Abstract
An electrical conductor connection between at least two aluminum conductors which includes a weld nugget having a substantially cylindrical cross-sectional configuration perpendicular to the major surfaces of the aluminum conductors. The ends of the weld nugget are convexly cupped and extend outwardly past the major surfaces of the aluminum conductors to provide visual verification of joint integrity. The electrical conductor connection is formed by a method which includes providing an aperture in one of the conductors to be joined and providing a recessed backup against the other conductor, aligned with the aperture. Timed, multiple sequence MIG arc spot welding provides a weld nugget having the desired shape and diameter at the interface or throat between the two conductors. The method also enables the welding operation to be performed out of position, without sag or run of the molten pool of aluminum.
