This paper presents the results of a major joint industry project which investigated the influence of weld profile on the fatigue performance of tubular joints. Fatigue tests were performed on steel tubular T-joints under in-plane bending, with the main aim of ``testing`` the value of the weld profile control measures laid down by AWS. The range of welds produced enabled the effects of as-welded surface finish, weld leg length, and hence weld angle, and weld toe grinding to be explored. The results throw serious doubt on the value of the AWS weld profile control measures. However, they do confirm the potential benefit of the increased weld leg length if it moves the weld toe into a lower stressed region. Recommendations are made for changes to current design codes.
