MECHANICAL PROPERTIES OF WELDED ALUMINUM MAGNESIUM ALLOY PLATES
Abstract
The transverse tensile properties of welds in aluminum-magnesium alloy plates of 5083-H115 and 5456-H321 were obtained for 1-1/4 in. thick plate. The filler metals tested were the aluminum-magnesium alloys 5183, 5556, and 5456, and the aluminum-silicon alloy 4043. The test assemblies were welded by the semi-automatic gas metal-arc (MIG) welding process. The tensile specimens were tested with the weld reinforcement removed. The highest mechanical properties for each base metal alloy were obtained using either 5183 or 5556 filler metal. The base metal/filler metal combination 5456/5556 produced the highest tensile strength of all combinations tested. The highest joint efficiency, however, was obtained with weldments 5083/5183 and 5083/5556. Although yield strengths differed only slightly, the highest values were obtained with 5456/5183 and 5456/5556. Combination 5083/5556 provided the greatest elongation within a three-inch gage length.
