Welding electrode wire, Cu coated with the addition of deoxidizing agents Mn and Si, designed for semi automatic welding under the protective atmosphere of CO2 (MAGC) or mixtures M21-80% Ar + 20% CO2 (MAGM). The increased content of Mn gives higher weld strength, higher resistance of the weld to surface contamination and better impact strength when compared to G6. It is used for welding of unalloyed construction steels, boiler steels, shipbuilding steels, and low alloyed, general purpose, C-Mn steels of increased strength. This wire is highly recommended for the Pipe Industry with high silicon (1%) for good fluidity and very less spatter. Welding electrode wire can be in the range of 1.20 to 1.60mm for fabrication and 2.50 to 3.15mm for the Pipe manufacturers.
