There is a direct relationship between pipe joint welding times and applied weld volume. This paper gives the computations necessary to define the locus for the branch saddle as a function of certain variables and of the optimized bevel angle. Joint configurations were studied for weld area variations for both fixed and optimized bevel angle configurations. Results demonstrated a considerable reduction in weld volume when the optimized volume was compared with the volume obtained using a fixed bevel angle.

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.

An efficient and reliable method for welding residual stress analysis is reported in this paper. The analysis method to calculate the residual stress using the iterative substructure method was developed and compared with a conventional one using a commercial finite element analysis code; comparisons were made for the analysis accuracy and the computational speed of the residual stress in a welded pipe joint. The residual stress distributions obtained by the both methods agreed well with each other. Moreover, it was clarified that the developed method could calculate the residual stress in a shorter computing time and could calculate the residual stress distribution much faster with nearly the same accuracy as the conventional method when the size of the welding structure was large.
