Abstract
The present invention relates to a method and device for assembling two elements spaced apart by means of a peripheral seal, consisting of adding a seal on a surface of a first element facing a surface to be assembled of a second element, bringing the assembly thus constituted, in vacuum conditions, to a temperature enabling the melting of the seal while temporarily maintaining, by means of spacers having a thickness higher than the thickness of the seal and distributed outside the seal, the surface of the second element distant from the seal, and enabling the elements to come closer to each other to assemble them, sealably, by means of the melting seal.
