why use ultrasonic wave to check lose damages on bucket teeth?

　　During the production and using period for all of the ESCO bucket tooth, profession ESCO bucket tooth pin production manufacturer all like to choose ultrasonic wave to check the lose damages for these ESCO bucket tooth pin? But what is the working principle of ultrasonic wave? As general, ultrasonic wave can be divided into several different kinds, but during the actual lose testing process, profession ESCO bucket tooth pin production manufacturer said the pulse reflection type ultrasonic wave lose testing equipment is the most widely used.

　　To all of uniform materials, if it has several surface flaws problems, profession ESCO bucket tooth pin supplier said the continue property for materials would be reduced, so it will causes the auditory impedance has a big difference as well, but use the ultrasonic wave, we can make some reflection actions on the two different auditory impedance impurities, so according to the reflect back energy, we can confirm the final lose damage degrees.
