Abstract

The measurement of buried defects is of great significance to the safety evaluation of pressure equipment. Ultrasonic shear wave testing is one of the most commonly used methods for defect size and location measurement. The test results are calculated from probe parameters, so errors in probe parameters will affect the measurement results. In order to study the influences of probe parameters errors on the results of ultrasonic shear wave testing of defect depth and height. First, the probability distributions of measured values were obtained through experiments. Secondly, Monte Carlo method was used to analyze the influence of probe parameter error on measurement results. Finally, the analysis results were verified by a test case. Studies have shown that the larger the refraction angle, the larger the probe parameter error, and the greater the impact on the depth and height defect measurement.
