ABSTRACT:
A container complying with ANSI.RTM. N14.1 for containing uranium hexafluoride (UF.sub.6) which minimizes entrapment of contaminants, thereby increasing the decontaminability of the container. The container includes a cylindrical shell welded to two cylinder heads wherein the weld inside the container provides a smooth transition between the heads and the shell while complying with ANSI.RTM. N14.1. The heads and the shell each have an annular land. A plasma weld fully penetrates the opposing lands to join the heads and the shell. No backup bar is used during the welding process.
