On May 14, 2020, Chengdu Qingshi Laser Technology Co., Ltd. (hereinafter referred to as “Qingshi Laser”) held a scientific and technological achievement appraisal meeting on “Mobile Laser Additive Manufacturing Equipment and Key Process Technologies for Energy Equipment” at the Sichuan Machinery Research and Design Institute held.

Chengdu Qingshi Laser Technology Co., Ltd. (hereinafter referred to as “Qingshi Laser”) held a scientific and technological achievement appraisal meeting on “Mobile Laser Additive Manufacturing Equipment and Key Process Technologies for Energy Equipment” at the Sichuan Machinery Research and Design Institute. An evaluation committee composed of mechanical power equipment industry experts from Sichuan Machinery Research Institute, Sichuan Aerospace Technology Research Institute, the 5719th Factory of the Chinese People’s Liberation Army, Sichuan University, Southwest Jiaotong University, etc. conducted a professional evaluation of the project results.

Dr. Qi Huan, chairman and general manager of Bluestone Laser, gave a detailed report on the project results at the meeting. The experts of the evaluation committee unanimously determined that the overall project results reached the internationally advanced level and the key technologies reached the internationally advanced level through listening to the results report, document review, and on-site defense. leading level.

As we all know, energy equipment is related to national energy security. The maintenance of its core components has the characteristics of a harsh environment, large size, difficulty in disassembly and transportation, high replacement cost, long cycle, and large losses. For a long time, on-site emergency repair and life extension issues have caused headaches for scientific and technological workers and enterprises. Repair materials, equipment, and key processes have been blocked by foreign countries for a long time. When the General Secretary inspected the Three Gorges Project, he emphasized: “A great power and important weapon must be in our own hands.” However, there is a huge risk of failure in the task of repairing and strengthening power stations. No one in the domestic laser industry can do it, and no one dares to do it. Faced with the challenge, Bluestone Laser decisively took on the challenge.

Dr. Qi Huan pointed out that this project is in accordance with the national “Made in China-2025″ Energy Equipment Implementation Plan” and is oriented to the actual needs of the energy field. Since 2014, starting from the on-site emergency repair problems of the Three Gorges Hydropower Station, Chengdu Bluestone Laser Technology Co., Ltd. took the lead and cooperated with Nanjing Huirui Optoelectronics Technology Co., Ltd. and other units to conduct in-depth research on equipment, software, processes, evaluation and applications, comprehensively tackle the key problems, and put forward a new idea of “mobile laser additive enhancement”, and finally Developed the first mobile laser additive manufacturing equipment for in-situ laser additive strengthening of large-scale equipment, and successfully manufactured key flow-passing components such as the runner chamber, runner body, and runner blades in the generator sets of the Three Gorges and Gezhouba Hydropower Stations. , as well as the additive repair and strengthening application of the silver conductive coating on high-current aluminum busbar joints, it has solved the long-standing problems of on-site emergency repair and life extension of large equipment, achieving the effect of “repairing the old and making it newer”, and realized the upgrading of key components of energy equipment. Autonomous protection.

At the evaluation meeting, experts highly affirmed the research work of the bluestone laser project. Professor Yin Guofu, a professor and doctoral supervisor at the School of Manufacturing Science and Engineering of Sichuan University and an academic and technology leader in Sichuan Province, spoke highly of the results of the project. : “The results you have achieved are indeed very good. Repair is a big aspect of the core application of additive manufacturing, especially for large power station equipment. When the equipment arrives at the site, it can be repaired and strengthened in situ in a small space. That’s a very important feature.”

During the project development process, 5 invention patents, 22 utility model and appearance patents, and 11 software copyrights were obtained.

So far, this project has generated a cumulative economic benefit of more than 786 million yuan after repairing the turbine units of the Three Gorges and Gezhouba Hydropower Stations and has generated economic benefits of more than 349 million yuan for the maintenance of downhole tools in oil and gas fields of oil service companies such as Schlumberger and Zhongman Petroleum. In addition, the results of this project also have extensive technical applications in coal, nuclear power, and other industries, and have significant economic and social benefits.
