Abstract | Automatic MIG was adopted to weld Inconel 625 alloy on 20 G Membrane Water-wall, which can improve the capacities of high temperature corrosion resistance and wear resistance. To study the influence of Membrane Water-wall surface welding sequences on residual stress and residual deformation, this paper utilized finite element software ABAQUS and segmented moving heat source model to simulate the sequence welding, balanced welding from the middle to sides, balanced welding from sides to the middle, balanced skip welding from middle to sides and balanced skip welding from sides to the middle and studied their residual stresses and deformations. The simulation results indicated that there was a great influence of welding sequences on the residual stress and deformation. The optimal welding sequence was balanced skip welding from middle to sides and balanced skip welding from sides to the middle, which could change the stress distribution, decrease the welding residual stress by 17%, realize the even deformation of the whole welding section and decrease the bending deformation by 50%. © (2014) Trans Tech Publications, Switzerland. |
