Abstract

A 3-D finite element model of residual stress and distortion in welded structure with square section for angle steel is developed based on thermal-elastic-plastic theory. The residual stress and deformation for welded structure under different conditions are calculated and their distribution characteristics are comparatively analyzed. Results show that, relatively larger stress is generated in and near the weld zone for the welded joint. With an increase in weld length, both equivalent stress and residual distortion increase accordingly, but the effect of weld length on welding residual stress is limited. Under the conditions of 20 mm, 50 mm and 100 mm long welds, the deformations of the three reinforced structures caused by 15000 Pa external load are 4.80mm, 4.79mm and 4.78mm respectively, indicating they have the similar bearing capacity.
