核反应堆压力容器接管安全端异种金属焊缝自动超声检测技术
Automatic Ultrasonic Testing Technique for Safe-end Dissimilar Weld of Nuclear Reaction Presure Vessel Nozzle
摘要
Abstract
There is a safe-end dissimilar weld between the nuclear reactor pressure vessel nozzle and the primary system pipe,the microstructure of weld is coarse grain.Ultrasonic testing for this kind of weld is difficult,beacause anisotropic and acoustic deflection is obvious in ultrasonic detection,ultrasonic energy has great attenuation,and the noise is high.Base on the ultrasonic theory and practice experience,then develop reliably ultrasonic testing technique for reactor pressure vessel nozzle safe-end dissimilar weld,and the technique had been carried out in nuclear power plant.关键词
