The high-speed rotor shaft is a core component of air compressors and steam turbines, operating under high-speed and high-load conditions for extended periods. The journal bearing areas are prone to uniform wear, localized scuffing, and even fatigue microcracks. Traditional arc welding repair methods involve high heat input, which can lead to shaft bending deformation and deterioration of the metallographic structure. By utilizing a 10 kW fiber laser equipped with a precision powder feeding system and special nickel-based alloy powder, the cladding process is completed by precisely controlling laser power (600-800W), scanning speed (8-12mm/s), and overlap rate (27.5%-30%), while maintaining the substrate temperature below 100°C. The resulting cladding layer is dense and defect-free, with stable hardness ranging from HRC53-56, achieving full metallurgical bonding with the substrate. Post-repair inspection confirms no defects through dye penetrant testing and ultrasonic testing, with dynamic balance precision meeting the G2.5 standard, fully satisfying the stringent balance requirements of high-speed rotors. This technology addresses the industry challenge of balancing repair quality and dimensional accuracy that traditional methods fail to achieve.
