Abstract
Methods of using metallurgical fusion to join multiple horn segments to a unitary rotary acoustic horn are described. Rotary acoustic horns comprising plurality of segments joined by metallurgical fusion are also described.
Claims20
A method of making a rotary acoustic horn comprising metallurgically fusing a first horn segment to a second horn segment;
- wherein
- the first horn segment comprises a first shaft having a first axial input end surface and a first axial output end surface, and a first horn core mechanically coupled to the first shaft;
- wherein the first horn core comprises a first circumferential welding surface integral to the first horn core, a first end surface, and a second end surface, wherein the second end surface of the first horn core comprises a first cavity defined by a first cavity wall;
- and
- the second horn segment comprises a second shaft having second axial input end surface and a second axial output end surface, and a second horn core mechanically coupled to the second shaft;
- wherein the second horn core comprises a second circumferential welding surface integral to the second horn core, a first end surface, and a second end surface;
- wherein metallurgically fusing the first horn segment to the second horn segment comprises metallurgically fusing the first axial output end surface of the first shaft to the second axial input end surface of the second shaft to form an integral shaft and metallurgically fusing at least a portion of the second end surface of the first horn core to at least a portion of the first end surface of the second horn core.
