Publication number: 20230091609Abstract: A tubular joint includes a tubular substrate extending along an axis. The substrate has a first inner diameter. A first tubular brace member is additively manufactured on the substrate and is connected thereto at a proximal end of the first tubular brace member. A second tubular brace member is additively manufactured on the substrate and is connected thereto at a proximal end of the second tubular brace member. At respective distal ends of the brace members, the first tubular brace member and the second tubular brace member have a circular cross-sectional shape having a distal wall thickness and a second inner diameter that is smaller than the first inner diameter. At the proximal ends the of brace members, the first tubular brace member and the second tubular brace member have respective proximal wall thicknesses that are greater than the distal wall thickness.Type: ApplicationFiled: April 29, 2022Publication date: March 23, 2023Inventors: Bryan M. O'Neil, David M. Douglass, Michael S. Flagg, Bradley K. Barnhart

Patent number: 9511440Abstract: The invention described herein generally pertains to a welding device that deposits a material onto a workpiece, the welding device having with an electrode head and a contact assembly coupled thereto. The contact assembly can house electrodes that allow deposition of material on a workpiece. At least a first set of electrodes and a second set of electrodes can be driven at different speeds. Moreover, welding arcs for one or more electrodes can be established based upon a predetermined order in which the predetermined order can be based on at least one of a location of the electrode head on the workpiece, a start of a welding process, and/or a stopping of a welding process.Type: GrantFiled: August 7, 2013Date of Patent: December 6, 2016Assignee: LINCOLN GLOBAL, INC.Inventors: Steven R. Peters, Michael S. Flagg, George C. Willard

Publication number: 20160082539Abstract: The invention described herein generally pertains to a system and method related to reducing magnetic arc blow and steering the arc with two or more ground connections on the workpiece. The invention employs an AC switch component that is configured to activate one of the two or more ground connections to complete an electrical connection via the arc between the electrode and the workpiece. The activated ground connection can be used to counteract a buildup of magnetic field due to arc blow. Moreover, AC switch component can be configured to manipulate a direction of an arc based on activated a ground connection. In addition, AC switch component can oscillate between two or more ground connections to agitate a puddle formed by an electrode to release gas from the puddle and reduce porosity of a resulting weld.Type: ApplicationFiled: September 19, 2014Publication date: March 24, 2016Inventor: MICHAEL S. FLAGG
