  • Publication number: 20160167151
    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: 20150375326
    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.

  • Publication number: 20150076119
    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: 20140367370
    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 constant voltage (CV) welding process power supply is provided. The power supply includes a controller configured to detect a short circuit event in a CV welding process and increase a welding current based upon a periodically computed voltage error and a first gain to attempt to clear the short circuit event. The controller is further configured to detect whether the short circuit event has cleared after the first current increase. If the short circuit event has not cleared, the controller increases the welding current based upon the periodically computed voltage error and a second gain higher than the first gain.

  • Publication number: 20120248080
    Abstract: Stickout of a welding electrode wire from a welding torch is determined during welding, and based upon a welding parameter, such as welding current. Different relationships are used for the determination depending upon whether the welding wire is in a short-circuit condition or an arc condition. The stickout may be converted to a standardized unit of measure to make it readily understandable to an operator. The stickout may be logged and associated with other parameters and information, such as workpiece, operator, welding system, date and time. The stickout may be used as the basis for an alarm or a disabling operation. Moreover, the stickout may be provided on a readout for the operator. It may also be used as a basis for controlling a wire feeding apparatus that retracts the welding wire to a desired stickout following a weld.
