“Characteristics and advantages” of knowledge points of ultrasonic wire beam welding machine

Pros: an important advantage of Ultrasonic welding is the low temperature. Temperature is inevitable, it is only caused by friction, equivalent to only 1/3 or 1/2 of the melting point of the metal. At the low temperature produced by the welding process, due to the generation of annealing and the low temperature did not destroy the insulation of the wire, the metal wire retained its original performance, lower temperatures also mean that it is possible to weld very thin metal to thick metal without causing damage to the thin metal. These are very important in the production of wire harnesses. Most metals used in electrical products have good thermal conductivity, making it difficult to weld by melting. Because heat is quickly released from the metal surface, more heat must be applied to complete the welding. The Ultrasonic welding didn't have these problems. In fact, since no melting occurs, the Ultrasonic welding's energy is only one-thirtieth that of resistance welding. In other words, with the power of 3KW ultrasonic welding machine can complete resistance welding requires 90KVA to complete the work, so the cost of work is also obvious. The Ultrasonic welding is a mechanical process. There is no current flowing through the workpiece, so the conductivity of the metal has no effect. The metal surface is usually attached to pollutants and oxide layer, the use of ultrasonic wire beam welding machine, without pre-treatment of the metal surface, ultrasonic vibration can be directly attached to the debris broken after removal. Another important advantage of Ultrasonic welding is the long life of the work piece. The welding head of the ultrasonic wire harness machine has 4 working faces, which reduces the cost of later maintenance of the equipment.
