Localised high-pressure rolling of welded joints in structural materials is currently being investigated as an industrially relevant means of eliminating harmful residual stresses which form during the welding thermal cycle, with promising initial results. It is proposed that the residual strains around such joints be mapped using ENGIN-X, allowing a more detailed assessment of the effects of rolling on the stress distribution, selection of optimal roller geometry, investigation of the combined effect of residual stress and weld bead profile modification, and verification of computational modelling results.
