  • Patent number: 11154946
    Abstract: A welding system includes a welding torch, a power supply, one or more sensors, and a controller is provided. The welding torch advances an electrode toward a workpiece in a first direction. The power supply provides a flow of electricity to the electrode for generating a welding arc between the electrode and the workpiece. Generating the welding arc generates a weld puddle behind the welding arc as the electrode moves in the first direction. The sensor generates a voltage output signal based on the amount of light received from the weld puddle. The controller is communicatively coupled with the sensor to receive the voltage output signal, and the sensor controls a welding parameter of the welding system based the voltage output signal.

  • Patent number: 11097367
    Abstract: A method of controlling a back weld root surface includes arranging a sealing portion along the back weld root surface of a workpiece to form a purge region adjacent to a section of a joint, supplying a shielding gas within the purge region at a first flow rate, and applying a weld deposit across a front surface of the section of the joint. The shielding gas displaces an ambient environment within the purge region, and the back weld root surface of the weld deposit includes a positive root penetration relative to the back weld root surface based at least in part on the shielding gas within the purge region.

  • Patent number: 11045891
    Abstract: A method of operating a welding system includes supplying a weld current and a weld voltage to an electrode via a plurality of pulse periods, where each pulse period of the plurality of pulse periods includes a background phase and a peak phase. The method also includes detecting the occurrence of an anomalous cathode event during the background phase of a first pulse period of the plurality of pulse periods based at least in part on when a voltage value of the weld voltage is greater than a detect voltage. The method also includes controlling the weld current to a desired current during a portion of the anomalous cathode event. The portion includes an interval of the background phase of the first pulse period, and the weld current is controlled independent of the weld voltage during the portion of the anomalous cathode event.

    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.

  • Patent number: 10906114
    Abstract: A welding system includes a power supply configured to output power to a welding device. The power supply is configured to alternate the power output between an arc phase and a hotwire phase. The power output in the arc phase produces an arc between a welding electrode and a workpiece, and the power output in the hotwire phase heats the welding electrode without producing an arc.

  • 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.
