Optimization of Process Parameters of GMAW using TLBO Technique

In this paper, the optimization of bead geometry using TLBO technique is presented which includes the effect of welding parameters like wire feed rate, welding voltage, welding speed and gas flow rate on bead geometry parameters of AISI 430 grade stainless steel material during welding. A plan of A plan of experiments based on TLBO technique has been used to acquire the data. Central composite Design Matrix and analysis of variance (ANOVA) are employed to investigate the bead geometry parameters of AISI 430 grade SS material & optimize the bead geometry parameters. Finally the conformations tests have been carried out to compare the predicated values with the experimental values confirm its effectiveness in the analysis of penetration.
