In a method for manufacturing a bonded part (19), consisting of an aluminum sheet (7) and an aluminum foam layer (12), molten aluminum foam (4) is placed directly on the preheated aluminum sheet (7). This produces diffusion welding between the aluminum sheet (7) and the aluminum foam (4) and thus produces a permanent bond. Compared to subsequent gluing of aluminum foam plates and aluminum sheets, the method according to the invention is highly economical.

Dans un procédé pour la fabrication d'un élément composite (19) se composant d'une tôle d'aluminium (7) et d'une couche de mousse d'aluminium (12), la mousse d'aluminium en fusion (4) est directement appliquée sur la tôle d'aluminium préchauffée (7), ce qui provoque un soudage diffusif entre la tôle (7) et la mousse d'aluminium (4) et, par conséquent, une liaison durable. Comparé à un collage postérieur de plaques de mousse d'aluminium et de tôle d'aluminium, le procédé décrit dans cette invention est caractérisé par une haute rentabilité.
