38mm Diameter 28Khz Ultrasonic Vibration Transducer For Portable Spot Welding

38MM Diameter 28Khz Ultrasonic Welding Transducer for Portable Spot Welding

Description:

Ultrasound, as its name implies, exceeds the sound waves of conventional sound waves. Sound waves are longitudinal waves that can be felt by the human ear and have a frequency range of 16 Hz to 20 kHz. When the frequency of sound waves is lower than 16 Hz, it is called infrasound wave, and when it is higher than 20 kHz, it is called ultrasonic sound wave.

Ultrasonic application characteristics:

1. Beam characteristics

Because the wavelength of the ultrasonic wave is short, the ultrasonic ray can be reflected, refracted, and focused as well as the light. Obey the laws of geometric optics. That is, when the ultrasonic ray is reflected from the appearance of a substance, the incident angle is equal to the angle of reflection. When the ray passes through one substance and enters another substance of different density, refraction occurs, that is, the direction of the insertion is changed. The greater the difference in density of matter, the greater the refraction of the hot riveting machine.

2. Absorption characteristics

As sound waves propagate through various materials, the intensity gradually weakens as the propagation interval increases, because the material absorbs its energy. Regarding the same substance, the higher the frequency of sound waves, the stronger the absorption. Regarding a sound wave with a certain frequency, it absorbs the most harmful when it propagates in a gas, and absorbs weakly when it propagates in a liquid, and absorbs minimally when it propagates in a solid.

3. Ultrasonic energy transfer characteristics

Ultrasound has been used in various industrial sectors in the past, and the main point is that it has much stronger power than sound waves. Why is there a powerful power? Because when the sound wave reaches a certain material, the molecules in the material also follow the vibration due to the action of sound waves, the frequency of the vibration and the frequency of the sound wave, and the frequency of the molecular vibration determines the speed of the molecular vibration. The higher the frequency, the greater the speed.

The energy obtained by the material molecules due to vibration is determined by the square of the vibrational velocity of the molecules, in addition to the mass of the molecules. Therefore, if the frequency of the sound waves is higher, the higher the energy of the material molecules, the higher the frequency of the ultrasonic waves. It can be much higher than sound waves, so it can make the material molecules get a lot of energy; in other words, the ultrasound itself can supply enough power for the material.

4. Sound pressure characteristics of ultrasonic waves

When sound waves enter an object, the vibration of the material causes the material molecules to contract and dense, which will change the pressure on the material. Due to the vibration of the sound waves, the additional pressure phenomenon is called sound pressure.
