摘要
Abstract
This paper focuses on the abnormal fluctuation of yield during the electron beam welding process of fuel rods.Considering that the main defects leading to the rejection of fuel rods are surface scratches and out-of-tolerance straightness,through analysis and research,it is clarified that the di-rect causes of the abnormal yield of fuel rods are the excessively large aperture of the welding tooling baffle,the excessive use of the welding top,and the design of the top bearing.By taking measures such as reducing the aperture of the baffle,determining the reasonable number of uses for the welding top,and designing the top bearing,defects can be controlled in a timely manner,the yield can be im-proved,the manufacturing cost can be further reduced,and a foundation can be laid for the subse-quent exploration of fuel rod manufacturing processes.关键词
