Recently, the Shanghai YueQian Laser R&D team provided a tailor-made comprehensive laser re-manufacturing solution for the booster stage feedwater pump shaft of a nuclear power company, and received full praise from customers.

The pump shaft of the nuclear power booster stage feed water pump has been exposed to the working environment medium for a long time, corrosion defects appear on the surface of the pump shaft. In order to ensure the safe and stable operation of the water supply pump, the damaged parts of the pump shaft need to be repaired. YueQian Laser R&D team listened carefully to customer requirements and carefully formulated a pump shaft laser re-manufacturing plan: laser cladding process parameters, alloy powder selection, laser cladding processing control, precise repair shape of the pump shaft, etc. The entire process is strictly controlled and key technologies The customer's on-site supervision will lead to joint on-site identification.

The entire re-manufacturing of the booster stage feed water pump shaft goes through multiple steps, including: defect pretreatment, laser cladding, non-destructive testing, size confirmation, hardness confirmation, dynamic balance adjustment, run-out test, coaxiality correction, etc. Rigorous testing fully complies with nuclear power acceptance standards.

The re-manufacturing project of the nuclear-grade booster-stage feed water pump shaft is a successful case of YueQian laser re-manufacturing. In the future, the company will continue to increase the research, development and application of laser re-manufacturing in various fields.
