FIELD: engines and pumps.
SUBSTANCE: invention relates to production of gas turbine blades, for example, compressor hollow blades or gas turbine rotor and stator blades. Method of producing gas turbine engine hollow blade comprises the stages of producing the blade and blade foot. At the first stage, the blade is produced by jointing two parts together by diffusion welding so that the said parts form the aforesaid blade. Then, an additional element is produced to make the blade foot to be jointed to the aforesaid blade.
EFFECT: lower production costs.
