A triple deoxidised copper-coated rod designed for GTAW of mild and fine-grained structural and pressure vessel steels as well as shipbuilding steels. The rod can produce 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.
