Automotive high-voltage wire harness ultrasonic welding and crimping technology comparison
2024/05/20
Ultrasonic metal welding is a process of conversion of electrical energy into mechanical energy processing, in the welding process, there is no current flowing in the welded parts, there is no such as lasers, electric welding mode of destruction of molecular forms produced, due to the ultrasonic welding does not destroy the product molecules, through the high-frequency vibration of the products to make the product molecular chain fusion, so the strength is close to the product itself, there will be no electrical resistivity and heat conduction and so on, therefore, for the nonferrous metal materials For non-ferrous metal materials, it is a more ideal metal welding technology, for different thicknesses, different materials of metal plates and wire harnesses and cables, effective welding crimping, and welding surface is beautiful.
Advantages of ultrasonic metal welding: high fusion strength close to the product itself, does not destroy the product molecules conductivity is good, welding time is fast, energy saving does not require third-party additives, non-sparking, close to the advantages of cold state processing; Disadvantages: ultrasonic metal welding on the requirements of the material, the need for high purity of the metal to be welded, the thickness can not be too thick, generally less than or equal to 3mm ², the diameter of the wire squared does not exceed 120mm ². The actual need to customize the exclusive welding system according to the welding requirements, tension, resistance, section compression rate.
