MEASURING LUMINANCE AND SUN DEPRESSION ANGLE OF DAWN

In this study, the weld ability of Aluminium Alloys 5083,6061,7075 and Magnesium AZ31 was investigated using Friction Welding. Magnesium AZ31 is the base alloy used and other Aluminium alloys were welded with Magnesium Alloy. These Alloys are welded by changing the parameters. Parameters which were used are Spindle Speed , Friction Pressure , Friction time, Forging Pressure and Forging time. After Friction Welding , Interface regions of the welded specimen were examined by Scanning Electron Microscope (SEM) to determine the Microstructure changes. Micro hardness and Tensile Tests are conducted to determine the Mechanical properties of the welded specimens. The Experimental results indicate that the combination of Magnesium AZ31 alloy and Aluminium Alloys using Friction Welding Technique for achieving a weld with specific strength.
