Replacement Crimping Process by Qianronng 20Khz Ultrasonic Metal Welding Process
Description:
Ultrasonic welding of automobile wire harnesses is to weld a multi-strand or single-strand wire into a wire knot by ultrasonic action. The advantages are: good electrical conductivity after welding, very low or close to zero resistance coefficient; short welding time, no need for any flux, gas, solder.
Automotive wire harness ultrasonic welding should pay attention to:
1. It is best not to tin or galvanize the wire, although it can be welded in some cases, but the effect will be discounted.
2. Select the model according to the cross-sectional area of the wire.
3. Wire harness welders require good quality control software to make quality judgments for each solder joint.
4. Control mode adopts energy control mode

Advantage:
1. Ultrasonic welding can be performed between different metals of the same metal, which consumes much less energy than electrical welding. Ultrasonic welding requires less pressure than other pressure welding, and the deformation amount is less than 10%, while the workpiece deformation of cold pressure welding is 40%-90%.
2. Ultrasonic welding does not require pre-treatment of the surface to be welded and post-weld treatment as in other welding. Ultrasonic welding minimizes the temperature effects of the material and does not alter the metal structure, making it ideal for soldering applications in the electronics field.
3. 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. Compared with the electric resistance welding method, the ultrasonic welding has a long tool life, less mold repairing and replacement time, and is easy to automate.
4. It has the most advanced welding mode of time welding, deep welding and collapse welding, which is more suitable for high precision welding occasions. Double-column electric lifting body, easy to operate and high strength.
5. Fully English touch digital human-machine interface operation, with high speed, high efficiency and high precision. Linear ball slides ensure long-term, high-precision welding of the weld head.
The metal welding machine is also a semi-automated ultrasonic metal welding equipment that can use ultrasonic vibration energy to weld non-ferromagnetic metal materials. Metal welding machine equipment has a wide range of applications in the production of secondary batteries.
