FIELD: machine engineering.
SUBSTANCE: method for producing a hollow blade of a turbomachine comprises forming blade back and trough elements by imparting a predetermined profile and dimensions to the plates, fixing them and providing predetermined profile and dimensions of the blade and their subsequent integral connection between each other. At that, the blade back and trough elements are connected to each other through additional metal elements forming an inlet and oulet blade edges which correspond to profile and sizes of inlet and outlet blade edges and have cavities providing conjugated connection to the blade back and trough elements.
EFFECT: use of various methods for connecting blade elements and increase wear resistance of the blades.
