The integrity of welded structures used for the safe transport of people and goods, and for the containment of liquids and gases, depends on the load carrying capacity of the welded joints. The welded joint is a critical part of a structure, because it may contain certain local brittle zones and defects. Standard practice and the available data concerning fracture toughness testing show that the values of fracture toughness depend on the thickness and geometry of the specimen, crack depth, mechanical properties of the microstructure, loading rate, the mode of loading, and the temperature of testing. The differences in the mechanical properties between different weld metal regions obviously affect the strain distribution around the crack tip during the fracture test and hence influence the toughness value. The variation of constraint during testing has an additional effect on the fracture behavior of any weld joint. The strength mis-match and current width of weld joint have an effect on the stress and strain distributions in the vicinity of the crack tip. Both can contribute to a higher constraint in the weld metal. In a welded structure, the crack tip propagates through different microstructures, and the width of the weld may also vary. This can be an important reason for the difference found between the measured values of fracture toughness obtained by testing small-scale specimens and the welded structure itself. For through thickness specimens failure occurred in microstructure with lowest tensile strength. It is usually as-welded or partly re-heated weld metal microstructure. Welding by melting of parent metal has a direct effect on the trough thickness distribution of HAZ microstructures. Consequently, during the test different yield, ultimate tensile strength and also elongation has been measured. Distribution of the tensile properties in the longitudinal direction or UM case is more uniform than in the through thickness direction. In case of OM the effect is opposite, because in longitudinal direction two or several microstructure can be contributed to higher or lower strength of weld metal. The difference between strength of as-welded and re-heated microstructure is more significant in OM than in UM weld metal. Portion of the specified microstructures along the length of the specimen increases (re-heated) or decreases (as-welded) the strength and elongation of weld metal. It was found also that the width of the welded joint as a constraint parameter has an effect on the limit load, maximum load and achieved fracture toughness values of a welded joint. In the case of strength overmatched weld joints, the limit and maximum loads increase with constraint (weld joint width) decrease. On the contrary, in the case of a strength under-match welded joint the limit and maximum loads decrease and constraint (weld joint width) increases.
