Application Principle of 1. Ultrasonic Metal Welding Machine

Application of Ultrasonic Metal Welding Machine has 20kHz -40kHz. Its principle is to weld the same or different non-ferrous metal materials by using the energy of ultrasonic high-frequency mechanical vibration. During the welding process, neither current nor high-temperature energy is transmitted to the workpiece, but reciprocating vibration is carried out on the surface of the workpiece at a high frequency of 20kHz -40kHz, and the corresponding pressure is applied to the workpiece to form a solid-state combination between the workpieces to achieve the welding effect. Ultrasonic metal welding used in lithium batteries is to weld conductive materials with different poles. The welding requirements are relatively high. The use of ultrasonic technology for welding is a better welding equipment for battery manufacturers. The main materials are (nickel sheet and copper sheet, aluminum Strip and aluminum foil, aluminum-nickel composite tape and aluminum shell, etc.).

Advantages of 2. ultrasonic metal welding machine

1), the welding material does not melt, and the metal characteristics are not fragile.

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

3), low requirements for welding metal surface, oxidation or electroplating can be welded.

4), welding time is short, without any flux, gas, solder.

5), welding without sparks, environmental protection and safety
