Abstract: A converter for an ultrasonic welder includes a stack of piezoelectric disks alternately stacked with metal conductor disks in between. A pair of driver plates are disposed on opposite ends of the stack of piezoelectric disks. The piezoelectric disks include an outer perimeter surface that extends radially outward beyond the metal conductor disks. The outer perimeter surface of the piezoelectric disks can include an undulating surface.

Abstract: A work piece processing device includes a work piece processing head supported by an actuator including one of a servo actuator, a pneumatic actuator, a hydraulic actuator, an electric actuator, and a chain drive actuator. A controller uses two or more parameters concurrently in the controls of the work piece processing head and the actuator. According to a further aspect, the controller uses a time duration in the controls in conjunction with a predetermined parameter.

Abstract: An ultrasonic system has an ultrasonic stack excited by a power supply. The ultrasonic stack has a plurality of components, including an ultrasonic converter, a booster and an ultrasonic horn. A method of controlling the ultrasonic system with the power supply includes upon replacing any of the components of the ultrasonic stack with a replacement component, inputting an amplitude parameter of the replacement component into the power supply, determining with the power supply an amplitude of an AC excitation signal at which to excite the ultrasonic converter based on amplitude parameters of the components including the amplitude parameter of each replacement component. The power supply then sets the amplitude of the AC excitation signal at this determined amplitude.
