In previous work we presented models which can be used to estimate the yield and ultimate tensile strengths of ferritic steel welds. The work presented here deals with properties which are much more difficult to predict, the elongation and Charpy impact toughness. Whereas the models are found to be useful and emulate expectations from current physical metallurgy principles, it is clear that much more systematic experimental data are needed before the predictability becomes as good as the strength models of Part I. The software associated with the calculations is freely available on the world-wide-web.
