Özet
One of the mainconstruction materials used in armor vehicles is Mil-A 46100 Armor Steel. Theimportance of the material arises from its mechanical properties such ashardness and explosive protection capability. MIG (Metal Inert Gas) welding technique is principallybased on welding metals via electric arc where the arc is continous betweenmetals and welding wire. In case welded metals are steel based materials, O2and CO2 are added in portective gases in order to preventunexpected welding defects. In MIG welding applications, the amount of ferritin the chemical structure of the armor steel may result in some unexpectedaffects due to its decreasing characteristic on ductility and toughness. Thewelding wires used in MIG operations may exibit different fracturecharacteristics; as some specimen show ductile fracture characteristics, therest may show brittle. Charpy Impact Test is one of the effective tests todetermine the impact energy and the fracture times of welded metals. In thisstudy, it is aimed to determine the relations between micro-structural resultsand fracture times of the welded parts of Mil-A 46100 steels via MIGapplications.
