A method for forming a bi-metallic structural bulkhead assembly (10) formed from at least two sections. A thin strip of metal (16), metallurgically similar, and weldable to, a plurality of lower metal sections (14) is explosion bonded to an upper metal section (12). The lower section(s) (14) are then welded to the thin metal strip (16), thus forming the structural assembly (10). The structural bulkhead assembly (10) may then be properly machined and subjected to an appropriate heat teatment process. Méthode permettant de réaliser un assemblage (10) structurel de cloisons bimétalliques à partir d'au moins deux sections. Une mince bande de métal (16), semblable au point de vue métallurgique à plusieurs sections métalliques inférieures (14) et soudable à ces dernières, est collée par explosion à une partie métallique supérieure (12). La (ou les) section(s) inférieure(s) (14) sont ensuite soudées à la mince bande de métal (16), ce qui permet de créer un assemblage structurel (10). On peut alors soumettre l'assemblage (10) structurel de cloisons à l'usinage et à un traitement thermique approprié.
