Advantages of Ultrasonic Spot Welder

Customized Solutions

Most ultrasonic equipment needs to be customized according to the customer's actual use environment (laboratory or production line) and usage requirements. We can provide 10-100 watt laboratory equipment and 100 watt-3000 watt industrial-grade equipment.

Repair Service

Provide professional maintenance services. Even the best products need to meet stringent maintenance requirements. We support 24/7 maintenance services. Our technical engineers are ready to provide you with professional knowledge and technology at any time.

Requirements Testing

When you are not sure whether the product you have can be treated with ultrasound, you can mail the sample to us. We will use professional ultrasonic equipment to process it.

Core Customization

We can provide customized high-power transducers of 15K-120K. The transducers are made of aviation aluminum and PZT-8 piezoelectric ceramics. Through charge accumulation, the prestress is accurately obtained in real time to avoid the risk of high impedance and crystal cracking of the transducer.

High-Frequency Ultrasonic Spot Welder - 20kHz/40kHz Point Welding for Industrial Use

Product Description

  The handheld ultrasonic spot welding torch adopts ultrasonic plastic welding technology, converts high-frequency electrical energy into mechanical vibration energy through an ultrasonic transducer, and then changes the amplitude of the mechanical vibration energy through an amplitude modulation device and then transfers it to the welding head. When the welding head is close to the surface of the processed product, ultrasonic waves are automatically generated, and micro-amplitude and high-frequency vibration are performed on the surface of the processed product, friction with the surface of the processed product is converted into heat, melting the processed product, and then welding is carried out. Since the spot welding operation is performed, welding is relatively more perfect, and welding can be achieved by replacing the welding head.
