Ultrasonic welding is a process whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. It is commonly used for plastics and metals, and used in a broad spectrum of industries. This process is often used when components become to expensive or complex to be molded as one piece.

In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. This is made possible because the vibrations creates friction between the two parts, which in turn melts the parts and forms a strong weld.
