Abstract
Electric resistance welding provides localized heating for simultaneous upset welding of the copper bars and copper end rings of an electric motor cage rotor assembly. Rapid application of an axial force completes the upset welds. The localized heating is in high current, low voltage pulses for which a homopolar welding generator is utilized.
