    摘要： In a Friction Stir Welding process a load, applied through a rotating tool, frictionally heats, plasticizes and commingles selected regions of the workpieces while translating along the length of the joint. The load is supported by an anvil. The applied load inhibits relative motion of the workpiece and conventional anvils due to friction which requires application of higher translation forces and could lead to undesired surface blemishes. Thus conventional practice is to employ bulky, stationary anvils. Compact, moveable anvils comprising freely-rotating or freely moving elements in contact with the workpieces and capable of reducing workpiece-anvil friction are described. Particular benefits of this anvil design are illustrated for the process of assembling inner and outer sheet metal components into an automobile assembly, a portion of which is visible to a vehicle customer.

    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.

    摘要： A welding apparatus for an induction motor includes a fixture operable to support a rotor and rotate the rotor about an axis of rotation of the motor, and a welding head supported adjacent the fixture and operable to weld conductor bars located about the surface of the rotor to the first shorting ring when the fixture supports the rotor. A controller controls the fixture to selectively rotate the rotor. The controller moves the welding head, the fixture, or both, so that the welding head is in a welding position, and causes the welding head to weld the conductor bars to the first shorting ring while remaining in the welding position, with the rotor rotating to create a substantially circular weld path along the first shorting ring. In some embodiments, the conductor bars are welded to both shorting rings simultaneously. A method of welding an induction motor is also provided.

    摘要： A method of performing a plurality of friction stir spot welds with a friction stir spot welding (FSSW) system includes measuring a length of a pin of a weld tool of the FSSW system. The length is compared to a first limit to determine if the length is above or below the first limit. Debris is removed off of a tip of the pin when the length is determined to be above the first limit. The length is also compared to a second limit to determine if the length is above or below the second limit. At least one friction stir spot weld is performed on a workpiece when the length is determined to be less than the first limit and above the second limit.
