ESDU 77011 gives graphs of the stress in the loaded plate
plotted against endurance obtained from test data for constant
amplitude loading on welds in plates of between 1/4 and 2 inch in
thickness reported in a wide range of sources in the literature.
The joints were prepared with square, or single or double U or V,
ends and welded from both sides. Two graphs show the data for weld
toe failure cases, one for a fully-tensile loading and one for zero
mean stress. Both show 95 per cent confidence lines derived from a
statistical analysis. A third graph shows failures initiated at a
weld defect for both fully tensile and zero mean stress loadings,
again with confidence limits. The influence of weld defects is
discussed and a graph shows the reduction in defect-free fatigue
strength plotted against the reduction in cross-sectional area due
to defects. Also discussed are the effects of residual stresses and
size, mean stress, and weld bead shape.
