OK Flux 10.74 is an agglomerated, basic flux designed primarily for multi-wire procedures in the production of longitudinal welded line pipes. The flux alloys some Si and Mn to the weld metal and works equally well on DC and AC current. It offers best weldability on SAW processes with at least 3 independent welding wires. OK Flux 10.74 produces a low bead profile in longitudinal line pipe welding at high welding speeds. A low profile without peaks means cost saving in the later pipe coating operation, since the coating thickness can be reduced. With various wires, OK Flux 10.74 is suited for all pipe steels. In combination with the Ti-B micro alloyed wire OK Autrod 13.64 toughness values are increased to an outstanding level. Due to the careful metallurgical design OK Flux 10.74 produces a weld metal free of hard spots.
