TL;DR: In this article, the development of residual stress generally depends on the response of the weld metal, heat-affected zone (HAZ) and nearby parent material to complex thermo-mechanical cycles, and the evolution of local material properties and residual stress was investigated for each of these zones during the manufacture of a three-pass groove weld in SA508 steel.

TL;DR: In this article, the authors measured four steel components created by electron beam (EB) welding to obtain their residual stress distributions, and compared the predicted residual stresses with the measurements, and found that the peak residual stresses occur either side of the weld outside of the heat affected zone, with magnitudes corresponding to parent material yield strengths.

TL;DR: In this article, the authors present a review of techniques available for modifying/relieving residual stress levels in weldments, since it is well known that large tensile RS levels generated in welds can be detrimental in terms of fatigue, fracture resistance and environmentally assisted cracking (EAC).

TL;DR: In this paper, the authors describe experiments that characterise and quantify the localised perturbations in residual stress associated with both ramped and abrupt stop-start features in a multipass weld.

TL;DR: In this article, finite element modelling guidelines for the calculation of welding residual stresses were developed for the assessment of integrity structures containing defects in the UK nuclear power industry, which is applicable to austenitic stainless steel joints produced using arc welding processes.
