摘要： Local heat may be generated through surfaces of sheet metal workpieces by supporting the workpiece(s) on a hard surfaced anvil and engaging the opposite surface of the workpiece with a rotating, and optionally translating, friction stir tool that is pressed against the work surface. Advantages are realized in friction stir processing (e.g. seam or spot welding) of such sheet metal workpieces by using an anvil with appreciable thermal conductivity, or a liquid cooled anvil body, to suitably cool the site(s) of the workpiece engaged by the friction stir tool to minimize or eliminate distortion of the workpiece.
