ABSTRACT:
A drum cathode for the production of metal foil, the drum having a titanium top cylinder and a stainless steel base cylinder integrallly connected by welding (1) a niobium or vanadium ring to the top cylinder, (2) a copper ring to the niobium or vanadium ring, and (3) the base cylinder to the copper ring, so as to provide a high electric current carrying path between the top and base cylinder. The drum cathode eliminates the formation of "hot spots" during use, while permitting increased electric current flow and foil product rate.
