Abstract

An experimental investigation has been meted out on Hardness distribution, tensile properties and microstructure of weld, butt joints of 6061 metallic element alloy. Two completely different fastening methods are considered: Associate in nursing innovative solidstate fastening method referred to as friction stir fastening (FSW) process and Friction Stir spot fastening. The shaping pressure and mix of the plasticized material lead to the formation of a solid bond region in friction stir spot fastening (FSSW) Instead, in FSW joint, lower temperatures area unit concerned within the method because of severe plastic deformation induced by the tool motion and lower decay of mechanical properties. Within the hunk zone, a small recovery of hardness is ascertained because of recrystallization of terribly fine grain structure. Therefore, from industrial views, FSW method is incredibly competitive assist saves energy, has higher lastingness and prevents the joints from fusion connected defects. FSW is one of the important welding processes that can be adopted for welding of Aluminum alloys with excellent mechanical properties.
