    Abstract: An additive manufacturing machine for repairing a component includes a build platform that supports the component and a powder dispensing assembly for selectively depositing additive powder over the build platform. A powder seal assembly includes a powder support plate positioned above the build platform and defining an aperture for receiving the component without contacting the component. A clamping mechanism is movable relative to the powder support plate and defines a void for receiving a resilient sealing element around the aperture. An actuating mechanism, such as bolts or a linear actuator, moves the clamping mechanism toward the powder support plate to deform the resilient sealing element until the resilient sealing element contacts and forms a seal with the component.

  • Publication number: 20200238390
    Abstract: A coating for carbide substrates employs a nanostructured coating in conjunction with a non-nanostructured coating. The nanostructured coating is produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and may be produced as multiple individual titanium and titanium-based nanostructured layers varying functional materials in a series. The combination of a nanostructured coating and non-nanostructured coating is believed to produce a cutting tool insert that exhibits longer life. Pre-treating the substrate with a mixture of compressed air and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and abrasive medium after the coating process is believed to further enhance the wear resistance and usage life of the cutting tool.

The device includes a argon arc welding machine, a GTAW torch, a welding trolley, a wire feeding device, and a gas protection device. The GTAW torch includes a rotating motor, a rotating tungsten, a conductive system, and a gas supply system. The non-axisymmetric rotating tungsten is drived by the rotating motor through the central rotating shaft. The conductive system is used for connecting and supplying electric power from the argon arc welding machine, and the air supply system is used for providing shielding gas into the welding torch. The GTAW torch is fixed on the welding trolley, and the GTAW torch is moved by the welding trolley, and the wire feeding device moves synchronously with the welding torch.

    Abstract: Systems and methods are disclosed of a welding-type system that includes a welding-type power source configured to generate output power for an arc welding process. A bi-directional wire feeder advances or retracts an electrode wire to or from a workpiece. One or more sensors measure one or more welding process parameters. And a switch is provided to open an alternative current path for arc current between an electrode wire and a workpiece. For example, the switch is to close to redirect all or part of the arc current through the alternative current path in response to one or more welding process parameters exceeding a first threshold value corresponding to a short clearance event.

  • Publication number: 20200238419
    Abstract: Systems and methods for welding are described. The welding system can include, for example, a welding power source, a welding torch, and a computer. The computer and the welding torch can be operatively coupled to the power source. A first weld is performed and its signature is saved by the computer. It is considered a high quality weld and is selected as a weld reference. A second weld is performed and its signature is saved by the computer. The computer then computes a single weld confidence result for the second weld based on a comparison between the signature data of the second weld and the signature data of the reference weld. A weld fault condition is triggered based on the single weld confidence result which causes the welding system to stop or to modify the welding operation, and/or which causes the welding system to send out communications relating to the triggering of the weld fault condition.

    Abstract: A welding control system includes a tip sensor to collect welding data from a welding tip. A controller receives the welding data from the tip sensor. The controller compares the welding data to welding parameter thresholds to determine a correction signal based on the welding data. A light generator generates light signal feedback to a welding operator in response to the correction signal.

  • Publication number: 20200238421
    Abstract: Disclosed welding-type systems and methods are directed to employing a wire feeder for feeding an electrode wire from a wire source in a welding system. The wire feeder includes one or more drive rolls to advance the electrode wire by contact force. In disclosed examples, a contact force on the wire from the drive rolls is adjustable. In some examples, the system includes a controller to receive a feedback signal corresponding to the contact force. The controller commands an actuator or other mechanism to adjust the contact force on the wire, such as by adjusting a position of the one or more drive rolls in response to the contact force falling outside a range of threshold contact force values.
