A structure (10) in the shape of an aerodynamic panel in which adjacent cells (20a, 20b) are formed by placing a stack of three metal plates in a mould. After diffusion welding of the plates at the required locations, a first variable pressure is applied in a first series of cells (20a) formed between the outer plate and the intermediate plate and a second independent pressure approximately constant and lower than the first is applied in the other cells (20b) and on the inner face of the stack. Thus, this partially forms the cells and shapes the structure in contact with a complementary surface of the mould. The final conformation of the cells and the structure is obtained by applying a second pressure cycle in the cells and on the inner face of the stack.
