The Effect of Multiple Weld Repairs on the Fatigue Resistance of Welded Aluminum Alloy 5083-0.

Abstract

This work follows that of Lt. G. R. Speight, USCG, on the general microstructural and mechanical property effects of multiple weld repairs in 5083-0 aluminum, and extends the previous study in to the area of fatigue. The essential observation made is that multiple weld repairs do not significantly affect the fatigue resistance of the material. Microstructural changes in the base metal do not alter crack initiation and propagation characteristics, failure being confined to the weld filler material. (Author)
