ABSTRACT:
A method of fabricating a metal pressure vessel for a metal oxide-hydrogen battery. A straight length of metal having a generally T-shape cross section is formed into circular configuration and the abutting ends of the strip are welded together to form a ring that includes a generally circular body portion and a flange or fin which projects radially outward from the body portion. The welded ring is expnded radially outward to precisely fit the open end of the shell of the vessel and the ring is then assembled with the open ends of the shell and head with the ends of the shell and head abutting the outwardly extending fin of the ring. The ends of the shell and head are then welded to the ring to complete the assembly.
