本文介绍了高灵敏高温超导超导量子干涉装置（HTS-SQUID）与超声导波相结合的新型管道远程无损评估（NDE）技术的基础研究。使用 HTS-SQUID 梯度计演示了钢管上声发射 (AE) 和超声波导波产生的磁信号的测量。为了将导波转换为磁信号，利用了粘在管道圆周上的磁化镍薄板的逆磁致伸缩效应。声发射传感器和带有缠绕线圈的替代磁化镍薄板被用作声发射和超声波导波发射器。 HTS-SQUID 梯度仪成功测量了由 AE 和超声导波产生的磁信号，该梯度仪设置在镍膜上方，剥离约 2 mm。
This paper describes basic research of a novel remote nondestructive evaluation (NDE) technique for pipes combining high-sensitive high-temperature superconductor superconducting quantum interference device (HTS-SQUID) and ultrasonic guided waves. Measurements of magnetic signals due to acoustic emission (AE) and ultrasonic-guided waves on a steel pipe were demonstrated using an HTS-SQUID gradiometer. To convert the guided waves into magnetic signals, the inverse magnetostrictive effect of a magnetized nickel thin plate glued around the pipe's circumference was utilized. An AE sensor and alternative magnetized nickel thin plate with wound coil were used as AE and ultrasonic-guided wave transmitters. Magnetic signals due to AE and ultrasonic guided waves were successfully measured by the HTS-SQUID gradiometer, which was set above the nickel film with a lift-off of about 2 mm.
