Copper Wire Welding by 20​Khz Ultrasonic Metal Wire Harness Welding Device 

Description: 

Ultrasonic copper alloy wire harness welding machine is to use the principle of ultrasonic friction to achieve surface welding of different media, which is a physical change process. First, the leading end of the wire must be processed to form a spherical shape, and the welded metal surface is first pre-heat treated; then the gold ball is combined with time and pressure to produce a sag deformation on the metal welding surface, so that the two media A reliable contact is achieved, and by ultrasonic vibration, a metal bond is formed between the two metal atoms under the action of atomic affinity, thereby realizing the welding of the gold wire lead. Gold wire ball bonding is superior to silicon-aluminum wire soldering in electrical and environmental applications, but the application range is relatively narrow due to the necessity of heating the weldment with precious metals. The welding time is short, the welding is not overheated or the welding penetration is not enough. The copper wire welding equipment does not need any flux, protective gas, and the welded joint is an alloy layer which is melted into one body. The chemical properties are stable and the conductivity is good. The resistance system and the material are original. The coefficients are basically the same. No splash, bright solder joints, no copper plating, no cracking at the terminals.

Advantages of QR-X2020A ultrasonic connecting harness and terminal welding machine welding

1. The two welded objects overlap, and are joined into a solid form by ultrasonic vibration and pressure bonding, the joining time is short, and the joint portion does not produce a cast structure (rough surface) defect;

2. Compared with the electric resistance welding method, the ultrasonic welding has a long service life, less mold repairing and replacement time, and is easy to realize automation;

3. Ultrasonic welding can be carried out between different metals of the same kind of metal, which consumes much less energy than electric welding;

4. Compared with other pressure welding, ultrasonic welding requires less pressure and the deformation amount is below 10%, while the workpiece deformation of cold pressure welding is 40%-90%;

5. Ultrasonic welding does not require pretreatment of the surface to be welded and post-weld treatment like other welding;

6. Ultrasonic welding can minimize the temperature effect of the material (the temperature of the weld zone does not exceed 50% of the absolute melting temperature of the weld metal), so that the metal structure is not changed, so it is suitable for welding applications in the electronics field.
