ABSTRACT:
Two metal plates 1a, 1b are projection welded together using a truncated conical projection 12 on a first one of the plates having a spherical end surface. The plates are pressed together through the projection, and a welding current pulse is applied which reaches a maximum value in less than 2 milli-seconds. The shape and dimensional limitations of the projection coupled with the high amplitude, short duration current spike result in a thin welding nugget 9 and prevent any thermal distortion of the outer plate surface due to localized overheating.
