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.

摘要： When a friction stir weld tool penetrates the interface of two workpieces of dissimilar metal alloy materials, the resultant weld of the different alloy materials may produce a weak weld joint. Such weak joints are often experienced, for example, when attempting to form spot welds or other friction stir welds between a magnesium alloy sheet or strip and an aluminum alloy sheet or strip. It is discovered that suitable coating compositions placed at the interface of assembled workpieces can alter the composition of the friction stir weld material and strengthen the resulting bond. In the example of friction stir welds between magnesium alloy and aluminum alloy workpieces, it is found that combinations of copper, tin, and zinc, and other powders can strengthen the magnesium-containing and aluminum-containing friction stir weld material.

摘要： An apparatus and method is provided for hemming together a pair of panels and immediately sealing the hemmed joint against the intrusion of moisture. A tool mount is attached to a multi-axis manipulator such as a robot for moving the tool mount along the edge portions of the panels. A hemming roller is mounted on the tool mount and adapted to be moved along the edge portions of the panels by the multi axis manipulator to fold the flanged edge portion of the outer panel onto the edge portion of inner panel as the tool mount traverses the edge portions of the panels. A sealing mechanism is mounted on the tool mount adjacent to the hemming roller to seal the hemmed joint immediately after the flanged edge portion is folded onto the inner panel. The sealing mechanism may be a dispenser of adhesive sealer or a friction stir welder.

摘要： Aluminum alloy workpieces and/or magnesium alloy workpieces are joined in a solid state weld by use of a reactive material placed, in a suitable form, at the joining surfaces. Joining surfaces of the workpieces are pressed against the interposed reactive material and heated. The reactive material alloys or reacts with the workpiece surfaces consuming some of the surface material in forming a reaction product comprising a low melting liquid that removes oxide films and other surface impediments to a welded bond across the interface. Further pressure is applied to expel the reaction product and to join the workpiece surfaces in a solid state weld bond.

摘要： In an assembly of facing metal sheets separated by a polymer layer, welded metallurgical bonds are formed between the metal sheets by use of a friction stir weld tool. A rotating tool penetrates the first sheet, locally displaces the encountered portion of polymer film and penetrates into the second sheet. The affected metal of the two sheets is momentarily plasticized and stirred, and the plasticized metal of the two sheets combines to form a weld between the metal sheets. The interposed polymer film may be intended to serve as an adhesive or a vibration damping medium or the like. The facing metal sheets can be layers of facing laminated metal sheet structures that each comprise two metal sheets bonded by an adhesive interlayer.

摘要： One side of a metal sheet is joined to a polymer layer by applying heat to a joining area on the opposite side of the metal. The heat flows through the thin metal to activate a thermoplastic material or heat setting polymer into a bond with the metal. The method can be used to bond the metal sheet to a plastic body or another metal member. It is preferred to use a friction or friction stir tool to heat the metal surface.

摘要： The present invention provides an apparatus and improved method of friction stir spot welding that assures a predetermined bottom thickness and a reduction in variation in a series of resultant spot welds. The advantage of the present invention lies in that the plunge distance is controlled from the top plane of the anvil against which the bottom thickness is specified, and systematically adjusted to account for changing system parameters, such as, but not limited to, deflection and thermal expansion of the weld gun. The present invention also provides for improved and controlled weld quality through implementation of a dwell operation or dwell operations, whereby weld heat input is manipulated by causing the weld tool to dwell in a dwell region or at a desired depth or depths within the workpiece(s) for a predetermined time interval to achieve desired mechanical properties of the resultant weld joint.
