In addition, ultrasonic welding is relatively easy to automate and is particularly suitable for high volume production. Rapid development of the ultrasonic welding machine has occurred in the last ten years. Basic functions, such as weld energy, collapse, trigger force, and pressure are now microprocessor-controlled. In addition, real time feedback and control of welding conditions is being offered, along with the ability to vary weld force and amplitude during the weld cycles. The benefits of a amplitude control were reported recently.
