FIELD: process engineering.
SUBSTANCE: inventions may be used in diffusion joints of components with nonplanar shape, particularly, aircraft engine parts. Firs component of pressure side with first joint surface and second component on rarefaction side with second joint surface are arranged to make butt joint on mandrel. Outline of mandrel first surface complies, at least, partially, with first component surface portion while mandrel second surface outline is aligned with second component portion. Components are jointed together at separate positions along their lengthwise line. First and second components are positioned together with mandrel at die assembly. Said surfaces are jointed by diffusion in furnace by applying uniform pressure along joint surfaces. Male and female dies may be jointed together by multiple fasteners with lower thermal expansion factor. Flexible pneumatic conveyor is arranged between male or female die and one of joint surfaces.
EFFECT: higher quality of joint.
