SEALING BARRIER FOR A VESSEL WALL

摘要

The invention relates to a method for fabricating a sealing barrier for a sealed and thermally insulating vessel wall, comprising the steps of: arranging a repeating structure comprising alternately a sheet metal strip and an elongate welding flange (9) connected to the supporting surface, such that the raised lateral edges (20) of the sheet metal strip are arranged against the adjacent welding flanges; welding the raised lateral edge (20) to the welding flange using a straight weld bead (26) along a first longitudinal portion (27); extending the straight weld bead by an end portion (28, 29) diverted toward an upper edge (32, 41, 43); and performing a sealed edge weld (31) along a second longitudinal portion of the sheet metal strip such that the edge weld (31) sealingly joins the end portion (28, 29) of the weld bead (26).
