OK Tubrod 15.11

A rutile, all-positional, flux-cored, tubular wire containing 2.5 Ni for the welding of mild and medium tensile steels where good notch toughness down to -50°C is required. Extra productivity is available using the spray transfer mode when compared with the traditional basic types using short arc for vertical and overhead welding. All types of fabrication application involving mild and medium tensile steels with a min. yield strength of 510 MPa. This includes shipbuilding and offshore fabrication. Shielding gas: Ar + 20% CO2.
