The paper presents the results of studies of residual welding stresses in welded joints of large diameter pipes produced by the “sheet-pipe” process. The topography of distribution of residual stresses in circumferential and longitudinal direction in all the perimeter and length of the pipe is first established. The ways to reduce residual stresses in a pipe by means of local thermo-mechanical treatment of the welded joint and development of flux-cored welding wire on martensitic basis are also studied.
