The aim of this investigation is to evaluate the influence on fatigue behaviour of the finishing of the bulge in a welded aluminium¿zinc¿magnesium alloy AA7020. It was determined that total or partial elimination of the bulge has very little influence on its behaviour, giving a very similar result on both cases, where one is better than the other by only 3%.
