On April 28, the first pass rate of welding ray inspection of the steel lining cylinder of the containment shell of the reactor building of Tianwan Nuclear Power Unit 7 was 100. This is another successful application of the laser intelligent tracking MAG welding technology independently developed by my country after the implementation of the Hualong No. 1 nuclear power project. So far, this technology has achieved stable welding of more than 3000 meters in domestic nuclear power construction, it marks the successful realization of autonomy and industrialization of another technology in the key core construction of nuclear power in China, and provides a strong guarantee for the high-quality development of China's nuclear industry and the "going out" of nuclear power.
According to the structural characteristics and construction requirements of the containment steel lining of nuclear power plant, CNNC Huaxing and Tsinghua University jointly formed a scientific and technological team to independently develop a laser intelligent tracking control system, MAG welding walking robot and single-sided welding double-sided forming process database, breaking through the technical difficulties of multi-layer multi-channel intelligent tracking welding, having completely independent intellectual property rights and reaching the international initiative.
Compared with the traditional construction process, this process will effectively improve the automatic operation mode and digital management level, change the state of full labor and high-intensity labor of the original process, and increase the comprehensive efficiency by 3 times. It is of great significance to improve the intelligent construction level of nuclear power in China. It will completely change the traditional construction mode, lead the trend of intelligent construction of nuclear power, and open a new chapter of "intelligent construction" of nuclear power.
Since the 13th Five-Year Plan, CNNC has insisted on independent innovation and actively carried out independent development of automatic welding equipment for nuclear power plants. It has successfully developed more than 10 series of welding and testing equipment such as narrow gap TIG welding robot, laser intelligent tracking MAG automatic welding technology, steel lining automatic welding equipment, intelligent low-radiation ray testing equipment and so on, and independently developed a supporting software system, basically covering all components of nuclear power equipment installation, forming a complete set of automatic welding technology for nuclear power plant nuclear island equipment installation, some of which fill the gap of efficient intelligent welding in the domestic nuclear power industry, reaching the domestic first and international advanced level, indicating that the country has the ability to independently develop high-precision nuclear power welding equipment.
