OK Autrod 12.50
GMAW
A non-copper-coated, manganese-silicon bearing electrode for the GMAW of unalloyed steels, such as general structural steels with a minimum tensile strength of 530 MPa, and for fine-grained carbon-manganese steels for the same purpose with a minimum yield strength of 420 MPa. OK Autrod 12.50 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.
Diameter 2.0 mm is used for SAW in combination with OK Flux 10.83 for high speed travel speeds in butt welding of thin plate. SAW classification according to AWS A5.17: EH11K.
