Bhabani Sora (EDT) Experimental Investigation and Parametric Optimization of Friction Stir Welding on Aluminium Alloy 6061-T6

Annotation

Friction Stir Welding (FSW) is a green solid-state joining process which can easily join alloys that are generally difficult to weld by conventional fusion welding. This process uses a non-consumable spinning tool bit. The relative motion between the tool and the work piece produces heat, which joins the material of two edges by plastic atomic diffusion. This joining technique is energy efficient, environmentally friendly and versatile. An attempt has been made to review the research papers on experimental work carried out in the field of friction stir welding and its impact on microstructure, fracture surface, and thermal and mechanical properties of welded joints. Also, Tungsten Inert Gas (TIG) and Metal Inert Gas (MIG) welding have been carried out to compare their mechanical and micro-structural properties with FSW.
