One of the most important advantages of ultrasonic welding is its low temperature. The generation of temperature is inevitable. It is only generated by friction, which is only equivalent to 1/3 or 1/2 of the metal melting point. At the low temperature generated during welding, the metal wire retains its original properties due to the generation of annealing and low temperature without damaging the insulation of the wire; In addition, lower temperature also means that very thin metal can be welded to thick metal without causing damage to thin metal. These are very important in the production of wire harness.

Most of the metals used in electrical products have good thermal conductivity, which makes it difficult to weld by melting. Because the heat is quickly dissipated from the metal surface, more heat is needed to complete the welding. Ultrasonic welding has not encountered these problems. In fact, since no melting occurs, the energy of ultrasonic welding is only 1/30 of that of resistance welding. In other words, the ultrasonic welder with a power of 3KW can complete the work that resistance welding requires 90KVA, so the cost in the work is also obvious.
