Abstract

Aluminum–Magnesium alloys are widely used in the construction of transportation industries bodies of structures in automobile, railways, and marine industries. The fusion welding techniques such as metal inert gas welding and tungsten inert gas welding are widely used in the fabrication sectors. During fusion welding, the important alloying elements, which have been added for improvement in strength, will be subjected to evaporation. The loss of alloying elements in the welded joints is compensated by adding suitable welding filler rods during the welding processes. Friction stir welding is a recently introduced solid-state welding technique, which eliminates most of the solidification defects found in fusion welding techniques. In friction stir welding process, the tool pin profile plays an important role in mixing the materials to be joined. Selection of suitable pin profile will reduce the defects to be formed in the welded joints and improve its welded joint efficiency. The friction stir welded joints of AA5052-H32 and AA6061-T6 were subjected to mechanical and metallurgical characterization, and the results were analyzed. In this research, an attempt has been made to study the feasibility of joining the dissimilar combination by using cylindrical pin profile.
