Ultrasonic Welding Systems Use Ultrasonic Energy To Perform Various Bonding And Cutting Functions

Ultrasonic welding systems use ultrasonic energy to perform various bonding and cutting functions such as metal joining, resin welding, resin fusion cutting, resin cutting, and even food cutting. The basic components of an ultrasonic welding system include the ultrasonic generator unit (power source) and the main unit of the welding machine (welding head/press).

Welding is achieved by utilizing the heat generated at the boundary surfaces of the objects by applying ultrasonic vibrations and forces to the objects to be joined.

Components of an ultrasonic welding system:

Ultrasonic generators: Commercial power line frequency (50/60 Hz) sources are converted to high electrical frequencies in the ultrasonic range or higher

Ultrasonic transducers and cones: converting electrical frequencies to mechanical vibration frequencies and amplitudes

Horn: Resonates with the vibration of the transducer, vibrates, applies force to the object to be connected, and directs energy to the area to be connected

Anvil (support fixture): used to position and secure the objects to be joined so that vibration energy does not escape

Ribs: It helps guide and concentrate energy in the connecting part
