Application Of Ultrasonic Metal Welding Machine in The Automotive Industry

Taking Automotive Wire Harnesses as an Example
Ultrasonic metal welding machine uses ultrasonic technology as the core technology and can be used for welding non-ferrous metals such as nickel, tin, and aluminum. It is suitable for multiple industries such as automobiles, hardware, and communication, and is a widely used metal welding equipment. Among them, ultrasonic metal welding machine is a typical application for welding automotive wire harness terminals
Car wiring harness refers to contact terminals made of copper as raw material, used for connecting wires and cables, while external plastic insulators or metal shells are used for circuit assembly. Car wiring harness is an important component of the car, playing the role of the main body of the car circuit network. Without car wiring harness, car circuits would no longer exist.
At present, the use of ultrasonic technology for automobile wire harness welding is a commonly used welding process. Its welding principle is to use ultrasonic waves to act on the surface of two metal workpieces, promote the fusion of molecules on the surface of the workpieces, achieve the purpose of welding, and complete the welding. The use of ultrasonic metal welding equipment has multiple advantages:
1, During the welding process, there will be no sparks generated, and the welding process is environmentally friendly and pollution-free.
2, The time period required for welding, the welding efficiency is effectively improved to ensure output.
3, When welding, welding operations can be completed without the need for flux, solder, or other auxiliary fluxes.
4, There are no strict requirements for metal materials, and oxidized or electroplated metals can be welded.

5, The welded product has good conductivity and low resistance coefficient.
6, The entire welding process is close to cold processing, with no annealing of the workpiece and no traces of oxidation.
