. Suitable for use in general fabrication, construction, tanks and boilers, agricultural, auto-body and repair & maintenance applications.
DESCRIPTION
Copper coated double-deoxidised mild steel MIG wire, with increased silicon and manganese content, for welding unalloyed and low-alloyed mild and medium tensile steels requiring good impact toughness down to -20°C. Manufactured with a high-quality copper finish for improved feeding. Precision layer wound. Weldability SG3 typically provides a higher ultimate tensile strength over standard Weldability A18.
WELDING POSITIONS
Suitable for use in general fabrication, construction, ship building, tanks and boilers, repair and auto-body applications. Comprises increased manganese and silicon to provide improved mechanical properties.
