Algorithms and applications of numerical simulation of temperature fields were created, the solutions for rectangular and circular plates and cylindrical shells of welding processes were found. The basic equations for modeling the kinetics of stress-strained state with the use of physical relationships of the strained type termoplastycity, the generalized considerations of possible unloaded elastic and unloaded with the occurrence of repeated plastic deformations were found. Iterative process according to the method of additional strains was developed for disclosure of physical nonlinearity. Algorithms and software for solving boundary value problems were obtained. We found the solutions based on the correlations of the strained type of welding processes for rectangular and circular plates and cylindrical shells.
