The present study evaluates the fracture behaviour of a pipe steel and compares the real scale pipeline assessment methodology (pipeline methodology) with the Guidance on Methods for Assessing the Acceptability of Flaws in Welded Structures (PD 6493). It is shown that the base metal is the toughest region and that the heat-affected zone is the least tough zone, that both assessment methods do not give the same result for the base metal, and that plasticity at the crack tip can toughen the welded joint.
