A welding and backing ring arrangement for the connecting of two cylindrical enclosure parts of a flameproof enclosure of an electric cell having stacks of electrodes arranged symmetrically to the weld seam is described. The ring consists of a rectangular hollow profile section (box profile) with an outwardly directed, approximately equatorially arranged collar. The ring is advantageously produced from two identical ring halves which are connected mirror-invertedly and the meridian cross-section of which has a hat profile. To relieve the weight, the axially perpendicular areas may be provided with breakthroughs. The wall thickness of the welding ring is to be approximately 50% of the wall thickness of the flameproof enclosure. |
