Top quality best price SAW welding wire model EM12K carbon steel copper coated submerged arc welding wire for coil nail
Top quality best price SAW welding wire model EM12K carbon steel copper coated submerged arc welding wire for coil nail
Submerged arc welding wire AWS EM12, is a kind of medium-manganese and medium-silicon type welding wire. It matches with medium-manganese and medium-silicon type welding flux. and not sensitive to the rust on the base metal. It has excellent bead molding and slag detachability. The wire can be applied single or dual feeding with AC/DC.
