Description

Technical Field

[0001] The present invention relates to the field of laser remanufacturing technology, and in particular to a wire-guided ultrasonic-assisted laser additive repair device and method. Background Art

[0002] Key components of high-end equipment, such as hot-end components of aircraft engines, ultra-supercritical turbine rotors and blades, are prone to structural and surface damage due to harsh service environments, resulting in shutdown or scrapping of high-end equipment. As a frontier field of manufacturing technology innovation, laser remanufacturing technology has profoundly changed the design and operation of high-end equipment. It is an important supporting technology for green remanufacturing and has been widely used in additive repair of components. However, due to the rapid solidification of metals during the laser remanufacturing process, remanufactured components are prone to pores and microcracks under extremely large temperature gradients and cooling rates, which seriously restricts the high-quality laser remanufacturing of components.

[0003] At present, some scholars have introduced ultrasound into laser forming to achieve defect suppression and performance improvement. However, due to the limitations of the ultrasound application method, only parts with specific shapes can effectively introduce ultrasound during the laser forming process. However, the remanufactured parts of high-end equipment usually have complex and irregular shapes and structures. The existing ultrasound application method is difficult to cooperate with the remanufactured parts, resulting in the inability to effectively introduce ultrasound during the laser remanufacturing process, thus limiting the application and promotion of ultrasound-assisted laser remanufacturing.
