Abstract
A method for gluing and brazing a honeycomb structure includes at least one partially structured foil with a pitch and a wave height. The method includes the steps of choosing a mean brazing material diameter of a powder brazing material, said diameter being 15% smaller than the height of the wave; determining a minimum thickness of the glue strip according to equation; gluing at least partially structured foil within the width of the glue strip on at least part of the wave crests formed by the undulation; brazing the honeycomb structure. The invention also relates to a corresponding honeycomb structure that ensures satisfactory joint connections even when said structure is used in the exhaust systems of automobiles.
