ESDU 92017 presents the results extracted from the literature of nearly 850 constant amplitude loading fatigue tests. Joints were: load-carrying and non load-carrying transverse cruciform, load-carrying and non load-carrying transverse and longitudinal cover plate, single- and double-fillet lap under axial loading. Data are included on fillet welded attachments under axial loading and tee fillet welded joints under axial or bending loading. The effect of mean stress is shown for cruciform and cover plate joints, and the effect of post-weld treatments (shot peening and tungsten-inert-gas dressing) is shown for some cover plate joints. The joints were in twelve alloys in the 5000, 6000, or 7000 series with fillers in the 5000 series. All welding process variables and geometries are detailed and the location of failure is indicated. A table summarises fatigue strengths at lives of a million and 10 million cycles for stress ratios of zero and -1. Summary graphs compare the scatter bands for all joint types in all materials and also mean fatigue strength curves for all types in alloy 5083. A graph shows also the influence of parent alloy tensile strength on welded joint fatigue strength.
