BACKGROUND ART
A compressor, as an important component of an aero-engine, is a mechanical device which transmits mechanical energy to a gas to compress a gaseous medium in a thermodynamic cycle of an engine so as to improve the pressure of the gas. A compressor disk is an im- portant part of the compressor, and conventional connections among disks are mechanical bolted connection and electron beam welding.
The mechanical connection results in large thickness and heavy weight of the compressor disk, so that the overall weight of the engine is increased, which is unfavorable to improving the thrust- weight ratio and performance of the aero-engine. The electron beam welding method features high thermal input, large welding defor- mation, high post-welding residual stress and high welding diffi- culty of dissimilar materials, so that it is difficult to com- pletely satisfy the manufacturing requirements of the design of the compressor disc of the aero-engine, and improvement of the overall performance of the aero-engine is severely restricted.
Friction welding can satisfy the welding requirements of the com- pressor disk, but workpieces constrained by the existing friction welding machine are prone to deviation due to torque action in the welding process, and as a result, the workpieces do not satisfy the welding requirements.
