摘要
The invention relates to a process for the production of a welded joint for at least three components of a multiple butt joint. In order to create the welded joint in the multiple butt-joint by welding from one side only, and to allow components to be fitted very securely to the completely covered face, the multiple butt-joint is created in such a way that at least a first and second of these components which can be welded together are positioned with a gap along their common seam; both the said components are provided with a recess in the region of the seam, said recess being bounded by both components in the direction of shrinkage at opposing surfaces; the abutting end of the third component is inserted into the recess where it fits positively; and once this jointing process is completed, the first and second components are joined by a weld seam. It is proposed that the process should be used in the production of a transport and storage container for spent nuclear fuel holders.
