  • SINGLE DRIVE AND SOURCE FOR ADJACENTLY CLAMPING AND RESISTANCE WELDING
    Publication number: 20070175868
    Abstract: A resistance spot welding system (10) for sequentially clamping a plurality of workpieces (20,22) at predetermined locations and welding the workpieces (20,22) substantially adjacent the locations, including a clamping element (24) able to be locked in a workpiece engaged position, at least one set of equalizing welding electrodes (28,30) for oppositely engaging the workpieces (20,22) so as to produce the weld (12) without deformation, a singular drive mechanism (14) including a cam coupled to the clamping element (24) and electrodes (28,30), and a singular source (16) for actuating the mechanism (14) and generating the welding and clamping forces.
