  • Patent number: 10145753
    Abstract: A rotor is statically or dynamically balanced by driving the rotor to rotate at a desired speed, measuring an imbalance in the rotor, calculating an adjustment to be made in a mass distribution of the rotor based on the measured imbalance, and adjusting the mass distribution to reduce the imbalance. Mass adjustment is done by operating a laser to ablate material from the rotor according to operating parameters based on the adjustment calculated. The foregoing is done while the rotor is rotating.

    Abstract: Surface asperities, such as roughness characteristics, are reduced or otherwise mitigated via the control of surface regions including the asperities in different regimes. In accordance with various embodiments, the height of both high-frequency and low-frequency surface asperities is reduced by controlling characteristics of a surface region under a first regime to flow material from the surface asperities. A second regime is implemented to reduce a height of high-frequency surface asperities in the surface region by controlling characteristics of the surface region under a second regime to flow material that is predominantly from the high-frequency surface asperities, the controlled characteristics in the second regime being different than the controlled characteristics in the first regime. Such aspects may include, for example, controlling melt pools in each regime via energy pulses, to respectively mitigate/reduce the asperities.

  • Publication number: 20130056447
    Abstract: Copper conductor members or other copper-based workpieces are welded using a suitable copper alloy material that is reactive with the joining surfaces of the copper members. The reactive metal material may be applied as a thin metal foil strip between assembled facing joining surfaces. The members are pressed together against the reactive material and electrical resistance heated in forming the weld. Practices are adapted for forming many such welds in the pairs of facing ends of conductor bars or wires assembled, for example, in slots in a stator for a vehicle traction motor. Practices are disclosed for shaping and automated placement of suitably sized and shaped foils of reactive metal. Practices are also disclosed for use of a resistance welding tool in aligning and heating the many pairs of conductors to be welded.

  • Patent number: 8362388
    Abstract: A multi-gas mixer for supplying a gas mixture that can uniformly mix a plurality of gases according to the proportional percentages determined by the mass flow rate of each gas is disclosed. The multi-gas mixer comprises a mixer chamber, a plurality of gas inlets, a gas mixture outlet, and at least one gas rotating and mixing unit. The present invention also provides a method for controlling the percentage of each gas to be mixed by use of a plurality of mass flow rate controllers to control the gas flow to produce a gas mixture according to a predetermined proportionality. When the multi-gas mixer delivers a gas mixture to a high-speed plasma torch, the torch can be stably operated under a high voltage (>85V) and a medium current (<650 A) so that a long-arc, high-temperature and high-speed plasma flame can be generated.

  • Patent number: 8334475
    Abstract: An energy beam assisted solid-state welding welds a wire material to a substrate. A wire of coating or repairing material is placed in contact with a surface or surfaces of a substrate. A beam is directed into an outer flat surface of the wire, which heats the wire through flat outer surface of the wire with beam energy. Beam energy produces compression stress-waves that drive molecules of the material flat wire into a surface of the substrate, joining the material and the substrate with strong wave shaped interfaces.
