Abstract

An ultrasonic apparatus useable for welding metal by vibrations in the ultrasonic frequency range, employs a horn dimensioned to be resonant as a full wavelength resonator for vibrations of a predetermined frequency traveling longitudinally therethrough. To increase the energy available, the horn is coupled to a pair of transducers, one transducer coupled to each of the radially disposed end surfaces of the horn.
During operation, one transducer must be in its longitudinal expansion mode when the other transducer is in its longitudinal contraction mode and vice versa. In order to accomplish this, two substantially identical transducers are used, but the orientation of the piezoelectric disc or discs in one of the transducers is reversed with respect to the orientation of the disc or discs in the other transducer.
