simulation and analysis of vtype weld joint welding process based on 3d model

ABAQUS software, using 3D models, V-shaped seam welding process was simulated which was commonly used in pressure vessels and tower equipment. Each channel of welding can be calculated and give the temperature distribution and stress distribution after welding. At the same time, the simulation welding process takes into account the cooling after welding. After the computer simulation, the stress distribution and strain energy curve of overall structure also were also given.
