Abstract

Ultrasonic testing (UT) and eddy current testing (ECT) are the effective nondestructive testing methods which are widely used in many practical fields, such as machinery, power system, airplane and petrochemical industries. Each method has its advantages and disadvantages in the practical application. We use data fusion method that is based on the Dempster-Shafer evidence theory and the fuzzy inference and the data from eddy-current testing and ultrasonic testing to evaluate the defects in the conductive structure, and better results have been obtained.
