OK FLUX 10.81LS is an agglomerated Si and Mn alloying flux for submerged arc welding. Most suitable for applications where the dilution of base metal is high, e.g. in fillet welding and butt welding of thin and medium thick plates with a limited number of passes. The superior welding properties associated with the acid slag system of OK FLUX 10.81LS permit high travel speeds in butt and fillet welding. It offers superior bead shape, slag removal and surface finish. It can be easily used over rust and primer without running into the risk of porosity.
