The objective of this paper is to study the combined effects of weld metal undermatching and crack locations on the fracture behavior of transversely loaded butt-welded joints in high-strength steel. Surface-cracked tensile panels were instrumented with stain gages and tested with notch locations at the heat-affected zone (HAZ), base and 30 percent undermatched weld metals. It can be expected that for a given applied strain, the level of the strain concentration developed in undermatched weld region will be significantly lower in the high strain-hardening welds compared to the low work-hardening weld joint in high-strength steels.
