Fatigue tests were carried out on type A5083P-O Al–Mg aluminium alloy butt welded specimens by a test method which simulates the behaviour of large size welded structures having high tensile residual stresses by means of ordinary narrow specimens, containing low level residual stresses. In the tests, specimens were cycled down from a constant maximum stress of the yield strength of the material. The S–N data obtained in these tests were compared with corrected lines from S–N data for narrow specimens tested at R= 0 considering the presence of high tensile residual stresses and the proposed design curve in the draft British Standard BS 8118. It was found that the discrepancy between corrected lines and the data plots was not small and that the proposed design curve was over conservative in the high cycle region.
