The advantage of using HSLA steels in the case of structures subjected to cyclic stresses lies in an improvement in the local geometry of the weld tow or in the introduction of residual compressive stresses in the vicinity thereof. Recent bibliographical reviews (1) (2) show the advantage to be gained from using improvement techniques in order to increase the number of cycles needed to initiate a crack, or even to eliminate the conditions required for initiation.
