OK Autrod 12.64

OK Autrod 12.64 is a copper-coated, Mn-Si-alloyed G4Si1/ER70S-6 solid wire for the GMAW of non-alloyed steels, as used in general construction, automotive components, pressure vessel fabrication and shipbuilding. It has a slightly higher manganese and silicon content than OK Autrod 12.50 to increase the weld metal strength. This also promotes low sensitivity to surface impurities and contributes to smooth, sound welds. The wire can be used with both Ar/CO2 mixed gas and pure CO2 shielding gas
