Analysis Of Mechanical Properties On Friction Stir Welded Aluminium Alloy (AA6063) Plate
Friction stir welding (FSW) is a solid state joining process that uses friction generated by a rotating cylindrical tool which produces heat and plasticize metal on either side of a joint, creating a solid functional weld. Friction-generated heat is more effective at reorganizing the microstructure of metals and metal alloys than other forms of fusion welding. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace Aluminium alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a decade. A comparison is made on Fusion welding (metal inert gas arc welding) and frictional stir welding through various mechanical testing method. They were tested for mechanical properties such as tensile strength and Rockwell hardness respectively. It was found that the mechanical properties of the friction stir welded Aluminium alloy plate were superior than the MIG arc welded Aluminium alloy plate.
