  • Patent number: 10828728
    Abstract: A material processing system includes a power supply and a wire feeder to feed a wire electrode for a material processing operation. The enthalpy and/or temperature of a region of the tip of the electrode is maintained substantially constant via closed loop control. The control may be based upon regulation of current applied to the electrode. The control of the current may be based upon an electrode extension error. Wire feed speed may also be controlled to assist in maintaining a substantially constant enthalpy and/or temperature near the electrode tip.

  • Publication number: 20200156172
    Abstract: A welding method includes feeding a welding electrode axially from a welding torch, moving the welding electrode radially in a desired pattern with respect to a central axis of the welding torch by a motion control assembly within the welding torch, transmitting from control circuitry a signal corresponding to a position of the welding electrode relative to a weld joint or weld pool, advancing the welding torch or a workpiece to establish a weld, and transferring material from the welding electrode to a first location in an area of the weld pool. The welding electrode moves radially while feeding the welding electrode from the welding torch, the material from the welding electrode is transferred to the first location during a first cycle of the desired pattern, and the first location is controlled based at least in part on the signal.

  • Publication number: 20200139470
    Abstract: A welding system or an enterprise using welding systems can communicate with cloud-based resources for the provision of services and products to facilitate the welding operations. The communications may be via wired or wireless media, and may be direct, or through other components, such as enterprise networks, peripheral devices, and so forth. The cloud-based resources may provide for storage of data, particularly welding data, processing of data, welding protocols, specifications and processes, financial transactions for the purchase, licensing or use of welding-related products and services, welding training, and so forth.

  • Publication number: 20190388992
    Abstract: A welding regime may implements cyclic short circuits under a closed loop voltage control approach. Upon clearing or imminent clearing of the short circuit, a current recess is implemented. The current recess reduces the current that would otherwise be applied to the weld, resulting in multiple benefits. The recess may be implemented by suspending voltage command signals. Following the current recess, normal control is resumed with the then-current voltage command.

  • Publication number: 20190366466
    Abstract: Disclosed is a welding system configured to perform additive manufacturing using a controlled short circuit welding process to apply a plurality of droplets of a wire to create a multilayer part comprised of the droplets. Operational parameters of the additive manufacturing system are dynamically adjusted based on data representing a temperature value and/or a geometric characteristic of the part. Based on the data, the controller can adjust one or more operational parameters to control application of droplets to build up the part.

  • Publication number: 20190344370
    Abstract: Disclosed is a welding-type power source that includes a first wire feeder provides a wire to a workpiece. A first wire feeder motor of the wire feeder to move the wire from a wire storage device to the workpiece. A second wire feeder motor moves the wire to and away from the workpiece and superimposes movement of the wire onto the movement from the first wire feeder motor. A moveable buffer located between the first and second wire feeder motors, and configured to accommodate a change in length of the wire between the first and second wire feeder motors when the second wire feeder motor moves the wire away from the workpiece. A sensor senses movement or displacement of the moveable buffer, wherein a speed or direction of the first or second wire feeder motors is adjusted based on data from the sensor.

  • Patent number: 10065260
    Abstract: A welding system includes an electrode configured to be advanced toward a workpiece and a power supply configured to provide a flow of electricity to the electrode for generating a welding arc between the electrode and the workpiece. The welding system also includes a first sensor configured to sense a light intensity of the welding arc and a second sensor configured to sense a current provided to the electrode via the power supply. In addition, the welding system includes a controller communicatively coupled with the first and second sensors and configured to modify the light intensity with respect to the current. The controller is configured to control a welding parameter of the welding system based on the modified light intensity.

  • Patent number: 9987701
    Abstract: Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes.
