A new nondestructive method of evaluating welding residual stresses, the Bead Flush Method, has been proposed and its validity have been confirmed for simple butt-welded plates. In the previous work, a basic formulation by assuming axisymmetric condition is attempted for welded pipes and problems to be solved were made clear. In this study, further development of this method was attempted by conducting 3-dimentional formulation. In there, a reinforcement of weld was removed in a sequential manner and the formulation was attempted by incorporating that sequential process. It is shown that by adopting sequential process, accuracy to evaluate residual stresses has significantly improved compared with that of conventional method.
