摘要
Abstract
CAP1000 reactor pressure vessel tube socket is made of low alloy steel by submerged arc surfacing welding, in order to ensure the isotropic of microstructure and property for surfacing structure, it used the same material and welding process with CAP1000 products pressure vessel tube socket to simulate welding, and to perform tensile and impact test from three directions, including perpendicular to welding direction, parallel to welding direction, and the welding structure height direction. Test results showed the pressure vessel tube socket made by surfacing welding is with good organization performance, good welding performance, found no weld defects;the tensile and impact properties from three directions are equivalent.关键词
