ML00005 — Environmental Hydrogen Damage in Ti PipeM - Unalloyed TitaniumP - Longitudinal Seam Welded PipeAp - PipingCd - Hydride Formation
Region of the localized thinning at the weld metal, in a metallographic section, as polished. In the base metal the hydride layer is continuous and no thinning is evident (left side of the figure) and in the weld metal it is detached and cracked (right side of the figure).
