  • Patent number: 11531318
    Abstract: Embodiments of welding work cells are disclosed. One embodiment includes a workpiece positioning system, a welding power source, and a welding job sequencer. The workpiece positioning system powers an elevating motion and a rotational motion of a workpiece mounted between a headstock and a tailstock to re-position the workpiece for a next weld to be performed. The welding power source generates welding output power based on a set of welding parameters of the power source. The welding job sequencer commands the workpiece positioning system to re-position the workpiece from a current position to a next position in accordance with a next step of a welding sequence of a welding schedule. The welding job sequencer also commands the welding power source to adjust a current set of welding parameters to a next set of welding parameters in accordance with the next step of the welding sequence of the welding schedule.

  • Patent number: 11504788
    Abstract: A welding or additive manufacturing system includes a power supply having a controller which controls operation of the power supply. The power supply provides a current waveform to a contact tip assembly having a first bore terminating at a first exit orifice and a second bore terminating at a second exit orifice. The first exit orifice is configured to deliver a first wire electrode and said second exit orifice is configured to deliver a second wire electrode. The exit orifices are separated from each other by a distance configured to facilitate formation of a bridge droplet between the wire electrodes while preventing solid portions of the first wire electrode delivered through the first bore from contacting solid portions of the second wire electrode delivered through the second bore, during a deposition operation in which the current waveform is conducted to both of the wire electrodes simultaneously through the contact tip assembly.

    Abstract: A welding or additive manufacturing wire drive system includes a welding wire spool and first and second drive rolls. One or both of the drive rolls has a circumferential groove. The system includes a first welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove, and a second welding wire, drawn from the welding wire spool, and located between the drive rolls in the circumferential groove. The first welding wire contacts the second welding wire between the first drive roll and the second drive roll. The first welding wire further contacts a first sidewall portion of the circumferential groove, and the second welding wire further contacts a second sidewall portion of the circumferential groove. Both of the first welding wire and the second welding wire are radially offset from a central portion of the circumferential groove.

  • Patent number: 11498146
    Abstract: A welding or additive manufacturing system includes a contact tip assembly having first and second exit orifices. A wire feeder is configured to deliver a first and second wire electrodes through the exit orifices. An arc generation power supply is configured to output a current waveform to the wire electrodes simultaneously, through the contact tip assembly. The current waveform includes a bridging current portion, and a background current portion having a lower current level than the bridging current portion. The bridging current portion has a current level sufficient to form a bridge droplet between the wire electrodes before the bridge droplet is transferred to a molten puddle during a deposition operation. Solid portions of the wire electrodes do not contact each other during the deposition operation. The bridge droplet is transferred to the molten puddle during a short circuit event between the molten puddle and the wire electrodes.
