Abstract

Metal Magnetic Memory Technology (MMMT) can find out the residual stress concentration zone and provide early diagnosis for ferromagnetic structure components. The application of MMMT in welded joints inspection has been investigated and compared with the result of X-ray inspection in this paper. The applicability of MMMT in welded joints NDT is also analyzed. The experimental results show MMMT can find out the defects in the welded joints. It can also predict the dangerous zone in the welding joints.
