All ultrasonic welding systems are composed of the same basic elements:
* A press to put the 2 parts to be assembled under pressure
* A nest or anvil where the parts are placed and allowing the high frequency vibration to be directed to the interfaces
* An ultrasonic stack composed of a converter or piezoelectric transducer, an optional booster and a sonotrode (US: Horn). All three elements of the stack are specifically tuned to resonate at the same exact ultrasonic frequency (Typically 20, 30, 35 or 40 kHz)
o Converter: Converts the electrical signal into a mechanical vibration
o Booster: Modifies the amplitude of the vibration. It is also used in standard systems to clamp the stack in the press.
o Sonotrode: Applies the mechanical vibration to the parts to be welded.
* An electronic ultrasonic generator (US: Power supply) delivering a high power AC signal with frequency matching the resonance frequency of the stack.
* A controller controlling the movement of the press and the delivery of the ultrasonic energy.
