Abstract |
|
Friction Stir Welding (FSW) is a solid state joining process that is most widely used for joining of aluminium alloys due to low cost. In the present work, dissimilar aluminium alloys AA5083 and AA6082 are joined by Friction Stir Welding. Both the alloys are used in shipbuilding, automotive and construction industries. The Parameters like Tool rotational speed, Travel speed and Tool tilt angle are kept constant, whereas Tool pin is set to be offset for 1mm in both advancing side and retreating side on dissimilar aluminium alloys. The effect of Tool pin offset on the weld properties of chosen dissimilar aluminum alloys are studied. The welds are characterized by hardness testing, transverse tensile testing, macro examination & microstructural observation. The results showed that the Tool offset in the advancing side of AA6082 has better weld properties. |
