The Shenyang Institute of Automation, Chinese Academy of Sciences successfully overcome the technical problems of laser additive repair of complex aluminum alloy thin-walled parts, and completed 2 batches of nearly 10 parts with high-performance and high-performance repair for an aviation company.
This technology is aimed at the technical problems of spare parts that cannot be repaired after the damage of aluminum alloy parts of a certain type of aircraft in China. The laser additive repair technology is adopted to realize the efficient repair of aluminum alloy parts. This technology improves the emergency maintenance level and spare parts accompanying support capability of a certain type of aircraft in China, and achieves reliability and extended life.
Aiming at problems such as the collapse of formed areas, strip defects between layers, and internal non-dense defects during the laser additive repair process of aluminum alloys, laser energy allocation and efficient powder transportation and capture, molten pool temperature and morphology control, defects and properties Key technologies such as regulation and control have achieved high-performance, defect-free integrated in-situ repair of aluminum alloy structural parts.
After years of technological accumulation and innovation, the Shenyang Automation Institute's process equipment and intelligent robot research room has gradually formed a four-in-one technology of high-end equipment, digital software, core processes and process detection in terms of high-performance laser additive manufacturing and efficient repair technology. system. Facing the problems of integrated manufacturing of high-performance and complex parts in the fields of aerospace, nuclear power, weapons, etc., it provides a full set of technical solutions to help the relevant fields to transform and upgrade and develop rapidly.
