The Characterization of Welded AA 5005 Alloy with AA 5356 Filler Metals According to Slow Welding Rate Using by MIG Welding Technique

Abstract

In the present study, AA 5005 cold rolled plate was used for welding application with AA 5356 filler materials using MIG welding process. Slow (780 mm/min) welding rate was applied for weld joint of the plate. After the welding operation, NDT tests (Visual Test, Liquid Penetrant Test, Radiography Test) and X ray Diffraction analyzes were applied to the welded plates for proving the weld quality and determination of the phases in the weld beat during the solidification of the weld pool. Then, microstructural color metallography technique was used for the investigations of grain size distribution of the weld joint and heat affected zone and base metal. Vickers microhardness tests applied on the cross-section of the weld joint together with HAZ and base metal. In addition these, tensile tests were realized for the determination of the mechanical properties of the welded cold worked AA 5005 alloy with AA5356.
