Development of Online Weld Modeling Tool for Automotive Applications - (PPT)

摘要

On-line software tool, E-Weld Predictor, has been developed to predict temperature, microstructure, stress, and distortion for arc welding processes by combining the power of numerical weld modeling and high performance computational hardware. It provides users with easy access to advanced modeling tools over the Internet to quickly explore various welding scenarios. This paper introduces the software structure, the theory, the implementation, and the application of E-Weld Predictor for automotive application. The new development of predicting weld sizes, microstructure, weld residual stress, and distortion for arc welding processes will provide benefit to automotive industries. It will help design engineers to better design welded structures and help manufacturing engineers to qualify and optimize welding processes.
