Information × Registration Number 0215U003141, 0113U003441 , R & D reports Title Raise of longevity and operate reliability of carrying welded constructions of the supersize technical equipment working in conditions of moderate and low climatic temperatures popup.stage_title Head Lobanоv Leonid Mikhailovich, Доктор технічних наук Registration Date 21-01-2015 Organization E.O.Paton Electric Welding Institute of the National of Sciences of Ukraine popup.description2 On the basis of the development of ideas about the thermodynamics and kinetics of processes of hydrogen embitterment of welded joints and physical - mechanical processes of delayed fracture at low temperatures, the interrelation between the technological parameters of welding, chemical composition of the steel and welds metal microstructure characteristics and service properties of welded joints. The influence of technological factors on the state of stress in welded joints of high-strength steels and their resistance to cold cracking. Optimized design methods for assessing technological and fatigue strength of welded joints and developed new approaches to ensure the durability of the restored using parts surfacing operated under cyclic mechanical and thermal loadings. The results of studies used in the development of technological recommendations for welding, surfacing replacement and reduction of residual stress in welded joints.
