Abstract (en)
[origin: WO2020021189A1] The present invention relates to a method for welding a sealing, thermally insulating tank membrane, according to which there are present: - at least two metallic strakes (1, 2) of the sealing membrane, and - at least two metallic welding supports, a conductive strip (30) being inserted between said two welding supports, after which each of the two raised lateral edges of the two adjacent metallic strakes (1, 2) is sealingly welded, by resistance seam welding and in pairs, to one of the welding supports interposed between the adjacent raised edges.
