Abstract
A device and a method of assembly by brazing or diffusion-welding under a gaseous pressure is provided to make structures for a nacelle of an aircraft turbojet engine such as an inner fixed structure. Sealing of the assembly space inside which the parts to assemble are disposed is provided by tie members exerting a mechanical pressure on mold elements. The tie members include jaws made of a first material and a holding element made of a second material. The first material has a thermal expansion coefficient higher than that of the second material.
