Abstract
Research on friction stir welding temperature field, welding heat transfer, thermal cycling process and weld nugget formation was important for welding structure reliability and safety. At present, the domestic and foreign studies about FSW mainly concentrated in the welding process, welding materials, microstructure and mechanical properties of joint of friction stir head mechanism. The results of finite element calculated in this paper, the data in the file storage format was chose for research, the design data is read from the algorithm and realizes the extraction of different types of data. This paper uses the element local stress polishing and method for smoothing, the Gauss integral point welding stress numerical conversion data, laid the foundation for the realization of stress field visualization. In order to realize the data sharing in different formats, the data in a uniform format for the re-storage, analysis and processing was carried out.
