In the Auto industry, ultrasonic puncture welding is not strange to us. Take the actual internal product as a reference, Share some ultrasonic puncture welding designs for internal and external Auto parts. There are some ultrasonic puncture welding technology, such as auto wheel arch welding, car door panel welding, Auto radar support welding, Auto spoiler welding and so on. 

Any company's ultrasonic welding machine has a center frequency, such as 20KHz, 40KHz, etc. The operating frequency of the welding machine is mainly the mechanical resonance frequency of the transducer, the booster, and the welding head (Horn). It was decided that the frequency of the generator was adjusted according to the mechanical resonance frequency to achieve agreement, so that the welding head worked in a resonant state, and each part was designed as a half-wavelength resonant body. Both the generator and the mechanical resonance frequency have a resonant operating range. If the general setting is ±0.5 KHz, the welding machine can work normally in this range. When we make each welding head, we will adjust the resonance frequency. To achieve the resonant frequency and design frequency error is less than 0.1 KHZ, such as 20KHz welding head, the frequency of our welding head will be controlled at 19.90-20.10 KHz, the error is 5‰.




1. Does the ultrasonic welding machine have any effect on the human body?

Ultrasound is not a source of radiation and generally does not harm the human body. We know that when an object vibrates, it emits a sound. The number of vibrations per second is called the frequency of the sound. Its unit is Hertz. The frequency of sound waves that we can hear in the human ear is 20 to 20,000 Hz. When the frequency of sound waves is greater than 20,000 Hz or less than 20 Hz, we can't hear it. Therefore, we call sound waves with a frequency higher than 20,000 Hz as "ultrasonic waves." The frequency of ultrasound that is usually used for medical diagnosis is 1 to 5 MHz. Ultrasonic waves have good directionality, strong penetrating ability, easy to obtain more concentrated acoustic energy, and have a long distance in water. Can be used for distance measurement, speed measurement, cleaning, welding, gravel and so on.
