FIELD: plastic metal working: manufacture of shell members for welded structures.
SUBSTANCE: proposed method of forming double curvature sheet parts by application of successive local bending forces at one or several passes includes preliminary cutting out of middle part of blank is place of expected maximum thinning. Then parts of blank are formed separately after which integrity of part is restored by welding.
EFFECT: improved quality of parts owing to reduction of thinning.
