Expanding on the second edition, the rating chart of this third edition includes an assessment of creep rupture damage on weld connections (circumferential and stub welds). This takes account of the high number of weld connections analysed by means of microstructure replication during periodic inspections. The metallophysical bases, presented in the second version, for developing creep rupture damage also apply to damage on weld connections.



Since creep damage on weld connections is localised, measures other than those taken for normally larger-scale damage in the base material generally have to be derived. For this reason, different nomenclature has been used in the rating charts in order to distinguish between damage to the base material and damage to the weld seam.
