spot welding machine

Handheld ultrasonic spot welding machine

Handheld ultrasonic spot welder uses ultrasonic plastic welding technology, through the ultrasonic transducer to convert high-frequency electrical energy into mechanical vibration energy, and then through the strip amplitude device will change the amplitude of mechanical vibration energy to the welding head. When the welding head is close to the processed product’s surface, the ultrasonic wave is automatically generated. The processed product’s surface does micro-amplitude high-frequency vibration, which is converted into heat by friction with the surface of the processed product, melting the processed product and then fusing it. Because the operation is spot welding, it is relatively more perfect for welding, and it is possible to get different effects of welding by changing the welding head.

When the ultrasonic wave ACTS on the thermoplastic surface will produce tens of thousands of high-frequency vibrations per second. The ultrasonic energy will be transferred to the welding area through the welding pieces, and local high temperatures will be generated. Due to the plastic’s poor thermal conductivity, the heat accumulated in the welding area, resulting in the rapid melting of the plastic surface, with a certain amount of pressure, it is integrated.

Handheld ultrasonic spot welding machines can be used for welding, riveting, spot welding of film, fabric, thermoplastic products, and inlay and crimping processes between metal parts and plastic parts.

Handheld Ultrasonic spot Welder Advantages

Handheld ultrasonic spot welding is easy to operate with a straight handle or pistol design.

The welding process can be controlled manually without using cylinder pressure.

Handheld ultrasonic spot welding is using a piezoelectric ceramic transducer; the output is stable and robust.

An automatic compensation circuit can be used to adjust power to achieve a consistent spot welding effect freely.

Handheld ultrasonic spot welding can be used for welding, riveting, spot welding of film, cloth, thermoplastic products, and inlaying and blanking processes between metal and plastic parts.

Welding surface no damage, no deformation, no scratch, and adhesive residue, not to use a lot of fixtures, flux, cement, reduce labor cost, can achieve the role of energy-saving and environmental protection.
