What is the high ultrasonic power of the ultrasonic metal welder?
The energy of ultrasound itself, the range of sound wave propagation. The ultrasonic metal welder is partially absorbed by the medium that propagates sound waves. As for how much this part of energy is absorbed, it depends on the nature of the medium. Generally, the energy of sound waves is absorbed more in gas, less energy is absorbed in liquids, and less energy is absorbed in solids (for example, in metals, quartz crystals are the medium). The higher the vibration frequency, the higher the energy absorbed by sound waves. more
From far to near, from far to far, the sound heard is a good example of sound wave absorption. As the distance increases, the high notes that disappear first, such as flute and flute, and then the baritone and viola; when the distance is far away, only the bass at the bottom of the drum can be heard. Ultrasound also applies to this platform: frequency The higher, the stronger the absorption. The shorter the distance the ultrasonic wave travels.
The upper limit of ultrasonic vibration of ultrasonic metal welder is about 100 billion Hz. Ultrasonic waves are absorbed at a higher frequency than this frequency. According to the above instructions, it can be estimated that there is no sound on the surface of the acoustic transmitter, but this upper limit has not been reached. At present, the frequency of ultrasound is about 1 million Hz in actual research by Soviet scientist CR Sokolov.
