ultrasonic welding copper to aluminum

1) The two welded objects overlap and are joined by ultrasonic vibration compression to form a solid state. The joining time is short, and the joining part does not produce casting structure (rough surface) defects.

(2) Compared with resistance welding, ultrasonic welding has the advantages of long die life, less repair and replacement time, and easy to realize automation.

(3) Ultrasonic welding can be carried out between different metals of the same metal, which consumes much less energy than electrical welding.

(4) Compared with other pressure welding, ultrasonic welding requires less pressure and less than 10% deformation, while cold pressure welding requires 40% - 90% deformation of the workpiece.

(5) Ultrasound welding does not require pretreatment of the welded surface and post-weld treatment as other welding does.

(6) dealing with external factors such as soldering flux, metal filler, external heating and so on.

(7) Ultrasound welding can reduce the temperature effect of the material to a minimum (the temperature of the welding zone is not more than 50% of the absolute melting temperature of the welded metal), so that the metal structure does not change, so it is very suitable for welding applications in the electronic field. The fusion strength is high.

Near cold processing, workpiece annealing, no oxidation traces;

After welding, the conductivity is good, and the resistance coefficient is very low or near zero.

Low requirements for welding metal surface, oxidation or electroplating can be welded.

The welding time is short, without any flux, gas and solder.

No spark welding, environmental protection and safety. It is welded metal parts can not be too thick, solder joints can not be too large, need to pressurize.
