Abstract

The present invention relates to a method for manufacturing an integrated cylinder using welding or diffusion welding. More particularly, the present invention relates to a method for manufacturing an integrated cylinder, in which four annular metal disks each having a diameter that enables the four annular metal disks to contact and be overlapped with each other, are partially welded or diffusion welded, placed within a tool, and blow-formed at a vacuum state, with the result that the two metal disks located in the middle are formed into a reinforcing portion and the outermost and innermost metal disks are formed into an inner surface and an outer surface of the cylinder. Thus, the integrated cylinder may be advantageously manufactured through a simple process with improved reliability and reduced manufacturing cost.
