In this paper, ANSYS finite element analysis software was adopted in the numerical simulation on temperature field of FCB three wires submerged arc welding. Considering the deflection of welding wire, the heat source model of three wires submerged arc welding was established by overlaying the double ellipsoidal heat source. Through adopting different meshing ways, we saved time in analog computation and saved computer resource occupation, and with the application of parametric design language of ANSYS, we realized the computation of heat source flux density as well as the moving heat source load of three wires submerged arc welding. By repeatedly adjusting the shape parameter of double ellipsoidal heat source model, the analog computation results were eventually matched with the results obtained by practical welding process, and thus the optimal simulation scheme was determined. |
