1. Application principle of ultrasonic metal welding machine

There are 20KHZ——40KHZ in the application of ultrasonic metal welding machine. The principle is to use the energy of ultrasonic high-frequency mechanical vibration to weld the same or different non-ferrous metal materials. During the welding process, no current is transmitted to the workpiece, nor to the workpiece. The workpiece transmits high-temperature energy, but in the workpiece, the high frequency of 20KHZ-40KHZ is cyclically vibrated on the surface of the workpiece, and the corresponding pressure is applied to the workpiece to form a solid bond between the workpieces to achieve the welding effect. Ultrasonic metal welding applied to lithium batteries is to weld different conductive materials at the two poles. The welding requirements are relatively high. Ultrasonic welding is a better welding equipment for battery manufacturers. The main materials are (nickel and copper, aluminum Strip and aluminum foil, aluminum-nickel composite tape and aluminum shell, etc.).

2. Advantages of ultrasonic metal welding machine

1) The welding material does not melt, and the metal is not fragile.

2) After welding, the conductivity is good, and the resistivity is extremely low or almost zero.

3). Low requirements on the surface of the welded metal. Both oxidation and electroplating can be welded.

4) The soldering time is short, without any flux, gas, or solder.

5), welding without sparks, environmental protection and safety
