Abstract	In this investigation A-514 F steel butt welds which contained defects such as inadequate joint penetration (IJP), or incomplete fusion, were strained in tension to failure. The load deflection data from each test was used to determine the value of the J-integral at maximum load. A limit load analysis was developed for the welds which predicts three regions of tensile behavior depending upon the width of the IJP: high toughness (IJP unimportant), transitional, low toughness (IJP dominates behavior). The size of IJP defects which define the boundaries between these regions were defined as 2a amd 2a and could be predicted by the limit load analysis. The use of the elastic-rigid plastic approximation for the J-integral allowed a fairly accurate relationship between deflection or strain at maximum load and toughness to be developed for the low toughness region of behavior. The use of limit load concepts allowed the ultimate tensile stress to be bounded in the transition and low toughness regions.
