Non-destructive testing electromagnetic acoustic transducer (EMAT) technology Surface wave detection method

1 Scope

This standard specifies the general method for electromagnetic ultrasonic surface wave testing, which is used to detect surface openings and buried depths not less than the surface wave wavelength Surface discontinuity. This standard applies to surface wave detection of conductive or magnetic materials.

4 Method summary

4.1 Detection principle Electromagnetic ultrasonic surface wave detection uses a vertical permanent magnet bias magnetic field (shown in Figure 1) or a horizontal AC bias magnetic field to match the surface wave The probe of the reflex coil (shown in Figure 2) with a periodic wavelength, using the principle of electro-magnetic-acoustic interaction to excite and receive the ultrasonic meter on the surface of the material Surface wave. When surface wave encounters a discontinuity, reflection, diffraction or transmission attenuation occurs, and it is detected by the change of reflection signal, transmission signal or diffraction signal. Measure the position and size of the discontinuity. ......
