Fatigue of weldments with welding defects – defect sizing, crack nucleation and crack growth rate

Ultrasonic inspections of weldments in some existing bridges revealed the presence of cold cracks, slag inclusions, and porosities of sizes beyond todays acceptance criteria. We conducted a study on the prediction of the fatigue life of these weldments. This paper presents the models and main findings of the study. An...
