摘要
分析了在核3级容器的制造过程中,对在弓形边缘板的产品见证件进行试验时,背弯试件出现裂纹的原因及采取的相应措施,并以RCCM为依据,重新进行了试验,从而使焊接产品见证件得以关闭。
This article analyzes the reasons for the presence of cracks on the samples taken from the witness welded products of the bow edge plate during the root bend test in the manafacturing of the3th grade vessels of nuclear industry,and puts forward the carresponding measures that should be adopted,and to renew the test in accordance with RCCM,as a result,the cracks on the witness samples of the welding products can be eliminated.
