The relationship between the flaws and response characteristics of eddy current signals was analyzed and studied by means of the design of minor diameter transducer for eddy current inspection and the features of the impedance diagram for the flaws such as cracks were analyzed by comparison which verified determining defects and technical advantages on the basis of impedance diagram magnitude and phase analysis. The results show that the minor diameter transducer has the characteristic of detection fast , high sensitivity, accurate results.
