The effects of multiple weld repairs on the aluminum-magnesium alloy 5083-0 as used in the primary self-supporting containment systems for Liquified Natural Gas Tankships were studied. The changes experienced by the material in microstructure, mechanical properties and stress-corrosion susceptibility as a function of number of weld repairs were carefully characterized and recorded. The results of these findings are discussed from both the metallurgical and the practical engineering standpoint. (Author)
