FIELD: metallurgy.
SUBSTANCE: invention relates to the technology of surface cold working for removal of strains immediately dealing with methods of weld joints strengthening treatment. The proposed method envisages mechanical treatment of weld joints with a pneumatic impact tool to produce indentations on the weld joints surface. Spacing between successive indentations is equal to no more than 0.4-0.5 of the indentation diametre.
EFFECT: improved fatigue strength of weld joints.
