Measured and predicted residual stresses in thick section electron beam welded steels
David J. Smith,Gang Zheng,P. R. Hurrell,Christopher M. Gill,Benjamin M. E. Pellereau,K. R. Ayres,D. Goudar,EJ Kingston +7 more
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.

Development of Reduced Pressure Electron Beam Welding Process for Thick Section Pressure Vessel Welds
K. R. Ayres,P. R. Hurrell,Christopher M. Gill,K. Bridger,L. D. Burling,C. S. Punshon,Liwu Wei,N. Bagshaw +7 more
TL;DR: In this paper, the authors present results of micro-structural examinations, material property tests and residual stress analyses of RPEB welds in SA508 Grade 3 steel forgings, both in the as-welded condition and after post weld heat treatment.
