| Abstract: | The welding process of the common fillet welds along three orthotropic directions for the large-scale metal structure was simulated by finite element method.Selecting the four different welding orders, the distribution of the temperature field in the welding process was analyzed, the residual stress was calculated under the each welding sequence, and the influence of boundary constrains and welded seams on residual stress were discussed. |
