A Review on Friction Stir Welding of Aluminum Alloy (7075)

Abstract

Friction stir welding is a solid state joining process and is extensively used for aluminium alloys. In a given work it was analyzed that how the tensile strength as well as microstructural behavior of AA7075 varies if the process parameter like axial pressure force, welding traverse speed and rpm of the FSW tool varies to butt weld of two pieces having length 100mm, width 50mm and thickness 6mm have been used. It was preferred friction stir welding process to obtain the particular result over traditional welding process because of no melt of piece, no toxic fumes and harmful radiation which is suitable for environment so FSW is eco-friendly welding process. It can be widely used in aircraft, marine, automotive as well as railways industry because of eco-friendly in nature.
