Fatigue crack growth rates in high pressure hydrogen gas for multiple X100 pipeline welds accounting for crack location and residual stress

•Evaluated fatigue crack growth rates (FCGR) in X100 steel welds and HAZ in H2.•Corrected FCGR curves for residual stress effects by calculating Kres.•Compared FCGR of high strength welds to low strength welds in H2 from literature.•Compared magnitude of residual stress in coupons to suggested standards.
