Ultrasonic metal welding is appropriate for the assembly of similar and dissimilar non-ferrous metals.
The primary advantage of this welding technique is that it provides exceptionally short welding times, no filler metals requirements, very low electrical contact resistance and helium-tight welds. Surfaces that are suitable for this type of welding are limited to small areas and restricted to points, line or circular weld patterns.
Altrasonic series welds stranded, braided and magnet wires to create a wire splice, wire crimp or a battery cable splice. The connections it produces are used in the automotive, aircraft, computer and consumer electronics industries, as well as other process control and industrial instrument applications. It is most commonly used in the production of wire harnesses.
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.
