The purpose of the work is to calculate the residual stress-strain and microstructural states of sheet and thin-walled cylindrical parts during surfacing, to compare the results of calculations with experimental data, to formulate recommendations regarding the parameters of the modes and materials of surfacing. Numerical modelling of surfacing processes was carried out using a finite element technique, a unified model of viscoplastic flow, the theory of growing bodies, as well as thermokinetic diagrams for calculating microstructural transformations. New results were obtained concerning the stress-strain and microstructural current and residual states, as well as the distortion of sheet and thin-walled cylindrical parts during surfacing. The significant influence of microstructural transformations and conditions of fixing on the residual deflection of parts was established. Satisfactory matching of calculated and experimental data was obtained. Recommendations for the surfacing of thin-walled elements were formulated.
