General note The in-progress research effort is to optimize the gas metal arc welding parameters on the<br/>impact strength, flexural strength, and hardness of the fused generated part of SS316L using<br/>the Taguchi-based grey relational technique. Due to its low cost and great efficiency,<br/>experiments have been done in conjunction with fused deposition modeling (FDM) as a viable<br/>metal additive manufacturing technology. To create the laminated component, the metal AISI<br/>316L wire is heated, extruded, and other techniques are used. However, it is commonly<br/>assumed that FDMS jobs have scanty and anisotropic tensile properties, which are always<br/>attributed to the weak inter-layer amalgamation. The current study seeks to improve the tensile<br/>characteristics and gain a better understanding of the anisotropic fracture behavior of 316L<br/>stainless steel fabricated via FDMS. It is possible to perceive the surface defect of weld joints<br/>made of 316L austenitic stainless steel. MIG welding parameters, gap between base metal and<br/>nozzle, voltage, and arc current were altered up to three stages, and their special effects on<br/>tensile strength, hardness, tensile strength, surface roughness, and microstructure were<br/>determined. Some parameters are controllable by the machinist, and these parameters<br/>encompass a shortest or indirect collision where the microstructure and mechanical attributes<br/>of the weld meet. In this study, three MIG welding attributes, arc current, voltage, and gap<br/>between base metal and nozzle, were changed up and down to three levels, and their special<br/>effects on surface roughness, hardness, tensile strength, and microstructure were investigated.<br/>Experiments were passed out on a 3 mm thick plate of austenitic stainless steel AISI 316L<br/>exploring MIG welding apparatus and were premeditated according to Taguchi L9 orthogonal<br/>array (OA). Experimentation was run out two times using two unlike filler materials, ER 316L<br/>and ER 309L. For each solo response, input parameters were determined, and the most<br/>favorable parameters were acquired. Additionally, the signal-to-noise (S/N) ratio and analysis<br/>of variance (ANOVA were used to assess the data. The MINI Tab software was used to<br/>optimize the results. It was found that each input parameter influences the reaction. The<br/>adjustment of filler material had manipulated the response, i.e., mechanical attributes and<br/>surface roughness. The microstructure assessment shows that dendritic lathy δ-ferrite<br/>structure,” fine and coarse δ-ferrite structure are nearby in the weld region of various jobs.
