Publication number: 20230017476Abstract: A welding or additive manufacturing wire drive system includes a spindle. First and second welding wire spools are mounted on the spindle. The spools include a flange, a mounting hub, a barrel, and a wire electrode wound on the barrel. At least two drive rolls simultaneously draw first and second wire electrodes from the spools. A clutch disk is mounted on the spindle and has respective frictional surfaces in contact with one or both of the flange and mounting hub on the spools to frictionally engage the spools. The clutch disk allows the spools to slip relative to each other during an operation of the at least two drive rolls such that the spools rotate at different speeds while the wire electrodes are drawn from the spools.Type: ApplicationFiled: June 23, 2022Publication date: January 19, 2023Inventors: Adam E.

Publication number: 20220371117Abstract: An arc welding system providing improved molten metal droplet transfer. The system includes a welding power source having a welding power supply, a welding waveform generator, and a controller. Two fluxed cored welding wire electrodes are connected to the power source and are powered by the same welding output voltage and current produced by the power source. A feedback circuit is connected to the power source to provide an adaptive response to maintain an average welding output voltage. The controller controls the waveform generator and the power supply to superimpose welding current pulses onto a welding waveform of a CV flux cored arc welding process, that uses CO2 as a shielding gas, to generate a modified waveform of a modified CV flux cored arc welding process. The current pulses are superimposed in time to form molten metal droplets between ends of the two electrodes during the modified welding process.Type: ApplicationFiled: October 20, 2021Publication date: November 24, 2022Inventors: Steven R. Peters, Matthew A. Weeks, Gregory M. McCall

Patent number: 11504788Abstract: 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.Type: GrantFiled: January 27, 2020Date of Patent: November 22, 2022Assignee: Lincoln Global, Inc.Inventors: Matthew A. Albright, Matthew A. Weeks, Steven R. Peters, Andrew R. Peters, Bruce J. Chantry
