AB  - Welding is one of the most often applied joining procedures for different metallic
structures. Due to the nature of the process, i.e. heating, additional material (for some
methods), usage of protective atmosphere and cooling, it typically causes inhomogeneity in
the joint zone. This inhomogeneity influences the fracture behaviour, and can significantly
endanger the integrity of the welded structures. This work deals with micromechanical
criteria for initiation and development of ductile fracture in welded joints. These criteria are
applied within the framework of local approach to fracture, through experimental-numerical
procedure. Welded joints with a single weld metal or two different weld metals are
examined; the influence of constraint and heterogeneity (mismatch) is analysed. Also, the
defects in the heat affected zone are considered, as well as pipeline materials with sharp and
blunt initial defects. Micromechanical model CGM, complete Gurson model, is used for
modelling the damage initiation and development in the material.
