Abstract
A resistance welding apparatus having a pair of programmable ball electrodes carried on universally movable positioners. The positioners are programmed to move the ball electrodes simultaneously along a seam line so that the ball electrodes clamp and support opposite sides of a pair of stacked workpieces and are electrically charged to form resistance seam welds along the seam lines to connect the workpieces.
