    摘要： Laminated steel panels which are subjected to forming and assembly operations such as welding that subject the composite construction to high temperatures in localized regions. The metal laminate structure has metal skins sandwiching one or more layers of polymeric material. The polymeric material incorporates cavity structures which are designed to accommodate the gaseous components liberated during welding and other high temperature processes.

    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： An end ring assembly for a rotor, wherein the rotor is rotatable about a central longitudinal axis, includes a plurality of annular sheets stacked adjacent one another. Each of the plurality of annular sheets has a first surface and a second surface spaced opposite the first surface. The end ring assembly also includes a braze material sandwiched between and joining only a first portion of the first surface of each of the plurality of annular sheets, and a corresponding second portion of the second surface of a respective adjacent one of the plurality of annular sheets without joining an entirety of the first surface of each of the plurality of annular sheets and the second surface of the respective adjacent one of the plurality of annular sheets. A method of forming the end ring assembly is also disclosed.

    摘要： Copper conductor members or other copper-base workpieces are welded using a suitable copper alloy material that is reactive with the joining surfaces of the copper members. The reactive metal material may be applied as a thin metal strip between assembled facing joining surfaces. The members are pressed together against the reactive material and heated. The combined pressure and heat enable the reactive material to react with facing workpiece material, to liquefy and remove oxides or the like that might inhibit the formation of a welded interface. The liquid, containing original reactive metal and byproducts, is squeezed from the interface of the workpieces to enable the formation of a solid-state weld between them without melting of un-reacted workpiece copper material.

    摘要： A method of joining a first and a second work piece, such as automotive closure panels, includes supporting the work pieces on a fixture, and then joining the work pieces to one another by a first solid state weld with a vibrating roller head of a tool assembly, such as a robotically-controlled ultrasonic seam welder. Next, a flange of the second work piece is hemmed about an outer periphery of the first work piece using the same or a different roller head with the work pieces supported by the fixture. The hemmed flange is then joined to the first work piece by a second solid state weld with the vibrating roller head of the robotically-controlled ultrasonic seam welder. A system for joining a first and a second work piece is also provided.
