Abstract
The present disclosure can provide for an ultrasonic welding method for a pair of workpieces. The method can include first pressing an ultrasonic welding stack against a first workpiece in the pair so that the first workpiece comes into contact with a second workpiece in the pair. The method can then provide for initiating a weld phase by outputting energy from the ultrasonic welding stack to the first workpiece. The method can provide for monitoring, with at least one sensor, a sensed parameter. The sensed parameter can be, for example, weld force and/or weld force rate of change. The method can provide for determining whether the sensed parameter has reached a predetermined level. Based on determining that the sensed parameter has reached the predetermined level, the method can provide for ending the weld phase.
