Prediction of Friction Stir Welding Characteristic Using Neural Network

An artificial neural network (ann) model was developed for the analysis and simulation of the correlation between the friction stir welding (fsw) parameters of aluminum (al) plates and mechanical properties. the input parameters of the model consist of weld speed (ws) and tool rotation speed (rs). the outputs of the ann model include property parameters namely: tensile strength, yield strength and elongation. good performance of the ann model was achieved. the model can be used to calculate mechanical properties of welded al plates as functions of weld speed and rs. the combined influence of weld speed and rs on the mechanical properties of welded al plates was simulated. simulated annealing technique was used to prevent the network from getting stuck in local minima. a comparison was made between measured and calculated data. the calculated results were in good agreement with measured data.
