Abstract
An ultrasonic additive manufacturing system may include a base structure, a sonotrode configured to rotate about an axis of rotation, and one or more transducers configured to vibrate the sonotrode. The sonotrode may include a welding surface extending along a circumference of the sonotrode, and the welding surface may have a contoured profile. At least one of the sonotrode and the base structure may be configured to translate relative to the other of the sonotrode and the base structure.
Claims12
An ultrasonic additive manufacturing system comprising:
- a base structure;
- a sonotrode configured to rotate about an axis of rotation, wherein the sonotrode comprises a welding surface extending along a circumference of the sonotrode, wherein the welding surface has a V-shaped profile and a first side and a second side disposed opposite one another in a direction of the axis of rotation, wherein the welding surface has a central plane disposed between the first side and the second side in the direction of the axis of rotation, wherein the central plane extends perpendicular to the axis of rotation of the sonotrode and is centered with respect to the welding surface in the direction of the axis of rotation, wherein the welding surface has a maximum diameter located in the central plane, and wherein at least one of the sonotrode and the base structure is configured to translate relative to the other of the sonotrode and the base structure;
- and
- one or more transducers configured to vibrate the sonotrode.
