【Ten Years of Rapid Development in Chemical Processing Equipment】1132–2023: China’s First Nine-Axis Fully Automated Intelligent Welding Robot

Thread Content

Ten years of rapid development in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more interesting. With you here, HaiChuan becomes even better. [Ten years of progress in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhance quality awareness and promote high-quality development. -----------------------------------------On May 6, 2023, Shijian Company held a launch event for the use of nine-axis fully automatic intelligent welding robots, and these robots were put into operation officially. This marks the first time that intelligent welding robots have been used in the history of Sinopec’s engineering construction, filling a gap in this technological area within China’s petrochemical manufacturing and installation industry and enabling a transition in pipeline welding technology from automation to intelligence. Building on a solid foundation of cooperation between Shijian Company and Nanjing University of Science and Technology, and after going through eight stages of technical research and development testing, they successfully developed China’s first 9-axis full-position intelligent welding robot, which was used for the first time in the Yangzi Oil Refining Plant restructuring project. The application of nine-axis welding robots further expands the range of applications for pipeline prefabrication in factories. It enables automatic welding in the deep prefabrication process, shifting traditional pipeline construction from a \"2D\" approach to a \"3D\" one. This represents an further expansion of the use of automatic welding in pipeline prefabrication, and it is a small step forward toward more intelligent applications; it holds significant importance as a transition from \"0\" to \"1\". The successful development of the nine-axis system has enabled the accumulation of technical capabilities in areas such as visual recognition, reverse reconstruction, trajectory planning, software algorithms, and data application – all of which represent the forefront and key directions of the industry. It has laid a solid foundation for subsequent research and development efforts related to robots for welding the arc-shaped seams on equipment enclosures, robots for root welding, as well as the integration of positioners with N-axis robots. It has also provided ideas and directions for advancing mobile welding and automatic welding in the petrochemical engineering industry toward intelligent welding. The technical expertise developed during the research and development process will also contribute to the improvement of the construction methods used in petrochemical projects.
