Peer- review under responsibility of the 6th International Conference “Fracture Mechanics of Materials and Structural Integrity” organizers During the welding process, Electromagnetic Interaction of Low Intensity (EMILI) was induced by applying axial External Electromagnetic Fields (EEMF) of 0 and 3 mT. Resistance to nucleation and growth of fatigue cracks was evaluated in Low Cycle Fatigue (LCF) regime to observe the short crack behaviour in a Fatigue Corrosion Test. The 3 mT EMILI was found to improve the resistance to localized corrosion in comparison with 0 mT. The resistance to crack initiation and fracture toughness were also improved with the application of the 3 mT EEMF due to the modification of the microstructural evolution during the thermal cycle inv lved in the welding process. © 2019 The Author(s).
