Abstract
Joining of dissimilar aluminum alloys are widely used in automobile, aerospace and shipbuilding industries. Friction Stir Welding (FSW) has been established as one of the most promising processes to defects free joining of aluminum alloys. The aim of present work is to compare the predicted results of FS welded joint through Artificial Neural Network (ANN) modeling and regression modeling. Three responses tensile strength, average microhardness at weld nugget zone (WNZ) and average grain size at WNZ have been selected. The predicted values by ANN modeling and regression modeling of TS, MH and GS values have been found close to the experimental values. The overall average percentage prediction error of ANN model is small as compared to regression model.
