Abstract: Transverse and longitudinal residual stress distributions in welded ferritic steel T-plate joints of two different plate sizes are presented. The stresses have been measured by the deep hole drilling (DHD) technique and by neutron diffraction (ND). The measured residual stress distributions are compared with an earlier independent measurement and with representative residual stress distributions provided in UK safety assessment procedures. It is found that the current safety assessment procedures BS 7910 and R6 are conservative.
