Abstract: In drawing wire of compound material with a core of aluminum and a casing of copper, in order to join two wire ends for continuous drawing, the copper close to the end of the wires is removed, and the adjacent portion is tapered downwardly. The two ends are then butt-pressure welded and the burr is cut off. The exposed area of aluminum at the burr and the adjacent parts of the wire are then provided by sputtering with a metallic material of good malleability and good electrical conductivity such as silver or gold.
