Material properties of welded joints of heavy forgings for nuclear power plants of type MIR 1200.
Original language description
The paper deals with the research, development and verification of the manufactory technology of selected welded joints for pressure vessels of primary circuit of nuclear power plants of type MIR 1200. Attention was focused on the influence of different welding technologies (SMAW and SAW) to mechanical and fracture properties. Four types of homogeneous welded joints (10GN2MFA - 10GN2MFA) were performed in order to simulate the effect of various PWHT procedures altogether with one heterogeneous welded joint of 10GN2MFA - 08CH18N10T steel grades. The basic mechanical properties (tensile and impact test) as well as unconventional mechanical properties (fracture mechanics, low cycle fatigue, stress corrosion cracking in the water environment at elevated temperature and pressure) were evaluated. Further, the thermal dependence of shear fracture was developed and the effect of the welding method on the transition temperature was assessed
