Abstract: The paper analyzes the changes in the structure, phase composition and values of internal stresses in the samples St3sp steel’s under plastic deformation. We compare the results of the study sample with artificial defects and defect-free samples, performed manual arc welding and welding the modulated current. Settle limit values value of plastic deformation during testing of technical devices for high pressure this welded compounds.

Key words: welding the modulated current plastic deformation artificial defects field internal stress dislocation density
