Ultrasonic is a sound with acoustic frequencies between 16 kHz and 1 GHz. Its vibrations can be applied to workpieces which are held together under pressure to create a solid weld.

Compare to tradition welding, ultrasonic welding is very time-saving due to no drying or curing time is need. It is also cost-effective, because you don’t need any glue, fasteners or soldering materials. Ultrasonic welding produces a high-quality bond, superior to many other methods of joining parts. No filler materials and no excessive heat means that there is no potential introduction of contaminates or thermal distortion.
