In this study, the effects of various welding parameters on bead geometry and bead hardness in IS 2062 E250 B Mild steel having dimensions 120 mm x 80 mm x 6mm, welded by robotic gas metal arc welding were investigated. The welding current, arc voltage and welding speed and torch angle (travelling angle) chosen as variable parameters. Bead hardness, bead width and reinforcement was measured for each specimen after the welding operations and the effects of these parameters on bead hardness and bead geometry were researched. A plan of experiments based on Taguchi technique has been used to acquire the data. The experiments were conducted based on a four-factor, three-level. An Orthogonal array, signal to noise (S/N) ratio are employed to investigate for maximize the bead hardness and minimize the bead width & reinforcement of IS 2062 E250 B Mild steel material. Finally the conformations tests have been carried out to compare the predicated values with the experimental values confirm its effectiveness in the analysis of welding parameter.
