The formalisms of ETM were applied to a transverse welded wide plate with a crack in the weld metal. Both the base material and the weld metal were regarded as power law hardening materials. It can be shown that differences in the plastic properties of the weld metal and base material, respectively, significantly affect the CTOD. Quantitative relations are given for the CTOD of a crack in the weld metal normalised by the CTOD a crack in the base material would exhibit. An important result is that the characterisation of a non-matching weld metal by the matching factor M only is not sufficient since work hardening plays an important role. From this, requirements for minimum weld metal toughness can be established in order to make the toughness performance of the weldment no worse than that of the base material.
