Abstract:
An improved method for manufacturing a metallic honeycomb body having channels running from a first end face to a second end face of the metallic honeycomb body, the improvement which comprises:performing one of winding, layering and looping at least partially structured sheet metal layers to form the metallic honeycomb body;applying a layer of rolling oil to the at least partially structured sheet metal layers after the at least partially structured sheet metal layers have been manufactured;heating briefly the metallic honeycomb body formed of the at least partially structured sheet metal layers coated with the rolling oil for removing volatile components of the rolling oil from uncovered surfaces of the at least partially structured sheet metal layers;applying a brazing powder that adheres to the rolling oil remaining on the at least partially structured sheet metal layers forming the metallic honeycomb body, whereby the brazing powder sticks directly to the rolling oil; andperforming a brazing procedure on the metallic honeycomb body.
