US Patent:

20200368843, Nov 26, 2020

Filed:

Aug 12, 2020

Appl. No.:

16/991432

Inventors:

- Newport News VA, US
Daniel John Hebert - Carrollton VA, US
Kyle A. Wade - Poquoson VA, US

International Classification:

B23K 20/10
B23K 37/02

Abstract:

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.

Abstract:

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.

Abstract:

An additive manufacturing (AM) apparatus includes a build chamber, a build platform disposed within the build chamber for supporting an AM build part therein, and a build material deposition device. The apparatus further includes an energization arrangement having at least one energization source. The energization arrangement is capable of, in a fusion energy operation, selectively applying energy to a layer of build material to fuse the build material to form a next-to-be-produced layer of the AM build part and, in a material processing operation, selectively applying energy to and processing the surface of a last-produced layer of the AM build part, the layer of build material, and/or a surface of the next-to-be-produced layer.
