In this paper, multi-layer and multi-pass arc additive manufacturing experiments were carried out on the Q345 substrate using Y309L welding wire. Based MSC. Marc software, a thermal-elastic-plastic finite element method was developed to numerically simulate temperature field, stress deformation during process. The effects of thickness interpass discussed. results indicated that deposition materials at different positions experienced thermal cycles, which might lead non-uniform microstructure...
Based on Marc. MSC software, this paper developed a thermo-elastic-plastic finite element method (FEM) to simulate the welding residual stresses and deformation in low alloy high strength steel joints. The Q345 Steel H-section butt-welded joints were calculated using method. An joint was fabricated measured. simulation experiment, influence of sequence stress distribution investigated. results indicate that has relatively small effect flanges joints, but significant web. Under three...
Local vacuum electron beam welding (LVEBW) breaks through the limit of chamber and can be flexibly proceeded in more working conditions. Using LVEBW to substitute conventional gas metal arc will greatly improve production efficiency. In view severe effect residual stress (WRS) on product safety, WRS induced by two methods should comprehensively evaluated, thus for providing designer engineer with a theoretical basis guidance control thick-plate joint. This paper investigated deformation...
