反应堆压力容器接管-安全端异种钢焊缝直射纵波超声检测方法
Straight Wave UT Technical for Dissimilar Weld of Tube to Safe-End in Reactor Pressure Vessel
摘 要
反应堆压力容器(RPV)接管-安全端对接接头属奥氏体-铁素体异种钢焊缝, 因晶粒粗大的原因实施超声检测难度大。针对现有斜射纵波检测方法对面状缺陷检测能力不足的情况, 结合焊缝具体结构特点提出了一种以安全端端面为探伤面的超声直射纵波检测方法。试验研究结果表明, 该方法对垂直于焊缝表面的面状缺陷检测效果较好。该方法可与斜射纵波检测方法组合使用, 在RPV制造阶段有推广应用价值。

Abstract
Tube to Safe-End joint in Reactor Pressure Vessel(RPV) belongs to Austenite-Ferrite type Dissimilar Weld. It is difficult to perform UT because of its coarse grain structure. Considering deficient detectivity of planar defect by angle longitudinal wave technical, a straight longitudinal wave technical which takes Safe-end as scanning surface is put forward based on Joint structure. Experiment and research indicate it has good detectivity of planar defect which is vertical to the weld surface. This technical may be applied in manufacture stage of RPV Combining with angle longitudinal wave technical.
