ultrasonic spot welding machine

Ultrasonic metal spot welding machine uses the principle of ultrasonic frequency vibration to convert ultrasonic vibration energy into friction energy and transfer it to the surface of the metal to be welded to achieve the purpose of welding.
The machine has built-in electronic protection circuit, which is safe to use. It is widely used in metal products industry.
Ultrasonic energy has been used to join metal materials for decades. In ultrasonic metal welding, dissimilar materials are joined together without the use of applied heat or electric current passing through components.
Ultrasonic energy can weld through contaminates to create a clean seal while providing increased quality and control. To achieve a high-quality seal, one part is held stationary while the second part is compressed beneath a vibrating horn. The material reaches a plastic state where molecules mix between the two parts, bonding the materials.


1. High-quality ultrasonic transducer, strong power, good stability.

2. Good conductivity and resistivity very low or almost near to zero.
3. Oxidation or plating metal can be welded.
4. Short weld time, no need additional flux, gas, solder.
5. No welding sparks, environment protection and safety.
6. Without the need for frequent replacement of amplifier due to stepless adjustment of the amplitude.
7.Low energy consumption, high efficiency, no distortion, no pollution, welding firm, and convenient operation.
8. Welding material does not melt non-fragile metal properties.
9. Good conductivity and resistivity very low or almost zerot.
10. Pairs of welding metal surfaces that require low, oxidation or plating can be welded.
11. No welding sparks, environmental protection and safety.

Working Principle

ultrasonic spot welder
The ultrasonic welding process converts electrical energy into mechanical vibrations causing the metals to join. In the ultrasonic stack, the converter transmits the energy through the booster causing the horn to vibrate. The converter is made up of piezoelectric ceramic disks that expand and contract at the same frequency of applied electrical energy. The booster increases or decreases the amplitude of the vibrations to provide the optimum amplitude for the material, size and type of assembly.
