2000W 20KHZ Ultrasonic Metal Welding Machine For Soldering Tin And Nickel

Ultrasonic wave metal spot welder (Ultrasonic wave metal spot welder): It is similar to friction welding, but there are differences. Ultrasonic welding takes a short time and the temperature is lower than recrystallization; it is also different from pressure welding because the applied static pressure is higher than the pressure The welding is much smaller. It is generally believed that in the initial stage of the ultrasonic welding process, the tangential vibration removes the oxides on the metal surface, and the protruding part of the rough surface produces repeated micro-welding and destruction, which increases the contact area and increases the temperature of the welding zone. High, plastic deformation occurs at the interface of the weldment. In this way, under the action of contact pressure, when they approach each other to the distance at which atomic gravity can act, a solder joint is formed. The welding time is too long, or the ultrasonic amplitude is too large, which will reduce the welding strength or even destroy it. Ultrasonic metal welding machine is an advanced high-tech equipment that converts high-frequency electric energy into mechanical vibration energy through a transducer and acts on the workpiece, generating high-frequency friction between the surfaces of the two workpieces, until the surfaces of the two workpieces are heated and welded together . It can perform spot and strip welding on thin materials of conductive metals such as copper, silver, chromium-nickel, etc. It can be widely used in thyristor chip leads, fast fuse melt sockets, electrical lead terminals, lithium ion, nickel Point and strip welding of pole pieces and tabs of hydrogen and nickel-cadmium batteries.

Popularity and classification
Ultrasonic spot welding machine, ultrasonic metal welding machine, ultrasonic metal spot welding machine, ultrasonic welding machine, aluminum-nickel welding machine, polymer battery positive electrode spot welding machine, lithium battery negative electrode spot welding machine, aluminum to nickel spot welding machine, amorphous silicon Spot welding machine etc.
Features of metal welding
There is no need for flux and external heating, no deformation due to heating, no residual stress, and low requirements for pre-welding 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.
