1800W 20KHZ Ultrasonic Welder Fast Lithium Battery Welding Copper With Drivers Generator

Ultrasonic wave metal spot welder: it is similar to friction welding, but different. Ultrasonic welding time is very short, and the temperature is lower than recrystallization; It is also different from pressure welding because the applied static pressure is much smaller than that of pressure welding. It is generally believed that in the initial stage of the ultrasonic welding process, the oxide on the metal surface is removed by tangential vibration, and the process of repeated micro welding and destruction of the protruding part of the rough surface increases the contact area, at the same time, the temperature of the welding area increases, and plastic deformation occurs at the interface of the weldment. In this way, under the action of contact pressure, when they are close to the distance where atomic gravity can act, the solder joint is formed. If the welding time is too long or the ultrasonic amplitude is too large, the welding strength will be reduced or even damaged. ultrasonic metal welding machine is an advanced high-tech equipment that converts high-frequency electric energy into mechanical vibration energy through a Ultrasonic Transducer and acts on the workpiece, generating high-frequency friction between two workpiece surfaces, until the two workpiece surfaces are heated and welded together. It can perform spot and strip welding on thin materials of conductive metals such as copper, silver, chromium and nickel, and can be widely used in spot and strip welding of silicon controlled chip leads, fast fuse melt sockets, electrical lead terminals, lithium ions, nickel hydrogen, nickel cadmium battery electrode lug, etc.
