【摘要】：管子管板焊接是核電站一回路主設(shè)備蒸汽發(fā)生器制造過(guò)程中的關(guān)鍵工序,管子管板焊接質(zhì)量直接影響著蒸汽發(fā)生器的使用壽命和制造進(jìn)度。分別對(duì)二代改進(jìn)型壓水堆和三代壓水堆1000MW蒸汽發(fā)生器管子管板焊接工藝進(jìn)行介紹,比較了RCC-M規(guī)范和ASME規(guī)范對(duì)管子管板焊接要求的異同,針對(duì)焊接過(guò)程中出現(xiàn)的問(wèn)題,分析了缺陷產(chǎn)生的根本原因,對(duì)焊接參數(shù)重新進(jìn)行優(yōu)化,同時(shí)加強(qiáng)了焊接過(guò)程控制,得到了質(zhì)量穩(wěn)定、焊縫形狀和尺寸均滿足設(shè)計(jì)要求的焊接接頭。
[Abstract]:Tube-plate welding is a key process in the manufacture of steam generator for primary circuit equipment of nuclear power station. The welding quality of tube plate has a direct impact on the service life and manufacturing progress of steam generator. This paper introduces the welding technology of the second generation improved PWR and the third generation PWR 1000MW steam generator, compares the differences and similarities between the RCC-M specification and the ASME code for the tube-plate welding requirements, and aims at the problems in the welding process. The fundamental causes of the defects are analyzed, the welding parameters are optimized again, and the welding process control is strengthened to obtain the welded joints with stable quality and the shape and size of the weld meet the design requirements.
