Weld joint can contain various types of flaws such as slag inclusions, gas pores or stick spots. From such flaws during the service a crack can initiate, grow slowly and finally lead to catastrophic failure. Fatigue behaviour of welded structure is complicated by many factors intrinsic to the nature of welded joints. However, the residual stresses as consequence of thermal multi-pass welding cycles have main effect on crack fatigue propagation. Effect of through thickness residual stresses on fatigue crack growth in threshold loading regime is going to be presented, and their effect on structural integrity of welded plate.
