Abstract
By using the numerical-experimental method based on the solution of inverse problems of the theory of shells with residual strains and the experimental data obtained by nondestructive methods, we determine the distribution of residual stresses near a circular weld in the main pipeline. The nonuniformity of the distribution of residual stresses under gauges of the measuring instruments is taken into account. The average characteristics of stresses with regard for the structural changes in the zone of thermal influence are found experimentally (by using measuring instruments).
