Abstract
A rotary acoustic horn imparts energy at a selected wavelength, frequency, and amplitude. The horn includes a shaft having an axial input end and an axial output end and a welding portion. The welding portion is mounted on the shaft and has a diameter that is greater than the diameter of the shaft. The welding portion has a weld face that expands and contracts with the application of acoustic energy. At least a portion of the weld face can be formed of a different material than the remainder of the welding portion. The welding portion can include a sleeve. The sleeve can be shrink fit onto the welding portion.
