Experimental investigations of mechanical behavior of friction stir welding on aluminium alloy 6063

The conventional welding of Aluminum alloy 6063 faced many problems related porosity in the fusion zone and loss in Mechanical properties. To overcome these difficulties the Similar Aluminum alloy 6063 were welded by using friction stir welding process and the mechanical characteristics and
microstructure were investigated by varying the Tool rotation speed, welding speed and axial force. icrostructure of different zones were analyzed and observed by electron optical microscope. The tensile properties and hardness is evaluated for AA6083 Welded joints. It is found that welding speed 72 mm/ min, Tool rotation speed 1000 rpm, axial force 14.5 KN Produces better tensile strength. Welded zones
categorizes three different zones are interfacial zone, Nugget zone and parent metal were investigated.
