OK Autrod 13.28
GMAW
A copper-coated, low-alloyed, 2.5%Ni electrode for the GMAW of low-alloyed and low-temperature steels for applications such as vessels, pipes and in offshore industry. Also for welding steels where good impact strength at lower temperature (-20°C) is required. OK Autrod 13.28 is usually welded with Ar/20CO2 as the shielding gas. The minimum values for the mechanical properties are given in the post-weld, heat-treated condition.
