Ultrasonic Welding Principle:Ultrasonic metal welding machine use ultrasonic frequency vibration principle to change ultrasonic vibration energy into friction energy and transfer to the metal surface to be welded ,while the friction produces heat under the pressure, the metal structure of molecules fully activation of the fusion between the molecular layer of the formation of the new equipment.
Ultrasonic spot welding is a well-developed and established production method for joining non-ferrous metals. Especially in the automobile industry, this reliable and trend-setting technology has been used in the production of wire harnesses for decades now. Ultrasonic metal welding is a cold, friction welding process, i.e. no liquid-melt phase occurs. The parts being joined are rubbed together at their contact surfaces under slight pressure.
The advantages of the machine;
△The welding is firm and reliable,and the resistance after welding is very small or close to zero,and the conductivity is good
△Equippde with high-performance ultrasonic metal spot welding power source,automatic tracking of transducer frequency with two control modes of time and energy
△Low requirements onthe terminal surface,no need to scrape off the oxide layer or electroplating layer
△The welding material does not need to be melted,does not change the material characteristics,and has no pollution
△It can realize welding between dissimilar metal,such as nickel+copper,copper+aluminum,nickel+aluminum,etc.
△The welding time is short,without any flux,shielding gas and filler
