核燃料包装桶由桶体、桶底、桶盖、锁紧环、密封胶圈等组成。它要求在运输、储存过程中保证其密闭性,以防止内容物外泄造成污染事故。包装桶的制造工艺包括下料、成形、缝焊、组装、除锈、涂漆。其中缝焊、桶体与桶底咬边是两个关键工序,磨坡口、桶口成形与桶底咬接缝预翻边是其重要工序。详细地研究了制造工艺故障,建立了工艺故障树。找出并剖析了原材料、工艺参数、设备、工艺方法及操作是产生工艺故障的五个方面

Nuclear fuel barrel from the barrel, the bottom of the barrel, lid, locking ring, sealing ring and other components. It requires the transport, storage process to ensure its confinement, in order to prevent leakage of content caused by pollution accidents. Bucket manufacturing processes include cutting, forming, seam welding, assembly, rust, paint. Among them, the seam welding, the bottom of the barrel and the bottom of the barrel are two key processes, and the important processes of milling the groove, forming the barrel mouth and seaming the seam at the bottom of the barrel are important processes. A detailed study of the manufacturing process failure, the establishment of a process fault tree. Identify and analyze the raw materials, process parameters, equipment, process methods and operations are the five aspects of the process of failure
