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.
