STRESS CONCENTRATIONS IN DOUBLE WELDED PARTIAL JOINT PENETRATION BUTT WELDS

Results are presented for photoelastic analyses of stress concentrations in square butt welds that contain a centrally located unwelded area or discontinuity. The discontinuity may be intentional, as in a butt joint design that specifies a partial joint penetration weld, or it may be a defect such as inadequate joint penetration. Two kinds of loading are considered, namely, pure tension and pure bending. In pure tension the stress concentration based on mean plate stress is independent of the depth of the discontinuity when the depth is small and increases very rapidly for depths larger than one-fifth of the plate thickness. A basis is suggested for plotting fatigue test data which should reduce the scatter normally found in such tests. In pure bending the critical stress remains at the toe of the weld reinforcement for all but the largest discontinuities.
