Comparison is made of relative merits of spot-welded and riveted aluminum-alloy structural elements. Spot welds were tested for static shear strength, shear fatigue, and direct tension-compression fatigue. Spot-welded construction can be made to equal riveted construction in resistance to static and impact loadings. In resistance to fatigue, spot welds are inferior unless welds can be produced which are more sound and free from cracks than those examined.
