概要
西川 聡 Satoru NISHIKAWA Welding is widely used as a joint method of large structures. The residual stress which is the inevitable consequence of welding causes fatigue fracture or stress corrosion crackin g (SCC). In this study, the residual stresses of the dissimilar butt welding joint, which was fabricated between SUS316L and NCF600, were simulated using the finite element method. The distributions of the residual stress of the butt welding joint were anti-symmetry. The welded part had the large tensile residual stresses. In the welded part, the peened surfa ce had the large compressive residual stresses, which were measured using synchrotron X-rays. The distribution of the residual stress by welding contrasted with that after peening.
