The principle of an ultrasonic metal welding machine is to use an ultrasonic generator, transducer, and amplifier to convert electrical energy into high-frequency mechanical motion.

Through the welding head, the vibration energy promotes friction, deformation energy, and limited heating between metal welding components. With the help of surface melting, a solid-state welding is achieved. Therefore, it effectively overcomes the phenomena of splashing and oxidation generated during resistance welding.

It is green and environmentally friendly without any pollution. Ultrasonic metal welding machines can perform single point welding, multi-point welding, and short strip welding on fine wires or thin sheet materials of non-ferrous metals such as copper, silver, aluminum, and nickel.

They can be widely used for welding thyristor leads, fuse strips, electrical leads, lithium battery electrodes, and lugs.
