Abstract

An ultrasonic processing method is disclosed wherein during the processing time interval the motional amplitude and engaging force of the resonating horn (20) and thereby the power and engaging pressure to the workpiece (24) is varied to improve weld strength and decrease weld cycle time. The variation in motional amplitude and engaging force may be in response to a process condition such as a change in dimensions of the workpiece, a sharp rise in the transducer power curve, or in response to the lapse of a predetermined time interval.
