Abstract:
A one-sided spot welding device having a concentrically arranged weld electrode assembly and an electromagnet for clamping together and holding metallic parts during a one-sided spot welding process. A device of the present invention may include a mounting base having a central weld electrode and an outer, concentrically arranged weld electrode extending therefrom. The outer weld electrode may surround or partially surround the central electrode, with some gap therebetween. The central electrode is associated with an actuator that is provided to press a tip of the central weld electrode against a metal component to be welded. An electromagnet resides between the central and outer weld electrodes of the electrode assembly to draw metal components into tight abutting contact and to hold the components in contact with the outer weld electrode during welding.
