ABSTRACT:
An aluminum insert, friction welded to a copper plate, is projected through a close-fitting aperture in an aluminum busbar and joined to the busbar by a circumferential weld at the exit end of the aperture, using conventional arc welding techniques, to complete a high ampacity, aluminum-copper electrical joint. The copper plate is then bolted to a copper strap in conventional high ampacity, bolted electrical joint fashion.
