| With the development of brazing technology, considerable of brazing data has been amassed in research and engineering fields, summarizing the brazing data and management will further promote the development of brazing technology. Compared to traditional development of process, through combining with expert system information of brazing process is used efficiently, and the process development assisted with expert system reduces the number of experiments, saves development cost, and shortens the development cycle. Meanwhile, during the development of brazing technology, not only can stimulating residual stress field of brazing joint by finite element method effectively predict the location of crack occurrence, but also evaluate and improve brazing technology in a targeted way finally. In addition, in terms of performance evaluation of joint service process, finite element method associating with relevant experiments is used to simulate the stress state, which can simulate the stress state and deformation process of joint under real working conditions in a more practical way. Finally, guidance is proposed for the development of brazing technology. |
