The application of computer software system in the field of welding

1. computer simulation technology includes simulation of welding thermal process, welding metallurgy process, welding stress and deformation. Welding is a complex process involving arc physics, heat transfer, metallurgy and mechanics. The computer system can be used to determine the best design, process and welding parameters of various structures and materials, once the computer simulation is realized in the welding process. Traditionally, the welding process is always determined by a series of experiments or based on experience to obtain a reliable and economical welding structure. As long as the computer simulation proves the applicability of the numerical method to a certain problem through a small number of verification tests, a large number of screening work can be completed by the computer, and a large number of experiments have been saved. Work, thus greatly saving human, material and time, in the new engineering structure and new materials welding has very important significance. The level of computer simulation technology also determines the scope of automatic welding. In addition, computer simulation is also widely used to analyze the strength and performance of welded structures and joints. 2. database technology and expert system are used in welding process design and selection of process parameters, welding defect diagnosis, welding cost budget, real-time monitoring, welding CAD, welder examination and so on. Database technology has now penetrated into all aspects of the welding field, from raw materials, welding tests, welding process to welding production. The typical database system includes welding process assessment, welding procedure regulation, welder file management, welding material, material composition and performance, weldability, welding CCT map management and welding standard consulting system. These database systems provide favorable conditions for various data and information management in the field of welding. The welding expert system mainly focuses on process planning, defect prediction and diagnosis, computer aided design and so on. In the existing welding expert system, process selection and process planning are the main application fields, and real-time control of welding process is an important development direction. 3. computer aided quality control technology (CAQ) is used for data analysis and real-time monitoring of welding quality. In addition, the application of computer aided design / manufacture (CAD/CAM) in welding process is also increasing, which is mainly used in numerical control cutting, welding structure design and welding robot. 铜焊丝,Copper Welding Rods,铝焊丝,aluminium welding wire,镍焊条,Nickel electrode,药皮焊条,Flux Coated Brazing Welding Rods
