Zusammenfassung:Aluminium-magnesium Alloy AA5083 is used widely as a building and tooling material in aerospace, automobile, and marine industries. This Work shows the comparison of AA5083 (armor grade) - 6mm thickness plate weldments mechanical properties on TIG Welding and FSW processes. Welding of metals is based upon the input parameters as it has an important role of finalizing the weldment and the tool used for welding is H13 Tool Steel as the tool has less deformation due to high chromium content. Generally, the welding processes are aimed at achieving a welding joint with superior mechanical properties with minimum deformation. The tensile strength of the weldments is found by testing in the Ultimate Tensile Strength (UTM) machine. The hardness test is performed by Vickers Hardness tester to characterize the welded area. Macro Vickers Hardness is performed in the welded area of the workpiece to finalize mechanical properties in different heat-affected zones of FSW welded workpiece to analyze and find the efficient input parameter of FSW. The efficient input parameter for TIG welding is identified and a comparative study is made and the result proves that FSW welding is a better welding technique.
