Welding Principle

Ultrasonic welding is to convert 50/60 Hz current with ultrasonic generator into 15, 20, 30 or 40 KHz high-frequency power which is then output to piezoelectric ceramic of transducer to enable the transducer to produce mechanical shock of the same frequency which is transmitted to welding head through amplitude-change pole device. The welding head transmits the received vibration energy to the joint part of workpieces to be welded. In this area, the vibration energy makes the surfaces of the two objects rub against each other to form the fusion between the molecular layers and the products are welded.
