摘要： A spot welding apparatus adapted particularly for joining aluminum workpieces utilizes a twisting or vibrating motion to break up oxides on the workpiece surface for improved welding and increased welding tip life. In one embodiment, a vibration inducing device is fixed to the electrode holder of a spot welding apparatus for vibrating the electrode tip during welding. In another embodiment, a camming mechanism rotates the electrode tip of the spot welding head in response to the spot welding head contacting the workpiece surface. The electrode tip rotates or twists in a limited arc after the tip contacts the workpiece to break up oxides on the workpiece surface. The electrode tip, upon removal from the workpiece surface, reverses its rotation for subsequent spot welding and to minimize the possibility of the electrode sticking to the workpiece.
