Abstract: A metallurgically formed fluid circuit joint includes a hollow fitting (298), a tubular conduit (297), and a metallurgically formed tube/fitting mesh (296). The tube/fitting mesh (296) includes a fitting portion of the hollow fitting (298) and a tube portion of the tubular conduit (297) that is electromagnetically formed with the fitting portion.

Abstract: An electromagnetically formed fluid circuit joint (276) includes a hollow fitting (272) and a tubular conduit (274). The hollow fitting (272) has an outer surface (280) with a groove (278). The tubular conduit (274) is received over the hollow fitting (272). The tubular conduit (274) includes a fitting overlay section (284), a first wall deformation for extension of the fitting overlay section (284) over the hollow fitting (272), and an electromagnetic field formed wall deformation (291) that extends into the groove (278). Another electromagnetically formed fluid circuit joint (642) includes a hollow fitting (654) and a tubular conduit (648). The hollow fitting (654) has an inner surface (668) with a groove (666). The tubular conduit (648) is mechanically separate from and is received within the hollow fitting (654). The tubular conduit (648) includes an externally applied electromagnetic field formed wall deformation (667) that extends into the groove (666).

Abstract: An aluminum tubular unit for long-term, leak-free storage of fluids is formed in which an aluminum cap is ultrasonically welded to an end of the aluminum tube. The ultrasonic weld is formed from a device capable of producing a torsional vibration pattern. The ultrasonic welding of the cap to the tube eliminates the use of seals and pins to seal the cap to the tube and further eliminates the need for having a hole in the cap to mechanically couple the respective end cap to the cylindrical tube. Furthermore, since ultrasonic welding does not generate significant heat, highly volatile and flammable fluids can be present within the tube when the caps are ultrasonically welded to the cylindrical body. In addition, one or more fins used may also be welded to the outside diameter of the cylindrical body using a related ultrasonic welding process.

Abstract: A method for coating and an associated assembly including such a coating are provided. The assembly includes a workpiece defining a weld portion, such as a friction weld joint and a heat affected zone. A coating is disposed on the weld portion to at least partially cover the weld portion, thereby providing enhanced corrosion resistance to the workpiece.
