Abstract
A method for manufacturing a module with a hollow area by hot isostatic compression, including: making an assembly including superposed elements defining the hollow area, the assembly forming a sealed casing containing the hollow area, including at least one meltable obturation member separating the hollow area from the outside of the assembly; followed by hot isostatic compression of the assembly, to obtain diffusion-welding of its elements, by letting temperature and pressure conditions change over time to cause a rupture of the meltable obturation member allowing pressurization gas to penetrate into the hollow area.
