Ultrasonic Welding is the process of joining two plastic work pieces or any other dissimilar materials by using high frequency acoustic vibrations. The work pieces are hold together under pressure. Reed Switches could be damaged by ultrasonic welding and trials are required to ensure that the harmonics of the housings and the enclosed reed switch do not interact.

Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld. It is commonly used for plastics and metals, and especially for joining dissimilar materials. In ultrasonic welding, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind the materials together. When used to join metals, the temperature stays well below the melting point of the involved materials, preventing any unwanted properties which may arise from high temperature exposure of the metal.
