Abstract
In this work, an attempt is made to identify the optimized parameter combination for improved creep and corrosion properties of AA5083-H111 alloy weldments processed by Spin-Arc gas metal arc welding (SA-GMAW) process. For this, the Artificial Neural Network (ANN) coupled with Genetic Algorithm (GA) was used as a statistical tool. Experiments were conducted by considering the input parameters namely welding current, filler spinning speed and filler spin diameter. The weld quality was assessed by measuring microhardness, corrosion resistance and steady-state creep rate. Initially, ANN was used to establish the relationship between input and output process variables. Different learning algorithms such as quick propagation (QP), back batch propagation (BBP) and incremental batch propagation (IBP) were used for predicting the output parameters. Prediction accuracy of the different learning algorithms was compared, and the best algorithm was used for the GA optimization technique. The optimum parameters were found to be 134 A of welding current, 1050 rpm of filler spinning speed and 1 mm of filler spin diameter. Among the input parameters, the filler spinning speed was identified as the most influential factor (40.11%) that effected the formation and distribution of second phase particles through which improved corrosion and creep properties were achieved.中文翻译:
