Abstract

A new method is presented for estimating residual stresses produced in a pipe made by surfacing weld. By focusing on the concept and the feature of inherent strain causing the residual stress, the proposed method has both the convenience of the Sachs method and the accuracy of the inherent strain method. The experiment for residual stress of a steel with brass cladding was done by both the Sachs and proposed method. The equation of the Sachs method for composite pipe was derived. The equation for the new method was obtained on the basis of the theory of inherent strain. It is found that the proposed method is useful for estimating residual stresses of pipe with cladding.
