    Abstract: A component is produced in layers by laser melting. A molten pool is created in a bed of powder by a working laser beam. Further auxiliary laser beams are set to a power density that merely slows down the cooling of the material in one zone, but do not cause any renewed melting. In this way, the cooling rate of the microstructure can be set so that an advantageous structural formation develops. This allows for example the mechanical properties of the component produced to be advantageously improved without downstream heat treatments.

    Abstract: A process for closing an opening in a surface of a component, and components formed thereby. The process entails forming a channel in the component surface so that the channel at least partially surrounds an opening at the component surface. An alloy is then deposited in the channel to form a crack-free deposit in the channel. A step is then machined that intersects the opening and is at least partially formed in the deposit. The step defines a recess that is at least partially surrounded by a peripheral portion of the deposit and has a surface recessed into the component surface. A cap is placed in the recess and welded to the peripheral portion of the deposit to define a weld joint that completely closes the opening. The surface of the weld joint is then machined to form a machined surface that is substantially flush with the component surface.

  • Patent number: 8816239
    Abstract: A method of manufacturing a component. The method includes the steps of heating a working region of a substrate with a heating means; directing a material into the working region to bring the material into a temporary molten state, and depositing said material on the substrate such that when the material solidifies it forms at least part of the component. The heating means power output, stand off, orientation, speed and direction of travel relative to the substrate are adjustable and controlled throughout the material deposition process to control the shape and/or size of the working region to thereby control the distribution and rate of heat delivery to the substrate.

  • Publication number: 20140131338
    Abstract: Various embodiments of a metal cored wires, hardband alloys, and methods are disclosed. In one embodiment of the present invention, a hardbanding wire comprises from about from about 16% to about 30% by weight chromium; from about 4% to about 10% by weight nickel; from about 0.05% to about 0.8% by weight nitrogen; from about 1% to about 4% by weight manganese; from about 1% to about 4% by weight carbon from about 0.5% to about 5% by weight molybdenum; from about 0.25% to about 2% by weight silicon; and the remainder is iron including trace elements. The hardband alloy produced by the metal cored wire meets API magnetic permeability specifications and has improved metal to metal, adhesive wear resistance compared to conventional hardband alloys.

  • Publication number: 20140124483
    Abstract: Layered metal deposition by fusion thereof onto a surface of an engineered structural member, without degrading structural performance. The net shape of an exterior member is defined, including a fusion contact area. The structural member is preheated below its maximum operating temperature. An energy beam and feedstock are directed to a feed point in the fusion area, thereby forming a molten puddle fusing the materials together. The feed point is moved relative to the structural member, thereby advancing the molten puddle of presently fed feedstock and rapidly solidifying previously fed feedstock. The energy beam power is modulated to control the size of the molten puddle so as not to exceed a predetermined depth of penetration of the fusion region into the structural member. Advancing the feed point sequentially fuses feedstock into the defined net shape on the structural member.

  • Patent number: 8715772
    Abstract: A process for the thermal deposition coating of a workpiece is provided that comprises the steps of: thermally depositing a coating on a metallic surface of a workpiece from a deposition head wherein at least one condition selected from the group of: coating deposition rate onto said surface, relative motion between the surface and said deposition head, and cryogenic coolant application rate onto said workpiece is controllable; substantially simultaneously measuring temperatures at a plurality of locations over the metallic surface of the workpiece; determining an average temperature of the temperatures measured in step (b); comparing the average temperature to a preselected minimum temperature and a preselected maximum temperature for the workpiece; and adjusting at least one of the controllable conditions if said average temperature is not between the preselected minimum temperature and the preselected maximum temperature for the workpiece.
