Patent number: 11198189Abstract: A welding system includes a power source configured to generate power and deliver the power to a welding torch. The power is provided in accordance with an electrode negative pulse welding regime that includes a cyclic peak, followed by a stabilization phase, then a return to a background level. The stabilization phase has a generally parabolic current shape, and is performed in a current-closed loop manner until a transition point. Resulting weld performance is improved, with a globular-like transfer mode, reduced shorts and enhanced arc stability.Type: GrantFiled: September 17, 2014Date of Patent: December 14, 2021Assignee: Illinois Tool Works Inc.Inventors: Bryan Dustin Marschke, Amanda Jean D'Arcy, Nathan Gerald Leiteritz

Patent number: 11045891Abstract: A method of operating a welding system includes supplying a weld current and a weld voltage to an electrode via a plurality of pulse periods, where each pulse period of the plurality of pulse periods includes a background phase and a peak phase. The method also includes detecting the occurrence of an anomalous cathode event during the background phase of a first pulse period of the plurality of pulse periods based at least in part on when a voltage value of the weld voltage is greater than a detect voltage. The method also includes controlling the weld current to a desired current during a portion of the anomalous cathode event. The portion includes an interval of the background phase of the first pulse period, and the weld current is controlled independent of the weld voltage during the portion of the anomalous cathode event.Type: GrantFiled: May 30, 2014Date of Patent: June 29, 2021Assignee: ILLINOIS TOOL WORKS INC.Inventors: Richard Martin Hutchison, Caleb Haven, Bryan Dustin Marschke, Peter Donald Mehn

Patent number: 10953484Abstract: A system includes a welding torch assembly configured to establish a welding arc between an electrode and workpieces separated by a narrow groove utilizing power from a power supply while moving the electrode radially in a desired pattern by a motion control assembly within the welding torch assembly. The welding torch assembly includes a nozzle through which the electrode is fed and within which the electrode is radially moved.Type: GrantFiled: September 9, 2014Date of Patent: March 23, 2021Assignee: ILLINOIS TOOL WORKS INC.Inventors: Kevin Pagano, Bryan Dustin Marschke, Thomas Roger Jaeger, Nauman Basit, Kenneth S.

The power is provided in accordance with an electrode negative pulse welding regime that includes a cyclic peak, followed by a stabilization phase, then a return to a background level. The stabilization phase has a generally parabolic current shape, and is performed in a current-closed loop manner until a transition point, where control becomes voltage-closed loop until the background level is reached. Resulting weld performance is improved, with a globular-like transfer mode, reduced shorts and enhanced arc stability.Type: GrantFiled: September 17, 2014Date of Patent: November 17, 2020Assignee: Illinois Tool Works Inc.Inventors: Bryan Dustin Marschke, Amanda Jean D'Arcy

Patent number: 10442027Abstract: A welding system includes components equipped with digital communications circuitry for synchronization and coordination of tasks associated with the welding operation. The tasks may be initiated and terminated independently or in coordination based upon synchronization of this circuitry. Certain of the tasks may be performed by the components in an open-loop manner or in a closed-loop manner based upon feedback of welding parameters. Moreover, certain tasks may be independent of one another, or interdependent although carried out in parallel by the different system component.Type: GrantFiled: November 14, 2016Date of Patent: October 15, 2019Assignee: ILLINOIS TOOL WORKS INC.Inventors: Bryan Dustin Marschke, James Donald Borowski, Peter D.

Patent number: 9987701Abstract: 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.Type: GrantFiled: July 15, 2016Date of Patent: June 5, 2018Assignee: Illinois Tool Works Inc.Inventors: Richard Martin Hutchison, James Lee Uecker, Todd Earl Holverson, Bryan Dustin Marschke, Robert Raimund Davidson, Richard J.

Patent number: 9403233Abstract: 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.Type: GrantFiled: November 20, 2012Date of Patent: August 2, 2016Assignee: ILLINOIS TOOL WORKS INC.Inventors: Kevin Pagano, James Lee Uecker, Steven Barhorst, Bryan Dustin Marschke, Mario Amata
