Abstract

Aiming at the electrode tips wear problem during resistance spot welding of aluminum alloy, the authors analyze electrode tip wear processes during resistance spot welding of aluminum alloy, and then propose the resistance spot welding with cover plates to be used to weld aluminum alloy. Since the electrode tip do not contact with aluminum alloy sheet, the electrode tip service life can be lengthened.
