Study on Transient Buckling Behavior of Thin Plate Structures during Welding Process

For the fabrication utilizing welding method, welding distortion is always one of most complicated problems on welded structure. Furthermore, for the thin plate welded structure, the buckling type distortion is the most prevalent mode of welding distortion compared with other distortion modes. Considering the large deformation theory, the buckling type distortion of welded structure during and after the welding is investigated. In this study, the transient buckling behavior during the welding is studied by means of Thermal Elastic Plastic FE analysis. In 1953, Masubuchi
