Ultrasonic rolling welding machine welding principle is to generate 20KHz (or 15KHz) high-voltage, high-frequency signal from the generator, through the conversion system, the signal is converted into high-frequency mechanical vibration, applied to the workpiece of metal products, through the surface of the workpiece and in the molecule The friction between the two causes the temperature transmitted to the interface to rise. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is rapidly melted, and then filled in the gap between the interfaces. When the vibration stops, the workpiece is simultaneously cooled and shaped under a certain pressure. Then, the welding is achieved.
