Research on Non-buttering Butt Welding of Reactor Pressure Vessel
This paper carries out simulation test of non-buttering butt weld of the nozzle and safety end of the reactor pressure vessel,as well as performance test and non-destructive test of the welding joints,and verifies rationality of the proposed process and the reliability of the welding joint,so as to provide support for design and manufacture of the welding structure of the nozzle and safety end of the reactor pressure vessel.
