detailed introduction
Ultrasonic spot welder is good:
  Ultrasonic waves are not only useful for welding, but also for a wide range of applications in other industries. For example, the application of ultrasonic waves in cleaning, how to complete ultrasonic cleaning, ultrasonic cleaning is the use of ultrasonic wave cavitation in liquid, acceleration and The direct inflow action directly and indirectly affects the liquid and the dirt, so that the dirt layer is dispersed, emulsified, and stripped to achieve the cleaning purpose. In the ultrasonic cleaner used, cavitation and direct flow are applied more.
  Cavitation: Cavitation is the transmission of ultrasonic waves to a liquid at a frequency of more than 20,000 compressions per second and a high-frequency transformation of pressure reduction. When the pressure is reduced, a phenomenon of vacuum nuclear group bubbles is generated in the liquid. When the compressive force acts, the vacuum core group bubbles are crushed by pressure to generate a strong impact force, thereby peeling off the dirt on the surface of the object to be cleaned, thereby achieving precision. Washing purpose.
  Straight inflow: The phenomenon that ultrasonic waves flow in the direction of sound propagation in a liquid is called straight flow. When the sound wave intensity is 0.5 W/cm2, the naked eye can see a straight flow, and a flow is generated perpendicular to the vibration surface at a flow rate of about 10 cm/s. Through this straight flow, the micro-oil dirt on the surface of the object to be cleaned is stirred, and the cleaning liquid on the surface of the dirt is also convected. The dissolved solution of the dissolved dirt is mixed with the new liquid, so that the dissolution rate is accelerated, and the handling of the dirt is very good. Great role. Acceleration: The acceleration produced by the liquid particles. For the ultrasonic cleaning machine with higher frequency, the cavitation effect is not significant. At this time, the cleaning mainly relies on the acceleration of the liquid particles to impinge on the particles to perform ultra-precision cleaning on the dirt.
