Multi Response Objective Optimization of Friction Stir Welding Parameters of Dissimilar Metals of AA 6061 Aluminum and IS319 Brass Joining Through Taguchi’s Method
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 1
Abstract
Dissimilar metals welding can be used where, combination of properties light weight and high strength was interested. Aluminium and Copper and its alloys are light metals have special properties, such as high electrical and thermal conductivities with excellent corrosion resistance. They can be used with combination in aerospace and automobiles industries. To join these dissimilar metals, a solid state friction welding is preferred over a conventional fusion welding, because of their typical metallurgical properties. In this present work, friction stir welding was performed to join two dissimilar Metals of AA6061Aluminum and IS319 Brass. A statistical method design of experiments through Taguchi approach was applied. The welding process parameters such as tool rotational speed, tool feed rate and tool pin geometry are optimized by considering the response parameter such as welding strength (UTS) and ductility (% of elongation). A grey relation grade is carried out with ANOVA to evaluate the significant contribution of process parameters. Optimal condition of parameters for sound welding was identified through this approach.
