| Abstract: | The application limitation of traditional eddy current testing has been discussed in detail, new eddy current technologies such as far field eddy current testing, phase array technology and magnetic saturation and so on were introduced. The far field eddy current testing system for trial was developed. Testing result showed that inspecting corrosion situation of oil storage tank bottom in eddy current testing was possible, the quality and improvement of probe affected the trial result greatly. In order to effectively inspect all kinds of defects and to improve the sensitivity and accuracy of inspection, the far field eddy current testing system should be improved further. |
