摘要： 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.

摘要： 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.

摘要： A welding operation is performed by moving or rotating an arc in a welding torch, and feeding a metal cored wire through the torch in a direct current, electrode negative welding process. The electrode may include one or more arc stabilizers. The welding process may be pulsed or non-pulsed. Moreover, the process may be used with a number of different base metals intended to be welded, such as thin plate, galvanized metals, painted metals, coated metals, and so forth. The welding system comprises a power supply (16) configured to provide power to establish an arc between a metal cored welding electrode (44) and a workpiece (14) in a direct current, electrode negative welding polarity, the metal cored welding electrode comprising a sheath and a core, a wire feeder (22) coupled to the power supply (16) and configured to feed the electrode (44) from a welding torch (24) and a welding torch (24) that, in operation, receives the electrode(44) from the wire feeder (22) while cyclically moving the electrode (44) in a desired pattern by a motion control assembly within the welding torch (24) to maintain an arc between the sheath (44) and the workpiece (14).
