航空专用焊接数据库及专家系统

Welding Database and Expert System for Aviation

焊接数据库及专家系统是焊接数字化体系的重要组成部分。近年来,随着航空制造业向数字化、智能化方向转型步伐的加快,吸引了越来越多的航空企业开展航空专用焊接数据库及专家系统设计与开发方面的工作。目前在航空制造领域建立的焊接数据库,已实现航空材料焊接基础数据、焊接参数数据、焊接性能数据及典型案例数据的有效存储和共享。焊接工艺设计专家系统的应用,可辅助焊接工艺文件自动设计与管理,大大缩短了焊接工艺文件编制周期;焊接缺陷诊断专家系统可根据缺陷特征判断缺陷类型,或根据缺陷类型分析缺陷成因,对控制和预防各类缺陷的产生及控制焊接质量具有重要的实际应用价值;焊接信息管理平台在数据库平台、专家系统平台以及用户权限管理基础上,实现了焊接工艺流程的在线智能化协同办公。结合航空制造业焊接数字化发展进程,在已有焊接数据库及专家系统研究的基础上,把焊接质量预测专家系统和制造业大数据分析挖掘技术运用到航空焊接数据库及专家系统设计中,将成为未来航空焊接专家系统的发展趋势。

Welding database and expert system is an important part of welding digital system. In recent years, with the pace of the transformation of the aviation manufacturing industry to digital, intelligent direction up, attracting more and more aviation enterprises to carry out the work of design and development of aviation dedicated welding database and expert system. Now the welding database established in the field of aeronautical manufacturing has realized the effective storage and sharing of aviation material welding base data, welding parameter data, welding performance data and typical case data. The application of welding process design expert system can assist in the automatic design and management of welding process documents, which greatly reduces the welding process file preparation cycle; The welding defect diagnosis expert system can judge the defect type according to the defect characteristic or analyze the cause of the defect according to the defect type, and has important practical application value to control and prevent the generation of various defects and control the welding quality; On the basis of database platform, expert system platform and user rights management, the welding information management platform realizes the online intelligent and cooperative work of welding process. With the development of welding process of aviation manufacturing, based on the existing welding database and expert system research, the welding quality prediction expert system and manufacturing big data analysis and mining technology applied to the aviation welding database and expert system design will become the future development trend of aviation welding expert system.
