After formulating a simplified model of under- and overmatched welded joints an analysis was made of stress at interface for the cases of perpendicular and non - perpendicular orientation of the zones (soft layer and hard layer) relative to the load action direction under tension. Conclusions from the theoretical analysis form a basis to an assessment of effort and fracture of the mismatched welded joints. Conditions for producing brittle and ductile fracture in mismatched welded joints in relation to geometrical conditions of the layer (W), expressed by k, and the mechanical properties of the layer materials, W e R , 0 R and equivalent stresses H s , v s are established in further experiments.
