PARAMETRIC OPTIMIZATION OF GMAW WELDING PROCESS

Abstract

The paper presents the Hallmark of Fabrication parameters and their intensive impact of current, voltage, and speed on ultimate tensile strength (UTS) of AISI 1030 mild steel material During Fabrication. A plan of experiments based on Taguchi technique Method has been Carried out. Orthogonal array, signal to noise (S/N) Ratio, Analysis of variance (ANOVA) are employed for studying the welding characteristics of material & to optimize the weld parameters. The result Obtained are the output from each parameter, through which optimal parameters are found out for maximum tensile strength. Observation-welding current and welding speed are major parameters has a deep impact on the tensile strength of welded joint.
