Abstract
The welding residual stress of a butt-welded pipe joint is evaluated, using inherent strain
analysis. The residual stress distribution is obtained in detail along the thickness direction. The
residual stresses are similar to values obtained by direct measurement on the specimen surface; as if
though direct measurement is not used for the inherent strain analysis. These results indicate that
inherent strain analysis is effective in evaluating through-thickness residual stress in primary piping
of girth welded joint.
