Research On Welding Technology Of Nuclear Equipment Nozzle On "Squirrel Cage"

With the strategic choice of China’s energy structure adjustment, Nuclear power with itsclean, safe and efficient features to become a preferred. November2007State Councilofficially approved the "national nuclear power development project planning (2005-2020)"pointed out: in2020, China’s nuclear power installed capacity of at least40million kilowattsof nuclear power equipment manufacturing industry into an unprecedented period of rapiddevelopment. The upper part of the third-generation nuclear power technology reactorpressure vessel (RPV) component is a key component of the entire reactor pressure vessel,the quality of the component manufacturing, and a direct impact on the completion of theentire reactor pressure vessel manufacturing and quality.This thesis will be by to take over the third-generation nuclear power technology RPVwelding flip device (squirrel cage) on the welding technology research in the correspondingwelding base metal, welding parameters, the structure and use of welding methods and thecorresponding welding equipment (squirrel cage)and several other aspects in detail, theformation of a more detailed welding process.Paper for the study of the status quo at home and abroad, as well as the content andmethods of this thesis, describes the value and significance of the characteristics of nuclearpower equipment manufacturing technology and its special manufacturing technologyCorrect and efficient application of the squirrel-cage, guarantee ABGH component ofthe successful completion, will reach completion of the third generation of nuclear powerdevelopment of new products, manufacturing goals, making the company a leading positionin domestic and international industry, nuclear localization play an important role inpromotingThe Squirrel Cage design principle and test proposal are defined by me. The weldingproposals and following are defined by me...
