Optimizing the Calibration Error of Refraction Angles in Ultrasonic Angle Beam Testing
Article

  • Mar 2020
Ultrasonic testing is a useful approach for quantifying the flaws in mechanical components. The height of the flaws in ultrasonic angle beam testing is closely related to the calibration value of the probe refraction angle. In order to reduce the calibration error, some ignored data during the traditional calibration process are reanalyzed and fuse...

... Rose introduced the refraction factor of ultrasonic wave in solid media [16]. Referred from Figure 1, the refraction angle can be calculated by , sin ...
Context 2
... bigger the refraction angle, the greater difference between WMF and AMF. When K2.5 probe was used, the effect was obvious, as shown in Figure 10. When BSCF are measured, the RS and RK depend on each other. ...
Context 3
... can be found from Table 9 that AMF is better than WMF. When K2.5 probe was used, the effect was obvious, as shown in Figure 11. Compared with the measurement of crack a using a K2.5 probe and the measurement of crack b using a K2.5 probe, the E (RS) in crack a is larger than the E (RS) in crack b. ...
