Product Description

AWS EM12
Submerged Arc Welding Wire
GB/T 5293 H08MnA
AWS A5.17 EM12 EN 756 S2
JIS W21

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.

Application: Matched with fused flux HJ350(AWS F7A0-EM12) or sintered flux SJ101(AWS F7A4-EM12). Used for both high speed welding and filling welding on 450-500MPa grade base metals.Like boilers, high pressure vessels.
