High Power 20KHZ 2000W 3200W Ultrasonic Welding Machine For Metal Welding

Metal welding does not require flux and external heating, does not deform due to heating, has no residual stress, and does not require high pre-weld treatment on the surface of the weldment. Not only the same kind of metal, but also dissimilar metals can also be welded. It is possible to weld thin sheets or filaments to thick plates. Ultrasonic welding of good conductors has much less energy than current welding, and is often used for welding transistors or integrated circuit leads. When used for sealing welding of drugs and explosive materials, it can prevent general welding from contaminating drugs due to dissolved objects, and will not explode due to heat.
Working principle and characteristics
1. Ultrasonic metal welding machine uses the principle of ultrasonic high-frequency vibration friction to convert the energy of ultrasonic vibration into frictional energy and transfer it to the metal surface to be welded. When friction generates heat and pressure is applied to it, the metal structure molecule Fully activated to form a new type of device for fusion between molecular layers.
2. Features:
Microcomputer control, electronic tuning frequency, LCD display, continuously adjustable power, simple operation, stable and reliable work; firm welding, good consistency, weldment has the characteristics of firm welding surface, high strength, beautiful appearance, and environmental protection. Easy to operate, built-in electronic protection circuit, safe to use, used for similar welding of metals, can perform single-point or multi-point welding on non-ferrous metals; widely used in battery and hardware products industries.

Ultrasonic metal spot welding machine

Application range:
(1) The most common application areas of ultrasonic spot welding are semiconductor lead welding and IC circuit welding.
(2) Welding of battery pole pieces (welding of nickel tape + copper foil, nickel tape + aluminum tape, aluminum tape + aluminum foil, aluminum tape + aluminum cover, aluminum shell + aluminum nickel composite tape and other materials).
(3) Automotive electrical parts and other applications (welding of automotive wiring terminals, automotive wiring harnesses, motor terminals, relay sheets, electrolytic capacitor pole pieces, carbon brushes, heat sinks, etc.).
(4) Wires and famous electronic components, terminals, contacts, and connectors are fused to each other; wires are fused to each other, and one or more wires are fused together.
(6) Mutual melting of large heat sinks, heat exchange fins and honeycomb cores of famous household appliances and automotive products.
(7) Mutual melting of dissimilar metal sheets such as electromagnetic switches, non-fuse switches and other high-current contacts.
(8) Welding of non-crystalline alloy materials.
3. Features:
(1). The two objects to be welded are overlapped and joined by ultrasonic vibration and pressure to form a solid state, the joining time is short, and the joining part does not produce cast structure (rough surface) defects.
(2) Compared with the ultrasonic welding and resistance welding methods, the mold life is long, the mold repair and replacement time is less, and it is easy to realize automation.
(3) Ultrasonic welding can be carried out between the same metal and different metals, which consumes much less energy than electric welding.
(4) Compared with other pressure welding, ultrasonic welding requires less pressure, and the deformation amount is less than 10%, while the deformation of the workpiece in cold pressure welding is 40%-90%.
(5) Ultrasonic welding does not require pre-treatment of the welded surface and post-weld treatment like other welding.
(6) There is no need for external factors such as flux, metal filler, and external heating to handle ultrasonic welding.
(7) Ultrasonic welding can minimize the temperature effect of the material (the temperature of the welding zone does not exceed 50% of the absolute melting temperature of the welded metal), so as not to change the metal structure, so it is very suitable for welding applications in the electronic field.
