Abstract
An ultrasonic welding system and a method are provided. The system includes an ultrasonic welding device having an ultrasonic welding horn. The system further includes a controller generating control signals for inducing the welding device to form a first weld joint. The system further includes a power adjusting unit that induces the ultrasonic welding controller to increase a power level output by the ultrasonic welding controller to the ultrasonic welding device if a first displacement of the welding horn is less than the desired displacement during partial completion of forming the first weld joint, such that upon completion of the first weld joint an ending position of the ultrasonic welding horn is at a desired ending position.
