OK Autrod 12.64
GMAW

A copper-coated, manganese-silicon-alloyed electrode for GMAW. Compared with OK Autrod 12.51, OK Autrod 12.64 has a slightly higher silicon and manganese content, which increases the yield stress and the tensile strength of the weld metal if it is welded with CO2 as the shielding gas. The high silicon content promotes low sensitivity to surface impurities and contributes to smooth, sound welds. OK Autrod 12.64 can be welded with Ar/20CO2 or pure CO2 as the shielding gas. The mechanical properties quoted here are welded with Ar/20CO2 as the shielding gas.
