Friction Stir Welding of Aluminum Alloy and Development of ANN Model

Now-a-days industries are concentrating on those metals, who has higher strength to weight ratio. Thus, many industries such as aviation factories, marine industries, auto industries, packaging industries, etc. are replacing steel structure into aluminum alloy structure. Aluminum alloy has good strength in respect to weight compare to steel. In addition, aluminum alloy possesses outstanding properties such as good corrosion resistance, good conductivity of electricity and heat, good reflectivity of light, non-toxic alloy, recyclable, etc. During the application of aluminum alloys in industries, there is need to join them through welding. But the welding of aluminum alloy is very difficult through conventional welding techniques. It faces so many problems such as cracks, formation of oxide at weld region, reduce strength of joint, large HAZ area, incomplete penetration, solid inclusion, spatters, etc. Other joining processes like joining through nut & bolt, snap joint, mechanical riveting increase the weight of product, which is not acceptable. So, current study focusses on friction stir welding of 6082 - T6 aluminum alloy.
