Hydrostatic tests were conducted on nine fabricated HY-80 steel hemispheres to observe the effects of residual stresses from cold forming and welding on elastic response and collapse strength. Nondimensionalized collapse data indicated that residual stresses due to welding play a significant part in the collapse strength of fabricated HY-80 steel hemispheres.
