- 摘要:
- 通过对大批量的钛合金管材进行涡流检测,从涡流检测原理以及影响因素等方面分析了缺陷信号、噪声信号的产生以及差异,通过多次调试试验得到了各种规格管材的检测参数,其中对检测结果影响比较大的频率、增益进行了多次对比试验,得到了最佳参数范围,为管材的可靠性判断提供了依据。
- Abstract:
- Based on the eddy current testing for a mass of Ti alloy ducts, the generation and difference of defect signal and noise signal are analyzed in terms of eddy current testing principle and influencing factors. Testing parameters of ducts with various sizes were obtained through several times of debugging tests. Several comparison tests on frequency and gain were conducted because of their significant influence on testing results. The optimal parameter range was acquired for reliability judgement of the ducts.
