ABSTRACT:
An aluminum electrical conductor is electrically joined to a copper electrical conductor by a cold weld lap joint which is substantially free of copper-aluminum intermetallic compounds. The overlapped portions of the conductors are deformed at least 74% and no greater than 82% to achieve a weld joint which has both excellent physical properties and excellent electrical properties. The cold weld lap joint is a reliable electrical connection for electrical circuits experiencing current densities of more than 1000 amperes per square inch and a sustained high temperature of 125.degree. C. and above.
