Abstract
The defect mechanism in horizontal steam generator tubes was analyzed, and the results of stress corrosion defects in the tube obtained by eddy current testing and metallographic analysis were compared. Furthermore, the reason of error due to eddy current testing was analyzed. The regularity of effect of different defect characters on testing results is presented.
