概要
A guided wave testing is used in non-destructive inspections for pipe wall thinning and detects defects over a wide range of pipe. In this paper, first, hit/miss results are calculated from signal responses of the guided wave testing by using thresholds. The hit/miss results decide POD curves. We confirm the differences of the POD curves affected by the thresholds. Second, an optimal parameter tuning method which is effectively adjusted based on the condition of testing is integrated to the POD. The validity and effectiveness of the proposed method are shown through the experimental data.
