AWS EM12 Submerged-arc Welding Wire

AWS EM12 Submerged-arc Welding Wire

GB H08MnA AWS EM12

Introduction:It is a kind of medium-manganese and medium-silicon type welding wire. It matches with medium-manganese and medium-silicon type welding flux. It is not sensitive to the rust on the base metal. It has excellent bead molding and slag detachability. Monopole or dipole. AC/DC.

Uses:Used together with fused flux 350 or sintered flux 101. Used for both high speed welding and filling welding on 50kg class base metals.
