Flatness ultrasonic testing UT

Flatness ultrasonic testing ultrasonic testing is the use of ultrasound can penetrate deep into the metal material by entering a cross-section of another section is reflected at the interface edge features to examine a method parts defect, when the ultrasonic beam from the part surface It occurs when the reflected waves are inside pass by the probe to the metal, and parts defects encountered bottom surface to form a pulse waveform on the phosphor screen, according to the waveform of these pulses to determine the location and size of the defect. 1, when the ultrasonic wave propagation in the medium, in the quality of the interface have different reflection characteristics, in case of defects, defect size equal to or greater than the ultrasonic wavelength, the ultrasonic waves reflected on the defect, the reflected wave detector can be displayed ; such as the size of defects even less than the wavelength of the sound waves will not bypass the rays reflected; 2, good directional sound waves, the higher the frequency, the better directionality, in a very narrow beam of radiation to the medium, is easy to determine the defect location. 3, ultrasonic energy spread is large, such as the frequency of the energy 1MHZ (100 万 Hz) of the ultrasonic wave propagation, the equivalent of 100 times the same amplitude and frequency of 1000HZ (Hz) sound waves.
