Abstract
The paper presents the results of investigations on optimizing technological parameters of the process of pipeline circumferential reduction to induce a pattern of compressive residual stresses in the weld zone root. The problem of lowering the residual stresses under the die is solved by optimizing the die profile along the generatrix, as well as by applying deformable gaskets between the die and pipe.
Keywords: circumferential welded joints, decrease of residual stresses, deformational technology, optimum parameters of process
