Abstract

The disclosure relates to an hydraulic accumulator, in particular a diaphragm accumulator, having an accumulator housing and a separating element disposed therein, which separates two media spaces from each other, wherein a weld seam is formed by a laser or electron beam welding process without any filler materials, in that at least a part of the wall parts delimiting the transition point are melted to form the weld seam, which closes off the transition point towards the surroundings, in a manner that is free of protrusions with respect to an outer circumferential surface of a connection element.
