FIELD: non-positive displacement machines or engines.
SUBSTANCE: method comprises making light-weight blade (1) for the turbine machine having blade (40) made of metallic alloy and provided with space (70) at one of its side (50) covered with lid (80). Lid (80) whose edge (85) is connected with the remainder portion of blade (40) by welding provides aerodynamic continuity of side (50a). Weld (100) originates at side (50a) and enters blade (4) at a depth that at least equal to the thickness of the lid edge. The weld is made by friction welding.
EFFECT: enhanced reliability and reduced cost.
