“…A confirmation test was taken for validation purposes and to confirm the result. Ghosh et al [7] identified an optimal parametric combination of MIG welding for quality of weld of austenitic stainless steel AISI 316L by adopting Taguchi technique. An orthogonal array, S/N ratio, and ANOVA were employed, the welding characteristics of material were studied, and the welding parameters were optimized.…”

Advanced high strength steels (AHSS) are multiphase steels that contain various concentrations of ferrite, bainite, martensite, and retained austenite phases. The unique physical characteristics of AHSS present some challenges to welding and bonding processes. AHSS have tendency to change microstructure and mechanical properties by any welding process like other steels. Based on the significant applications in various industries, the experimental works are carried out on one of AHSS materials, EN-10149-2 S700MC, with thickness of 2 mm steel sheet metal by MIG welding process parameters such as current, voltage, and welding speed. For all combinations of process parameters, the butt joints are fabricated. The butt joints are inspected through different nondestructive testing for defects detection. All the defect-free joints are characterized through microstructure (at different zones of joint), hardness, and tensile tests. From the obtained mechanical test results, the process parameters are optimized through design of experiment techniques (DoE). The analysis from DoE method is used to identify which parameter is the most significant among all parameters. Confirmatory test is also done by taking the optimal parameters and the result shows that the improvement of the response variables is acceptable and also shows that the method that is used for optimization was valid.

“…[6] Himanshu Garg et al (2019) have reported reviews on the TIG and A-TIG welding processes of Austenite Stainless Steel (ASS) which include numerous recent experimental work and also good mechanical properties. [7] Ghosh et al (2016) experiments were conducted to investigate the effect of nozzle, current, and gas flow rate to plate distance on weld eminence in metal gas arc welding of Austenitic stainless steel AISI 316L. The results calculated are in the form of influence from each parameter, through which best parameters are recognized for the highest tensile strength and good percentage of elongation.…”

Consuming various TIG welding settings, the impact of mechanical properties on the butt joint of 410-Martensitic Stainless Steel Plate is explored. Mechanical properties such as tensile strength and hardness are evaluated on the welded butt junction plates using three levels of 200 A, 220 A and 240 A welding currents and the electrode diameters of 1.5, 2 and 2.5 mm and four factor parameters of inputs. Welding current, wire feed rate, electrode diameter, and gas flow rate are set as input parameters. The optimal input responses of welding current, electrode diameter, wire feed rate, and gas flow rate are employed over the 27 sample specimens based on array L27 Design of Experiment tool. The input parameters 240 A of welding current have improved significantly over the structural changes on martensitic form which is evidenced by their multiple SEM Micrographs, as it can be seen in the Hardness up to maximum of 512 BHN and the Tensile strength of 1090 N/mm 2 outcomes.

“…ough the study using Taguchi methods on weld geometries and mechanical properties has always been reported in literatures [11][12][13][14], it appears that the optimization of FCAW process parameters for the ferrite content in duplex stainless steel using the Taguchi method has hardly been studied. In view of the abovementioned facts, the Taguchi method with L9 orthogonal array and ANOVA is employed to analyze the effect of each weld processing parameter (welding current, welding voltage, welding speed, and torch angle with reference to vertical) for the ferrite content in flux-cored weld metal of 2205 DSS.…”

This study presents the Taguchi design method with L9 orthogonal array which was carried out to optimize the flux-cored arc welding (FCAW) process parameters such as welding current, welding voltage, welding speed, and torch angle with reference to vertical for the ferrite content of duplex stainless steel (DSS, UNS S32205) welds. The analysis of variance (ANOVA) was applied, and a mathematical model was developed to predict the effect of process parameters on the responses. The results indicate that welding current, welding voltage, welding speed, torch angle with reference to vertical, and the interaction of welding voltage and welding speed are the significant model terms connected with the ferrite content. The ferrite content increases with the increase of welding speed and torch angle with reference to vertical, but decreases with the increase of welding current and welding voltage. Through the developed mathematical model, the target of 50% ferrite content in weld metal can be obtained when all the welding parameters are set at the optimum values. Finally, in order to validate experimental results, confirmation tests were implemented at optimum working conditions. Under these conditions, there was good accordance between the predicted and the experimental results for the ferrite content.
