A method of making a sheet metal panel having a configuration of interior cavities defined between a pair of partially unified sheets, characterized by: a. Applying a substantially uninterrupted, continuous layer of welding stopping material to an entire facing face of at least one of said sheets except a marginal edge portion extending substantially around the periphery of said facing face, said layer being of such thickness that it allows a relatively low quality joining of said sheets, b. Forming a semi-finished part by placing said sheets next to one another with said layer of welding stop material interposed therebetween, c. Hot-laminating said semi-finished part to simultaneously integrally unite said sheets on said marginal edge portion and to unify said sheets with a joint of low quality on the part of them covered with said material stopping so p, and d. Inflating said unified semi-finished part in the area of said low quality joint by injecting a fluid under pressure between a pair of retention matrices having cavities formed in them corresponding to the desired internal cavity configuration in said panel whereby said sheets expand in said cavities of the matrices and remain unified in the areas where said matrices are not recessed.
