摘要: 设计制作了钛合金管材对比试样,并采用穿过式涡流、阵列涡流和旋转涡流3种方法对其进行检测。从检测灵敏度、周向分辨力、轴向分辨力、检测盲区和胀接区检测能力等方面对检测结果进行了比较。结果表明,阵列涡流的综合检测能力优于穿过式涡流和旋转涡流的,在钛合金换热管的涡流检测中有广阔的应用前景。

Abstract: The contrast specimens of titanium alloy pipe are designed and manufactured, and they are tested by three methods: through eddy current, array eddy current and rotating eddy current. The detection results are compared from the aspects of detection sensitivity, circumferential resolution, axial resolution, detection ability of detection blind area and expansion area. The results show that the comprehensive testing ability of array eddy current is better than that of through eddy current and rotating eddy current, and the former one has a broad application prospect in the eddy current testing of titanium alloy heat exchange tubes.
