Welding principle:
Ultrasound is a mechanical vibration, similar to the vibration produced by musical instruments. These vibrations are called ultrasonic waves because their frequency is higher than human hearing (greater than 16 kHz). In the acoustic component, these pressure waves are generated by a generator. This will send alternating current at the same frequency as the converter (or transducer). Then, a transducer made of piezoelectric ceramics converts this energy into mechanical vibration. Then, mechanical vibration will generate thermal friction, which will stimulate the molecules of the material being welded to start moving. Ultrasonic energy will melt the contact points between the two parts, thereby forming a joint, allowing the parts to bond quickly.
