Is The Ultrasonic Welding Machine Harmful To People?

Ultrasound is not a source of radiation and is generally harmless to the human body. We know that when an object vibrates, it emits sound. The number of vibrations per second is called the frequency of the sound, and its unit is hertz. The frequency of sound waves that we can hear is 20 to 20,000 Hz. If the vibration frequency of the sound wave is greater than 20000 Hz or less than 20 Hz, we will not be able to hear it. Sound waves with a frequency higher than 20000 Hz are called "ultrasound".

      The frequency of ultrasound usually used for medical diagnosis is 1 to 5 MHz. Ultrasound has the characteristics of good directionality, strong penetrating ability, easy to obtain concentrated sound energy and long-distance in water. It can be used for distance measurement, speed measurement, cleaning, welding, stone crushing, etc. It has obvious effects in medicine, the military, industry, and agriculture. High-power-focused ultrasound can be used to treat tumors. It can rapidly increase the temperature of the target area tissue to above 70°C within 0.5 seconds, causing the intracellular protein to rapidly appear coagulation. Necrosis (the critical point of lethal temperature for tumor cells is 42.5~43.0°C, while that of normal cells is 45°C. For liver tissue, a local temperature exceeding 58°C can cause tissue coagulation necrosis).

       The local sound intensity is as high as more than 10,000 watts/cm2, of course, it may damage the local normal tissues, and precise positioning is required. In terms of ultrasound protection, it is necessary to pay attention to people suffering from hearing diseases and neurological disorders not to work around such equipment. High-intensity ultrasound equipment should be shielded to block ultrasound.

        At present, there is no exact data to prove that the ultrasonic welding machine is too harmful to the human body, but the only disadvantage is that you must wear earplugs when welding to prevent long-time work and affect your hearing!
