===== Ultrasonic Welding =====

Ultrasonic welding is an industrial technique that uses high-frequency acoustic vibrations to create a solid-state weld. It is commonly used for plastics as well as for joining two dissimilar materials together. A primary advantage of ultrasonic welding is that it does not require any connective bolts, nails, soldering material or adhesives to bind the materials together.
