In this study, the special weld grooves was created on 7039 Al-Zn armor plate with different thickness of 12.7 and 38 mm and they were welded with MIG welding technique via multiple pass. After that, the ballistic and mechanical properties of these plates were examined. V50 ballistic limit values of the base metal, the heat affected zone and the weld metal of the welded plate of 38 mm thickness were determined by shooting with laboratory bullets of 12.7 mm. 12.7 mm thickness welded plates were used for determining the mechanical properties. It is observed that the ballistic and mechanical properties of the welded samples decrease. Moreover the highest V50 ballistic limit value was obtained from the base metal whereas the lowest V50 ballistic limit value was obtained from the welded metal. [ABSTRACT FROM AUTHOR]
