FIELD: metal working by plastic deformation. SUBSTANCE: method consists in relative motion of crack edges by means of cyclic loading with smoothly reducing amplitude. Then, article is subjected to plastic deformation of its surface from both sides of emergence of crack to surface in its apexes, drilling of holes in crack apexes and on both sides of crack plane symmetrical to each other. Fasteners are installed in holes and tightened by pairs to directions running respectfully through holes in crack apexes and holes located in crack middle part. EFFECT: prolonged service life of article. 7 dwg, 1 tbl
