The present disclosure provides a process and a device for the orbital friction welding of blades to the drum of an axial compressor. The process consists of holding the drum on a cradle via an indexing table, the cradle being able to pivot and vertically movable so as to present different regions of its outer surface parallel to the plane of orbital motion of the blade. The blade is held in the orbital motion device by a clamping device. The inner surface of the drum is braced by supports carried by a core fixed to the cradle. The drum comprises a series of protrusions which have a blade-shaped cross section. These protrusions form faying surfaces for the blades. The blades have a plate to ensure they are satisfactorily clamped by the clamping device. |
