ABSTRACT:
A process and an apparatus for producing a honeycomb body include forming a metallic honeycomb structure having cavities through which a fluid can at least partially flow, and bringing at least one end side of the honeycomb structure into contact with a metallic melt having a lower melting point than the metallic honeycomb structure. The process and the apparatus allow layers of sheet metal to be intimately and permanently joined in an advantageous manner in joining regions by placing at least one end face of a honeycomb structure of the honeycomb body in contact with a metallic melt which has a lower melting point than the honeycomb structure and contains aluminum, for example. A honeycomb body which is produced by the method or the apparatus is also provided.
