Abstract
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 modelling and high performance computational hardware. It provides users with easy access to advanced modelling tools over the internet to quickly explore various welding scenarios. This paper reveals the underlying mathematical equations implemented in E-Weld Predictor and discusses several applications of E-Weld Predictor. One application is to understand the effect of heat input on the resulting microstructure, residual stresses and distortion for a U-groove X-65 steel butt joint. Results show that a larger heat input is likely to result in higher heat build-up, larger residual stresses and larger distortion. Another application is to calculate the cooling rates for a narrow groove X-100 steel weld. The results show that increase of preheating temperature reduces the cooling rate. It is hoped that by providing easy-to-use and accessible advanced weld models, the usage of the computational models will be increased by welding and design engineers in the industrial companies.
