Friction Stir Welded Joints using Grey Relational Analysis: A Review
Keywords:
Friction Stir Welding, Aluminum Alloy, Pin profile, TensileAbstract
This paper investigates the effect of the tool pin profile and friction stir welding parameters on the microstructure and mechanical properties of the 6061 aluminum alloy welded joints prepared by friction stir welding. It has been found that a fine grain microstructure obtained by hexagonal pin profile. But using a square pin profile produced a higher strength welded joints. FSW process offers a potential advantage in manufacturing industries to eliminate mechanical fastening such as riveted or bolted joints. Incorporation of light aluminum alloy coupled with steel by the FSW process as sub-frame component in auto industries also yields a milestone in the weight reduction capability of this process. There is no melting involved in FSW process, hence this solid state joining technique offers some specific advantages over fusion weld by preserving material properties in the joint closest to that of base materials.
