| Abstract: | In this article, general method of discerning the metal part defect in eddy current NDT is introduced. While discussing the application of signal processing technic, it mainly discusses the principle of wavelet transform, studies its application in eddy current NDT, and also mainly analyses and compares BP and RBF algorithm in artificial neural network, introduces its application in eddy current testing defect. The development and application of eddy current NDT are also discussed. |
