Residual stress determination has been carried out on production welds to provide engineering data. A parting out technique has been used in which a strain gauged through thickness slug of material is removed from the weld area. The centre hole technique has been used with the blind hole in the weld material. There were differences between the results from the two techniques and a fully penetrant bead on plate fatigue sample with the bead running axially was used in order to compare the two techniques in more detail. After parting out, the layer removal technique was carried out in order to provide a relatively detailed through thickness residual stress distribution in order to explain the differences between the results from the centre hole and parting out techniques.
