Ultrasonic metal welding is the product of modern industrial progress. Through this welding technology, the efficiency can be greatly improved. Its working principle is to connect the same metal or different metals through the damping vibration kinetic energy of ultrasonic frequency.

During ultrasonic welding of metal, neither current is transmitted to the workpiece nor high temperature heat is applied to the workpiece. Only under static working pressure and relatively limited temperature, linear vibration and kinetic energy are converted into friction work and deformation energy ratio between workpieces.

The fusion between connectors in the metallurgical industry is a kind of solid welding maintained without melting the butt weld. Therefore, the phenomenon of spatter and air oxidation during resistance welding is reasonably eliminated.

The metal welder can spot weld, multiple weld and short strip weld the thin strip or thin plate of copper, silver, aluminum, nickel and other colored metal.

This welding technology can be widely used in the welding of the bi-directional thyristor leads, fuse segments, household appliance leads, lithium electrode segments and electrode lugs.
