220V Ultrasonic Metal Welding

Ultrasonic Metal Welding for Automotive Electronic Control Circuit of Safty Airbag

Description: 

The principle of ultrasonic welding is to convert 50/60 Hz power frequency to 20 kHz or more by ultrasonic generator. The converted high frequency electrical energy is again converted by the transducer into mechanical vibration of the same frequency, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude. The welding head transfers the vibration energy to the joint of the workpiece to be welded, in which the vibration energy is converted into mechanical energy and thermal energy by friction, so that the workpiece to be processed is welded. Ultrasonic waves can be used not only to weld hard thermoplastics, but also to weld metals.

Ultrasonic welding of plastics generally uses the direction of vibration of the welding head and the vertical of the workpiece. For some thin plastic parts, the direction of vibration of the welding head and the parallel of the workpiece can also be used. When ultrasonic welding of metal, the direction of vibration of the welding head is parallel to the workpiece.

The main components of a set of ultrasonic welding systems include ultrasonic generators, transducers, amplitude modulators, welding head triples, molds and frames. The main function of the frame is to fix and form a pressurizing mechanism.
