Abstract
We present the solution of the problem of evaluation of residual stresses in welded shells obtained with the help of a numerical-experimental method. By using the function that describes plastic strains, we apply this solution to the case of butt welding of steel pipes with a single-pass weld. The difference between the theoretical and experimental results does not exceed 10%. We also modify the approach to the evaluation of the width of the plastic zone in the numerical analysis of welding stresses by the method of Trochun.
