The Origin Of Ultrasonic Metal Welding Machine

Ultrasonic metal welding machine (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. Ultrasonic metal welding machine can be widely used in thyristor chip leads, fast fuse melt holders, electrical lead terminals, lithium ion, and nickel Point and strip welding of pole pieces and tabs of hydrogen and nickel-cadmium batteries.
