OK Flux 10.71      SAW Type Basic OK Flux 10.71 is a basic agglomerated, slightly Si- and Mn-alloying, flux for submerged arc welding, specially designed for fillet welding and for single and multipass butt welding of mild, medium and high tensile steels. OK Flux 10.71 is of aluminate basic type and has for this slag system very high current-carrying capacity on both AC and DC and for a very good operability characteristics both in single and multiwire systems. OK Flux 10.71 can be used to particular advantage for narrow gap welding due to the excellent slag detachability and smooth blending of the weld bead with the joint side walls.
