Arc Welding Process Expert System For Low-carbon & Low Alloy Steel

Welding procedure ES (expert system) is a powerful tool to help technician design WPS (welding process specification). Designing WPS is a primary technical preparation work in all kinds of welding structures manufacturing. Improving the efficiency of designing WPS by building welding ES is important for the factory to economize cost,shorten technical preparation period and reduce labor intensity. In addition,it will play an important role in improving the modern management level of the factory.Welding ES belongs to applications of technical management. As a kind of tech-storage,a part of the whole ES has been completed in this system which involves the arc welding process of low carbon & low alloy steel used in railway,bridges and other steel structures.The system can simulate welding expert to help technicians to complete procedure parameter design,set down WPS and save them. Besides the mechanical property and chemical composition of low carbon & low alloy steel,the weldabiliry and the defect forming analysis of them have been given in the system. Furthermore,the estimation of welding cost and welding procedure files management can be accomplished.For meeting the need of network and integration for corporation,the system established as a simple C/S net model,which can support the communication of data.The system adopts the adding exploiting model,based on which user can gradually expand the system. The data of repository departed from inferrer will become share database managed with database management system. Users can expand the system for their needs. Multi-model of the inferrer is convenient for users to debug and manage. Improving the opening of the system,on-line help users master the principle in short time.
