To design a suitable welding procedure instruction, it’s necessary for welding engineers to have solid professional knowledge and rich experience. Consulting a large number of welding standards and welding process documents is also unavoidably which implies heavy workload and complicated operations. With the development of various artificial intelligence technologies, intelligent process planning technology has been introduced the field of welding, and experts have been replaced to carry out welding process design work gradually. This paper introduces the development status of intelligent design of welding process at home and abroad and the common intelligent design technical means. The domestic development path of intelligent welding process design is mainly introduced. After decades of development, our welding process intelligent design system has independent intellectual property rights. Finally, the development trend is prospected as well. 焊接工艺设计 人工智能 数据库 专家系统 welding process design artificial intelligence database expert system TG44 2022-03-08 9 50
