  • Patent number: 11213906
    Abstract: A system for automatically brazing joints in a manifold has a loading station, a brazing station, and a cooling station. The brazing station has a plurality of brazing torches moveable to a joint in the manifold to braze the joint. First, second and third fixture frames extend from a common rotatable platform. The platform rotates each of the fixture frames to each of the loading station, brazing station, and cooling station in turn. The fixture frames support manifolds with joints requiring brazing. The torches are disposed on a lifting platform that lifts the torches up to a desired joint. The lifting platform is disposed on a sliding platform that slides the torches horizontally to the desired joint. The torches surround the joint and braze it from all sides simultaneously. While brazing is being performed at the brazing station, loading and unloading of manifolds may be done at the loading station, and cooling of already-brazed manifolds may take place at the cooling station.

  • Patent number: 9254527
    Abstract: A method is described for producing a sawing bead for use in a sawing cord. Sawing cords are used for cutting hard and brittle materials. In the method, laser cladding is used to form an abrasive layer on a small metallic tube (204) or sleeve. The abrasive layer (220) comprises a metal matrix material in which abrasive particles such as diamond, cubic boron nitride or other hard cutting materials are embedded. The metal matrix material preferably comprises an active metal that improves wetting and adhesion of the abrasive particles. Although the abrasive particles are relative large—with a particle size in excess of 100 ?m—they are evenly distributed throughout the abrasive layer. This is achieved by letting the tube (204) rotate relative to the laser cladding system possibly in combination with a relative axial movement so that the cladding track loops on itself thereby forming an abrasive layer (220). Additionally the method allows to shape the sawing bead for improved geometrical tolerances and centricity.

  • Patent number: 7875129
    Abstract: A method of assembling aluminum alloy products, such as sheets, strips or tubes, by means of fluxless brazing, where the absence of flux is made possible by using a prior treatment resulting in formation of a conversion layer on the surface of the products. The treatment involves using a solution containing K+ and F? ions and at least one acid in a quantity such that the pH of the solution is less than 3. The inventive method enables effective flux was brazing in industrial conditions, such as a for the production of heat exchangers used in motor vehicles.

  • Patent number: 7708845
    Abstract: Disclosed is a method for manufacturing thin sheets of high-strength titanium alloys. The method includes the steps of preparing initial blanks, assembling the initial blanks into a pack within a sheath, and heating and hot rolling the pack of the initial blanks in the sheath. The method is characterized in that, in the step of preparing the initial blanks, blanks having an (?-phase grain size of not more than 2 ?m are produced by hot rolling a forged or die-forged slab to a predetermined value of a relative thickness hB/hF, where hB is a thickness in mm of the initial blank before said pack hot rolling and hF is a final sheet thickness in mm, and by heat treating the initial blanks followed by rapidly cooling; and in that the step of pack hot rolling is conducted in quasi-isothermal conditions in longitudinal and transverse directions, while changing a rolling direction by about 90° after a predetermined total reduction in one direction is achieved.

  • Patent number: 7649159
    Abstract: The present invention provides technology that uniformly heats and melts a plurality of solder material arranged in a plurality of locations on a board, and uniformly solders a plurality of parts to the board that are arranged in a plurality of locations on the board. A soldering apparatus includes an induction coil having a length in the longitudinal direction that is longer than the length of the board. An inner space having a size sufficient to arrange the board therein is maintained inside the induction coil. The board supporting the parts and the solder material will be positioned in the approximate center of the inner space of the induction coil. An alternating current will flow through the induction coil in this state. An alternating magnetic field will be generated in the inner space of the induction coil. Magnetic fluxes will substantially uniformly pass through the inner space of the induction coil along the longitudinal direction of the induction coil.
