In order to efficiently reduce the fonnation of corrosion irradiation activated scales, an overlay cladding will be build - upon the wetted surlace of low - alloy steels . According to the welding procedure qualification of the ASME BPVC IX., the essential variab les of shielded metal arc welding SMAW for corrosion - resistant overlay cladding welding procedure qualification are analyzed, and per the ASME BPVC fil - ~B, the SMA\: e
