  • Patent number: 6491207
    Abstract: A directionally solidified nickel-base superalloy article has a defect therein extending parallel to the solidification direction. The article is repaired by removing any foreign matter present in the defect, and then heating the article to a repair temperature of from about 60 to about 98 percent of the solidus temperature of the base material in a chamber containing a protective gas that inhibits oxidation of the base material. The defect is filled with a filler metal while maintaining the article at the repair temperature. The filling is accomplished by providing a source of the filler metal of substantially the same composition as the base material of the directionally solidified article, and melting the filler metal into the defect progressively while moving the source of the filler metal relative to the article in a direction parallel to the solidification direction.

  • Patent number: 6409071
    Abstract: Method for welding two end portions (6, 8) of a coil (not shown) onto two electric contact pads or bumps (24, 26) of an integrated circuit (2) or an electronic unit of small dimensions. This welding method is characterised in that, prior to the actual welding step, a preliminary step is provided consisting in removing at least partially the insulating sheath from the electric wire (10) at least at the locations of the two end portions (6, 8) provided for the welding onto said electric contact pads or bumps (24, 26). The insulating sheath is removed locally by means of heat application, in particular using a heating press (58) working at a sufficiently high temperature to melt or sublimate the insulating sheath. The welding step is achieved at a much lower temperature than the temperature of the preliminary step, which allows the heat and mechanical stress to be reduced for the integrated circuit (2) and the bumps (24, 26) during welding of the ends (6, 8) onto said bumps.

  • Patent number: 6364971
    Abstract: A method of repairing a metallic member, such as a superalloy turbine blade, includes the step of preparing the blade by stripping the protective coatings from the blade. The blade is then pre-conditioned for welding by a first hot isostatic process. Once the blade conditioning sequence is complete, the blade is welded using a laser welding technique and by adding weld fillers to the weld area. After the welding step, the blade is sealed by a second hot isostatic process treatment performed at conditions similar to the first hot isostatic process. The blade is finally prepared for re-entry into service.

  • Patent number: 5660742
    Abstract: A method, machine and termination for connecting two or more insulated wire ends includes placing them in a metal tube held between fusing electrodes. The electrodes are shaped to deform the tube and wires therein with the application of fusing pressure. During fusing, pressure builds first to press the assembly together, then heat and current are applied as the tube and internal wires are compressed. Fusing current first flows from a longitudinal region of the tube equally in both direction through the tube metal to soften the tube and distribute the fusing heat broadly. As the wire insulation is burned off or flows away, current also passes through the bare wire ends to aid the fusing process. For tinned copper tubes, some of the inside tin layer flows to wet copper surfaces and dissolve copper impurities. Some tin flows to seal small spaces between the fused wires. Some of the tin on the outside surface and inside surface of the tube may vaporize.
