Abstract

Nowadays structural application demands two important features in the fabrication and manufacturing of the materials. They are reduction of the weight and as well as cost. Aluminium (Al) alloys are the best choice for controlling these two features and perfectly replacing steel in many industrial applications. The Friction Stir Welding (FSW) technique is a good, powerful, and worthwhile method and one of the leading and appropriate joining techniques for Al alloys. The solid phase nature of this process controls many defects especially melt-related defects. Primarily, it is applied for low melting materials although the applications are extended for high melting point materials including steels and composites. The present study describes the tensile, hardness, and impact characteristics of Friction Stir (FS) welded butt joints of similar aluminium alloy groups of AA6351 with AA6351, AA5083 with AA5083 alloy, and dissimilar aluminium alloy group of Al AA6351 with Al AA5083.
