  • Publication number: 20200346298
    Abstract: Systems and methods for cleaning a wire electrode after a welding process has ended are described. During a welding process, a wire electrode may be fed forward from a wire feeder through a welding torch to create a molten weld pool. While, conventionally, feeding of the wire electrode stops when the welding process ends, the present disclosure contemplates instead continuing to feed the wire electrode forward after the welding process ends. More particularly, the present disclosure contemplates feeding the wire electrode into the weld pool so that the wire electrode can be “cleaned” in the molten weld pool created by the welding process. The “cleaned” wire electrode end can be more easily used to establish an electrical arc at the beginning of the next welding process.

  • 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: 20200101555
    Abstract: Apparatus, systems, and/or methods for weld wire preheating are disclosed. Some examples of the present disclosure relate to welding-type systems that use one or more preheaters to heat welding wire prior to an arc and/or deposition on a weldment. The welding wire may have one or more characteristics. A preheating control may determine a governing characteristic of the one or more welding wire characteristics and establish a threshold temperature and/or target temperature based on the governing characteristic. The preheating control may further control the one or more preheaters based on the threshold temperature and/or target temperature, in order to avoid a deformation and/or degradation of the welding wire that would impact column strength, wire feeding, weld process stability, and/or welding consumable longevity.

  • 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.

  • 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.
