FIELD: machine engineering.
SUBSTANCE: shell elements are manufactured separately and their final hardening heat treatment is carried out. There are mounting surfaces at ends of a first element, and are made enclosing the seat surfaces, and at second and third elements-with enclosing mounting surfaces with dimensions providing guaranteed interference and connection tightness. At that the connection of shell elements is implemented with heating of the first element with enclosing mounting surfaces up to temperature providing preservation of strength properties of alloy the element is made of, and guaranteed exceeding of the dimensions of enclosing mounting surfaces of the first element above the reciprocal dimensions of the enclosing mounting surfaces of the second and third elements.
EFFECT: technological capabilities and increased geometric accuracy of the shells.
