    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.

    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.

    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.

    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.
