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 including an adhesive 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 an adhesive with copper, tin, zinc, and/or other powders can strengthen the magnesium-containing and aluminum-containing friction stir weld material.

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： 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.

摘要： A welded assembly characterized by improved structural integrity includes a first component disposed along a first plane. The first component includes first and second substantially parallel surfaces, and also includes a channel arranged on the first surface. The welded assembly also includes a second component disposed along a second plane, wherein the second component includes a leading edge. The leading edge of the second component is inserted into the channel of the first component such that an interface is formed between the first and second components. A weld generated on the second surface joins the first component with the second component at the interface such that the assembly is formed. The subject weld may be a friction-stir type of a weld. The subject welded assembly may be a vehicle bumper support. A method of forming such a welded assembly is also disclosed.
