The welding parameters such as current, voltage, arc length, wire feed rates, wire stick-out distance etc will influence on the deposited weld bead geometry. Statistical design of experiments using orthogonal arrays and signal-to-noise (S/N) ratios are performed to constitute the core of the robust design procedure. Taguchi Methodology was employed with minimum number of trails as compared with classical statistical experiments. This study systematically revels the complex cause-effect relationships between design parameters and performance. Thus an optimized weld bead width and heights are formulated for the exterior contour weld path deposition and for the interior layer metal path deposition respectively.
