Parametric optimization of dissimilar delding of AISI 409 ferritic stainless steel to AISI 316L austenitic stainless steel by using PCA method
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 75, Issue 1
Abstract
Purpose: Taguchi design has been adopted in order to identify optimal parametriccombination for desired quality of weld. Microscopy was conducted to study the effectof welding input process parameters (welding current, gas flow rate and nozzle to platedistance) on MIG weld microstructures of AISI 409 ferritic stainless steel and AISI 316Laustenitic stainless steel.Design/methodology/approach: A plan of experiments based on Taguchi technique hasbeen used.Findings: The present work is planned to investigate some perspectives of GMAW dissimilarjoints between AISI 409, a ferritic stainless steel and AISI 316L a austenitic stainless steel.Research limitations/implications: The main objective of the present study wasto apply the Taguchi method to establish the optimal set of control parameters for thewelding. The Taguchi method is employed to determine the optimal combination of designparameters, including: current, gas flow rate and nozzle to plate distance. the observeddata have been interpreted, discussed and analyzed by considering yield strength , ultimatetensile strength and percentage of elongation combined with use of principal componentanalyses (pca) method.Practical implications: Dissimilar welding is the joining between two different materialsby any welding process. Dissimilar weld has made considerable attention in many fields,such as in ship industries and nuclear power plant.Originality/value: The result computed is in form of contribution from each parameter,through which optimal parameters are identified for maximum tensile strength andpercentage elongation. This paper presents new results of optimization using principalcomponent analyses.
