Highlights
To assess cold cracking susceptibility of steel HAZ, it is necessary to estimate local hydrogen content and residual stress at a weld root that are in general numerically calculated by FEM and/or FDM
We have developed empirical formulae to calculate HAZ hardness, hydrogen diffusion coefficient and tensile properties
The thermal history may be calculated by FEM and/or FDM
