| 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. |
