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.
