A COMPREHENSIVE REVIEW OF NOVELTY OF FRICTION STIR WELDING OF ALUMINIUM – MAGNESIUM ALLOYS FOR ADVANCED ENGINEERING APPLICATIONS

Ramesha K, Santhosh N, Raman Bedi, Sudersanan P.D

Abstract


Aluminum and magnesium based alloys are majorly finding their applications in industries like automobile, aerospace and sports applications. The joining of these dissimilar alloys is very difficult by using traditional fusion welding technique inherently because of the “brittle Inter Metallic Compounds (IMC)” like Mg2Al3 and Mg17Al12. In order to enhance the joint strength, the formation of inter metallic compounds due to friction stir welding has to be characterized at the first. The friction stir welding is one of the latest solid state techniques used to join the dissimilar alloys of magnesium and aluminum. “In the current paper some important welding parameters and their effects on weld quality are discussed along with the mechanical properties of the weld joint”. Thus the main aim of this paper is to get an overview of recent research progress in “welding of dissimilar aluminum alloys and magnesium alloys to give a platform for future research based on the extensive review of the literature”.
