ABSTRACT:
A method of producing a weld overlay on a ferrous base metal surface, by applying to the surface by electric arc welding a plurality of layers of an austenitic stainless steel filler of specific composition, and providing a flux which produces a substantially fully austenitic overlay at least in the uppermost layer. The overlay has improved machinability, metal-to-metal wear resistance and corrosion resistance, and the capability of work hardening.
