Abstract
The present invention relates to a method of assembly, in a furnace in vacuum conditions or under a neutral atmosphere, of two parallel plates leaving a closed internal space, consisting, in a first step, of performing a peripheral sealing by means of a first seal fusible at a first temperature, while maintaining open at least one opening of communication with the internal space and, in a second step, of closing the opening by means of a closing element with the interposition of a second seal fusible at a second temperature lower than the first temperature.
Claims15
A method of assembly, in a furnace in vacuum conditions or under a neutral atmosphere, of two parallel plates (1, 4) leaving a closed internal space (6), including:
- in a first step, performing a peripheral sealing by means of a first seal (5) fusible at a first temperature (T1), while maintaining open at least one opening (13, 13') of communication with the internal space;
- and
- in a second step, closing the opening by means of a closing element (14, 16, 16') with the interposition of a second seal (15) fusible at a second temperature (T2) lower than the first temperature.
