抄録

The internal residual stress distribution that resulted from welding a 4-inch-diameter carbonsteel pipe butt joint was evaluated using several methods and the results were compared. The analytical evaluation methods used were inherent strain analysis and thermal elastic plastic analysis, and the experimental methods were X-ray diffraction and strain gauge for the surface residual stress, and neutron diffraction for the internal stress. The residual stress distributions determined using the various methods agreed well with each other, both for surface stress and internal stress. The characteristics of the evaluation methods were summarized and it was found the most suitable method for any particular situation can be selected by considering the evaluated location and the operating conditions of the object to be evaluated.
