ABSTRACT:
Method of manufacturing an accumulator device including a shell portion having an open mouth and a cap member affixed over the open mouth after a bladder assembly has been secured within the shell portion of the pressure vessel. The method comprises in the provision of an exterior annular weld connecting the cap member to the outer wall portion of the vessel as well as an interior weld connection between the interior wall portion of the cap member and the upwardly directed end edge of the mouth of the pressure vessel. By locating the metallic skirt member which functions to support the bladder such that the top of the skirt forms a dam for containing the weld which secures the cap member interior to the uppermost edge of the pressure vessel, the possibility of weld fragments falling into the bladder causing damage to the latter is minimized.
