  • Publication number: 20090114623
    Abstract: One method of the invention is for welding and includes obtaining first and second members each including an extrusion having a through hole and includes obtaining first and second electrodes each having an electrode portion. The second member is positioned to have the second extrusion nest in the first through hole against the first extrusion. The first electrode is positioned to have the first-electrode portion nest in the second through hole against the inside of the second extrusion. The second electrode is positioned to have the second-electrode portion contact the outside of the first extrusion. Another method of the invention is for welding and includes obtaining a tube having an end form and a member having first and second portions. The tube and the member are positioned with the end form contacting the first portion while leaving a recess between the end form and the second portion.

  • Patent number: 6717091
    Abstract: A method for metallurgically attaching together two tubes. A first tube is obtained having a far wall portion with a first through hole and a near wall portion with a second through hole. A second tube is obtained including first and second outward folds. The tubes are positioned with the first fold passed through the second through hole and contacting the far wall portion surrounding the first through hole and with the second fold located outside the near wall portion. A first resistance welding current path is created proximate the first fold and the far wall portion and the first fold is relatively moved deformingly against the far wall portion creating a first weld zone. A second resistance welding current path is created proximate the second fold and the near wall portion and the second fold is relatively moved deformingly against the near wall portion creating a second weld zone.

  • Publication number: 20040035829
    Abstract: A method for manufacturing a tubular assembly. A first tube is obtained. A first tubular connector is obtained having a first and second end portions. The first end portion is metallurgically attached to the first tube. A tubular member is obtained having a third end portion. At least one of the second and third end portions includes an annular outward fold including spaced-apart first and second fold portions. The first tubular connector and the tubular member are positioned with the second end portion aligned with and contacting the third end portion. A resistance welding current path is created through the first tubular connector and the tubular member proximate the second and third end portions and the second and third end portions are relatively and deformingly moved together creating a weld zone which includes at least some of the second and third end portions.

  • Patent number: 5195571
    Abstract: Molten metal is die cast directly to and around a surface of a fiber reinforced plastic part in such a way as to actually take advantage of the thermal decomposition of the part resin caused by the hot metal. The molten metal is introduced to the surface and cooled just rapidly enough to allow a controlled, limited resin decomposition to occur at the top surface. Molten metal then flows in and around the exposed fibers, creating a secure interlock.
