AB  - The welded joint is heterogeneous in its microstructure, mechanical and geometrical properties, thus the stress field is affected by different factors as well as by residual stress. Therefore, special procedures are needed for experimentally determining the fracture toughness in plane strain, K-Ic, and the impact toughness, usually associated with difficulties in interpreting the measured values. Notched specimens are tested by instrumented Charpy in order to determine impact energy and crack initiation and propagation energies. The pre-cracked specimens are tested by standard, using three-point bending specimens, as geometrically closest to Charpy specimens. In both cases, the notch and crack are located in all various regions of the welded joint of the high-strength low alloyed steel NIONIKRAL-70. Analysis of the results includes speculations on the ratio of energies for crack initiation and propagation vs. fracture toughness.

AB  - Temperature and time effects on fracture toughness have been investigated for characteristic regions in a welded joint made of Cr-Mo steel A-387 Gr. B. Comparative analysis of fracture toughness values for characteristic regions in welded joint has been made for both temperatures (20 ºC and 540 ºC) and for old and new material.

AB  - Temperature and service time effects on A-387 Gr. B Cr-Mo steel weldment fatigue strength have been evaluated. To assess service time effect on fatigue strength, samples are take from 40 years “old” material, whereas temperature effects are followed by comparing fatigue strength of parent metal (PM) and welded joint (WJ) at 200 and 5400 C.

AB  - The influence of exploitation period and temperature on the fatigue crack growth parameters in different regions of a welded joint is analysed for new and exploited low-alloyed Cr-Mo steel A-387 Gr. B. The parent metal is a part of a reactor mantle which was exploited for over 40 years, and recently replaced with new material. Fatigue crack growth parameters, threshold value ∆Kth, coefficient C and exponent m, have been determined, both at room and exploitation temperature. Based on testing results, fatigue crack growth resistance in different regions of welded joint is analysed in order to justify the selected welding procedure specification.
