ABSTRACT:
A conductor wire is passed through a bath of molten metal in a container. While it is passing through the bath of molten metal, the wire is heated by the Joule effect by an electric current produced by a current source. This improves the adhesion of the metallic surface layer deposited on the core of the wire, so that the wire can be drawn directly by dies downstream of the bath of molten metal. This provides a fast and low-cost method of manufacturing a spark erosion electrode wire.
