| Abstract: | In this paper, the basic principles and influencing factors in the welding groove selection and design of pressure vessels are analyzed. Based on the subjective Bayes method, a total probabilistic reasoning model for approximate reasoning is presented. The welding base metal database, welding materials database and welding technology database are built, and the computer aided reasoning system of groove selection and design is realized. The practicality and rationality of the reasoning system are verified through a concrete example. The system can be used to computer aided selecting and designing of welding groove during pressure vessel manufacture. |
