摘要： A surface of an article is heated and subjected to pressure by operation of a friction stir tool. The pressure of the face of the tool on the article surface, and the speed of rotation of the tool and of its progression along the surface of the article, are controlled to progressively hot-work a specified surface area. The face of the tool may be round and have a profiled, axially extending, smaller diameter pin for higher concentration of frictional heat and load and for plasticizing a surface layer of the workpiece. Such hot work may be applied for reducing surface porosity or for producing another change in the surface microstructure, or for effecting another change in surface material properties.

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： A device for use with a welding apparatus, such as a friction stir spot welding (FSSW) apparatus, that maintains work pieces in a generally flat or flush orientation during a welding operation. The device can be mounted to the operable end of an FSSW apparatus so that it exerts a stabilizing force against an upper work piece. The stabilizing force exerted by the device prevents the upper work piece from deflecting when the rotating tool of the FSSW apparatus passes through the upper work piece and penetrates into the lower work piece. In an exemplary embodiment, the device includes a housing component that slidably receives a movable component under the force of a biasing component.

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： 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： A current collector plate, also called a bipolar plate, for a fuel cell includes two facing metal sheets with fluid channels for the fuel (often hydrogen) on the non-facing side of one sheet and fluid channels for air on the non-facing side of the other sheet. Such a plate is made by applying a patterned coating of particles of a soft and reactive metal to at least one of the sheets and rolling them together so that the soft metal particles deform and interact with the facing sheets to selectively join them at the patterned areas. Pressurized fluid is introduced between the sheets to expand non-bonded portions and define the fluid channels.
