Handheld Ultrasonic Spot Welder

Compared with traditional processes (such as gluing, ironing or screw fastening), ultrasonic spot welding has significant advantages such as high production efficiency, good welding quality, environmental protection and energy saving. The handheld ultrasonic welding machine can also be used for welding and riveting of thermoplastic products, as well as inlaying and blanking processes between metal and plastic parts. The process of replacing the organic melting point paste has been completed, and has the characteristics of low energy consumption, high efficiency, no deformation, no pollution, solid welding, and convenient operation.


Ultrasonic waves can be used not only for welding metals, rigid thermoplastics, but also for fabrics and films. The hand-held ultrasonic welding machine can replace different ultrasonic welding heads according to the size of the riveting point of the product to be welded and the welding requirements. It is fast and convenient, and the cost is much lower than that of a special automotive door plate ultrasonic welding machine, which meets customer needs. .


The ultrasonic welding machine converts a 50 / 60HZ current into a high-frequency alternating current through an ultrasonic generator, and inputs the electrical energy into the ultrasonic transducer to generate a mechanical motion with the same frequency. The mechanical motion is transmitted to the ultrasonic welding head through the amplitude modulator device, and the welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, energy is converted into thermal energy by friction, melting the plastic. The short-term pressure maintained on the workpiece after the vibration stops causes the two weldments to solidify in a molecularly linked manner. Generally, the welding time is less than 1 second, and the obtained welding strength is comparable to the body.
