Abstract

Residual stress measurements in a thick cylindrical steel electron beam (EB) welded sample are described. This is a particularly challenging problem because the residual stresses are distributed in a very narrow region, in and adjacent to the EB weld, when compared to more conventional welding methods. Several variations of the deep hole drilling (DHD) method were applied, including the original conventional method, an incremental approach and a newly developed over-coring method. It is demonstrated that the over-coring method can be used just as effectively as the more difficult incremental method.
