Abstract
Friction welding is a solid state joining process in which the quality of welded joint is influenced by the input parameter setting The objective of the present study is to conduct experimental investigation of the bond strength and hardness of the friction welded joints involving AA 6061 and AA 6351 alloys by conducting experiments designed by Taguchi’s L9 orthogonal matrix array A systematic approach becomes essential to find the optimal setting of friction welding parameters Hence a new approach named greyprincipal component analysis GPCA is presented in which the principal component analysis PCA is used to generate weights for the grey relational coefficients obtained in the grey relational analysis GRA The results of the confirmation experiment conducted with the optimal setting predicted by the GPCA have shown improvements in the performance characteristics Hence GPCA can be used for experimental welding optimizationR Adalarasan received his ME degree in Production Engineering from the Faculty of Engineering and Technology Annamalai University in 2000 and currently works as an Associate Professor in the Department of Mechanical Engineering at Saveetha Engineering College Chennai India He has authored more than 10 papers published in international journals and at international conferences His research interests include welding processes MMCs optimization and metaheuristicsM Santhanakumar received his ME degree in Industrial Engineering from the College of Engineering Anna University in 2005 and currently works as an Assistant Professor in the Department of Mechanical Engineering at Saveetha Engineering College Chennai India He has presented more than 5 papers in international conferences His general research interests include Abrasive machining processes multi response optimization and operations researchA Shanmuga Sundaram is a citizen of India born in Vellore Vellore District Tamilnadu on June 26 1978 He received his Bachelor’s degree in Mechanical Engineering with First Class in the year 1999 from the BharathiarUniversityTamilnadu He obtained his Master’s degree with First Class in the field of Thermal Engineering from the University of Madras Tamilnadu in the year 2000 He received his PhD at Anna University Chennai in 2009 He is currently working as Professor at Sree Sastha Institute of Engineering and Technology Chennai India His research interests are thermal management of electronics thermal energy storage and heat transfer
