A triple deoxidized copper-coated rod designed for GTAW of mild and fine grained structural and pressure vessel steels as well as shipbuilding steels. The rod is capable of producing high quality welds in semi-killed and rimmed steel as well as steel of various carbon levels. Because of added deoxidants, Al-Ti-Zr, Tigrod 12.62 can also be used for welding steels with a rusty or dirty surface without any sacrifice of weld quality.
