Simulation and Stress Analysis of U-Shaped Seam Welding Process Based on ABAQUS

Abstract:

At present, there is large-scale trend for chemical containers and reaction tower in the industry. In the large-scale equipment, U-shaped weld structure are widely used for splice weld of container wall. In this paper, by ABAQUS software, using plane models, U-shaped seam welding process was simulated which was commonly used in pressure vessels and tower equipment. For welding material part, the calculation use of "dead-actived elements" technique, and the weld material part was divided into finer grid. The calculation model of the plane model was created using CATIA software, the software plug-in software was used to transform the model to directly read the ABAQUS software model. Calculation can be given to each welding temperature distribution and stress distribution. At the same time, the welding process to consider the cooling after welding. Computer simulation gave the overall structure of the stress distribution and strain energy curve.
