A method for producing a metal structure, in particular a honeycomb body, especially for a catalytic converter, from at least partly structured, wound, intertwined or stacked sheet-metal layers, includes cleaning the structure in a vacuum in a cleaning chamber, transferring the structure to a process chamber, carrying out a connecting process which may be a brazing operation, transferring the structure to a cooling chamber, and cooling the structure to a predetermined temperature in a vacuum in the cooling chamber. The method is preferably carried out in a three-chamber apparatus and enables shorter production cycles, more economical use of energy, and favorable variation of the surface properties of honeycomb bodies, as compared with previous methods.
