Aeroengine blisk repair

Aeroengine blisk repair

Product Description：

The current manufacturing method of the blisk is forging, which has a high cost and long cycle. Forged blisks may also have some metallurgical defects. The aero-engine blisk is prone to defects such as blade tip wear and cracks during use. In most cases, it is directly scrapped because it cannot be repaired. The cost of direct replacement of the integral blink of an aero-engine is very expensive. The laser additive manufacturing technology can control the deformation well, and achieve the repair accuracy that cannot be achieved by the traditional surfacing method. The use of laser additive manufacturing technology can realize the direct forming of the whole blisk in a short time, which can save costs and improve production efficiency in a large procedure.
