Effect of Process Parameters on Bead Width of 202 Grade Stainless Steel Gas Tungsten Arc Welded Plates Using Response Surface Methodology

摘要

Welding quality can be accomplished by meeting quality prerequisites, for example, bead geometry by detecting either directly or indirectly the different procedure parameters engaged with the procedure. Lacking weld bead measurements may add to the disappointment of a welded structure. This paper presents an improvement of a scientific model for foreseeing bead width for gas tungsten arc welding of 202-grade stainless steel plates. This model depends on the connection between procedure parameters and bead width and can be utilized to foresee the impact of procedure parameters on bead width. To assemble the required information for demonstrating, real tests were done dependent on a central composite rotatable plan with 31 test runs. The procedure factors considered here incorporate welding current (I), welding speed (V), gas flow rate (Q) and welding gun angle (θ). The sufficiency of the model was tried utilizing ANOVA procedure. The outcomes demonstrate that the proposed model can foresee bead width with sensible precision. Primary and cooperation impacts of the control factors are exhibited in a graphical structure that helps in choosing rapidly the procedure parameters to accomplish the ideal outcomes.
