本文旨在利用电磁声换能器对管壁减薄进行定量无损评价。实验中提供了304不锈钢半椭圆试样。首先，使用所提供的测试样品示出测量和模拟实验的结果。各种模拟结果与实验室实验结果吻合较好。其次，脉冲回波信号相对于管壁腐蚀几何形状的灵敏度进行了研究。最后，我们的规模化方法的可行性研究进行了总结，以评估FAC和早期的LDI测试样品。
This paper aims at a quantitative nondestructive evaluation of pipe wall thinning using an electromagnetic acoustic transducer. Type 304 stainless steels sample specimens that are fabricated by a semi ellipse were provided for our experiments. First, results of measurement and simulation experiments are shown using the provided test samples. The variety of simulation results showed good agreement with laboratory experimental results. Second, the sensitivity of pulse echo signals with respect to corrosion geometry of pipe wall is investigated. Finally, the feasibility studies of our sizing methodology are summarized for evaluating FAC and early LDI test samples.
