This paper presents results of research on the propagation of fatigue cracks in structural steel sheet, subjected to a MIG welding process. The study was conducted on rectangular test pieces with 62.5 x 60 mm and 2 mm thick, MIG welded and non-welded. Samples were tested for fatigue crack propagation at the base material and welded metal. The results show a crack stop in the heat affected zone (HAZ), requiring greater amplitude of the stress intensity factor (KI) so the crack could propagate in a stable manner. Results indicate that the combination of adequate microstructure and residual stress in the HAZ are those factors which can stop the advance of the crack in MIG welded material.
