FIELD: mechanical engineering.
SUBSTANCE: invention refers to mechanical engineering and can be used in blades manufacturing for turbine machines. At least two primary external components are manufactured. These components are welded together by means of diffused welding. As the result preliminary blade shape is obtained. This has feather element limited by planes and root element. The first primary component contains feather area and material reserve projecting relative to preliminary shape plane at one of its ends. Material reserve is intended to create root element of preliminary form.
EFFECT: cost reduction for hollow blade manufacturing is provided.
