| Abstract: | A method of eddy current inspection of hole defect has been presented in this paper. The defect is on iron steel, which is cut off from long pipeline carrying oil. A kind of double-coiled eddy current sensor has been designed. Through experiments, the feature of defect has been obtained, and a method of inspecting defect is set up. |
