The results indicate that repair weld design parameters in terms of repair length, depth, and width are of critical importance to the mitigation of residual stresses.   When a short length weld repair was introduced at the mid-length of the initial butt-weld in the same specimen (Fig. 1a), this resulted in a strongly varying pattern of transverse residual stress surrounding the repair, as seen in Fig. magnitude of transverse tensile residual stresses in the region of the repair was high and approached that of the longitudinal stress component (Fig. 2b).Cited by:   An integral part of the certification of a new repair technique involves the assessment of residual stresses and, in work that underpinned deployment of the FTHP process, residual stresses were measured in five specimens of low pressure steam turbine steel conforming to the German specification SEW Grade 26NiCrMoV (ASTM A Class 5–7 Cited by: 2.   The maximum and minimum normal residual stresses were and − MPa respectively (Fig. 6(e) and (f)). It is therefore clear from Fig. 6 that the maximum residual stresses were in the middle of the work-piece, directly under the bead, and not at the weld bead toe. The residual stresses were high in magnitude and this is attributed to restraint.

Residual Stress Formation in Component Related Stress Relief Cracking Tests of a Welded Creep-Resistant Steel M. Rhode, A. Kromm, D. Schroepfer, J. Steger, T. Kannengiesser Abstract. Submerged arc welded (SAW) components of creep-resistant low-alloyed Cr-Mo-V steels are used for thick-walled heavy petrochemical reactors (wall-thickness up to mm) as well as employed in construction of [ ]. Hence, understanding the residual stress distribution is important to evaluate the reliability of pipe joints with weld overlay repairs. The finite element results in this paper showed that, after deposition of the DMW nozzle and stainless steel welds, tensile weld residual stresses still exist at regions of the DMW through the thickness.   Weld residual stresses in nuclear power plants can lead to cracking concerns caused by stress corrosion. Many factors can lead to the development of the weld residual stresses, and the distributions of the stress through the wall thickness can vary markedly depending on the weld processing parameters, nozzle and pipe geometries, among other factors.
