Nowadays most of the automobiles aerospace and fabrication industries were started using of aluminium alloys for making the product. This is due to the properties given by the aluminium alloys are more efficient than the other metals. That might be include high tensile strength, sufficient hardness value and very less formation of defects in the welded zone and it is very low cost while comparing the other metals. For investing the mechanical properties of AA6082, the two different fillers and grove angles were taken. That they are ER5556 and ER4043 and groove angles are 45° and 60°. The aluminium plates were welded by TIG welding method which provides more joint efficiency of aluminium metals. After the welding the weld plates were taken into various mechanical and microstructure evaluation. The specimen welded with ER5556 and groove angle of 45° provides more tensile strength and sufficient hardness in the weld joint. In the microstructure examination, the weld joints have uniform distribution of aluminium silicon. The specimen welded with ER5556 and groove angle of 45° an 60° have very less defects which is easily eliminated during welding.
