20Khz 3000w Ultrasonic Sealing Metal Welding Machine for Solar Panel Welding
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.

There are two main methods for welding aluminum-plastic composite tube aluminum sheets: 1. Plasma welding 2. Ultrasonic welding
When using ultrasonic seam welding, the main points should be noted as follows:
1. It must be a machine with automatic frequency tracking. Because the temperature of the welding position is more than 100 degrees Celsius, the frequency of the welding head and the transducer assembly must decrease when working at such temperature. If there is no frequency automatic tracking, it will be different. The temperature is frequency modulated on the machine, which is easily damaged for machines that do not track the frequency automatically.
2. For machines without frequency automatic tracking, the amplitude consistency cannot be guaranteed at different temperatures.
Ultrasonic metal welding machine amplitude parameters:
Equivalent to the temperature of the soldering iron, the amplitude is a key parameter for the material to be soldered. When the temperature is too low, the welding will not be possible. If the temperature is too high, the raw material will be burnt or the structure will be destroyed and the strength will be deteriorated. Because each company chooses a different transducer, the amplitude of the transducer output is different. After adapting the different ratios of the horn and the horn, the working amplitude of the horn can be corrected to meet the requirements. Variable amplitude, functional amplitude, stepwise amplitude variation, etc. have a great influence on the ratio, and the front-to-back area ratio is proportional to the total ratio.
