ABSTRACT A drum cathode for the production of metal foil, the drum having a titanium top cylinder and a steel base cylinder inte- grally 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 cyl- inder. The drum cathode eliminates the formation of "hot spots" during use, while permitting increased electric current flow and foil product rate.
