AWS EL8 Submerged-arc Welding Wire

AWS EL8 Submerged-arc Welding Wire

GB H08A AWS EL8

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

Uses:Used for both high speed welding and filling welding on 50kg class base metals.
