| Abstract | This study is aimed at obtaining a relationship between the values defining bead geometry and the welding parameters and also to select optimum welding parameters. For this reason, an experimental study has been realized. The welding parameters such as the arc current, stick out, arc voltage, and welding speed which have the most effect factors on bead geometry are considered, and the other parameters are held as constant. By considering Taguchi’s L27, 3 level 4 parameter orthogonal array design of experiments, twenty seven samples analyzed, and the bead reinforcement values of the weld bead are measured. Then, the relationship between the welding parameters is modeled by using multiple regression analysis. Each model is checked for its adequacy by using ANOVA. The proposed model is compared with the experiment values, and it has positive correlation with maximum of 14.23% and the minimum of 2.06% error. The results were confirmed by further experiments. |
