ES FLUX 181 is an acid 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 small number of passes.
The excellent welding properties associated with the acid slag system of ES FLUX 181 permit high travel speeds in butt welding, i.e. the spiral welding of thin-walled pipes and fillet welding, where good bead shape, excellent slag removal and top-class surface finish are essential.
