The influence of the temperature and exploitation time on the behaviour of a welded joint subjected to variable and impact load
Апстракт
This paper presents the analysis of the temperature and exploitation time influence on the resistant measure to brittle fracture of welded joint constituents of the new and exploited low-alloyed Cr-Mo steel A-387 Gr. B subjected to variable and impact load. The exploited parent metal is a part of the reactor mantle which has been exploited for over 40 years and is in the damage repair stage. Wohler’s curves are constructed, that is, fatigue strength as the resistance of the material to the crack initiation and the total impact energy, as well as the components, crack initiation energy and crack propagation energy at room and working energy are determined. Based on the research
results, the analysis of the resistance to brittle fracture represents the comparison of obtained values for characteristic areas of welded joint and justification of the selected welding technology
