Patent number: 11897046Abstract: A welding apparatus has a guide rail arrangement with at least one guide rail attachable to a welding target. A carriage has a carriage housing and a rail follower assembly that is movably mountable to the guide rail arrangement for relative movement along the at least one guide rail. A feedstock source is disposed within the carriage housing and configured to deposit a feedstock material on a target surface of the welding target. An ultrasonic weld head is partially disposed within the carriage housing and has a sonotrode that extends toward the target surface so as to engage the deposited feedstock material and apply a normal welding force to the deposited feedstock material and the target surface. The sonotrode is operable to conduct ultrasonic vibrations into the deposited feedstock material and the target surface to weld the feedstock material to the target surface.Type: GrantFiled: December 8, 2021Date of Patent: February 13, 2024Assignee: Huntington Ingalls IncorporatedInventors: John Walter Ralls, Daniel John Hebert, Kyle A.

Publication number: 20230150051Abstract: In a method of applying a weld to a target surface, a guide rail arrangement is attached to the target, the guide rail arrangement including at least one guide rail. A weld head carriage having a carriage housing, a rail follower assembly, and a sonotrode is movably mounted to the guide rail arrangement so that the follower assembly engages each guide rail for movement there-along. The weld head carriage is positioned adjacent the target surface, feedstock material is deposited onto the target surface, and the sonotrode is extended to engage the deposited feedstock material and apply a welding force to the feedstock material and the target. Relative movement between the carriage and the guide rail arrangement is initiated and ultrasonic vibrations are conducted into the feedstock material and the target, thereby welding the feedstock material to the target surface.Type: ApplicationFiled: January 17, 2023Publication date: May 18, 2023Inventors: John Walter Ralls, Daniel John Hebert, Kyle A.
