用涡流法和漏磁法进行了钢绞线查找焊点和探伤实验,在实验的基础上专门研制了涡流探伤仪和漏磁探伤仪。讨论了钢绞线涡流与漏磁探伤的关键问题,即振动和锌疤引起的噪声问题,描述了解决上述问题的关键技术。
Eddy current method and magnetic leakage method were used to search for solder joints and flaw detection experiments. Based on the experiments, eddy current flaw detectors and magnetic flux leakage detectors were developed. The key issues of eddy current and MFL testing on steel strand are discussed, namely the noise caused by vibration and zinc scar, and the key technologies to solve the above problems are described.
