How it works: anything vibration will sound, any sound by vibration. The human ear can only perceive the sound within a certain range, this range of up to 18 000 (18K) Hz. Higher frequencies of sound we call it the ultrasound. Can produce high-frequency ultrasonic vibration, the use of this vibration, we can easily welding non-ferrous metals. Harness ultrasonic welding machine is a derivative of the ultrasonic metal welding machine equipment. Mainly used in automotive wiring harness, motorcycle wiring harness, welding copper, aluminum welding. So often called automotive wiring harness welding machine. 
 One of the advantages of ultrasonic wire welding machine is the most important is the lower temperature. Temperature generation is inevitable, it is only by the friction is only equivalent to the melting point of 1/3 or 1/2. In the low temperatures generated by the welding process, the generation and low-temperature annealing did not damage the wire insulation, metal wire to retain the original performance; In addition, lower temperatures can also mean that the thin metal welded to the thick metal , without causing damage to the thin metal. Are very important in the production of these harnesses.
