Ultrasonic welding principle of spot welding machine is produced by the generator 20KHz, 28KHz, 35KHz high voltage, high frequency signal, can by changing the system, the signal is converted to high-frequency mechanical vibration, and on the plastic workpiece, through the surface and inner friction between the molecules and make the transfer to the interface temperature, when the temperature reaches the melting point of the workpiece itself, the workpiece interface rapidly melting, and then fill in the space between the interface; When the vibration stops and the workpiece is cooled to a certain pressure, the perfect welding is achieved.
