Title Residual stress in a steel high strength, thick section T-butt weld
Abstract Residual stresses in a structure are generated as a result of the various fabrication and welding processes used to make the component. Being able to quantify these residual stresses is a key step in determining the continuing integrity of a structure in service. In this work, the residual stresses around a high strength, quenched and tempered steel T-butt web to curved plate weld have been measured using neutron strain scanning. The results show that the residual stresses around the weld were dominated by the welding residual stresses, while the stresses further from the weld were dominated by the bending residual stresses. The results demonstrated that the residual stress predictions given in Standards, such as BS7910, are extremely conservative. This has implications in industry where the standard profiles are used during weld inspections and in ongoing maintenance to evaluate the likelihood of failure. More realistic predictions would reduce the number of weld repairs required by overly conservative residual stress estimates.
