PRODUCTION OF METALLIC CARRIER

PURPOSE: To produce a metallic carrier for purification of exhaust gas excellent in durability and profitableness by interposing a platelike brazing filler metal material between the adjacent edge faces of adjacently disposed metallic honeycomb bodies and joining the honeycomb bodies with the brazing filler metal material in-between. CONSTITUTION: Two metallic honeycomb bodies H1 , H2 are adjacently disposed in metallic casing C in the axial direction, a platelike brazing filler metal material A is interposed between the adjacent edge faces of the honeycomb bodies H1 , H2 and the honeycomb bodies H1 , H2 are brazed with the material A in-between to produce the objective metallic carrier MS. Since the adjacent edge faces of the honeycomb bodies H1 , H2 are joined with the material A in-between under satisfactory strength, brazing parts can be diminished as a whole, a flexible structure is imparted to the whole and the whole is made excellent in thermal stress and thermal shock resistances The amt. of an expensive high- temp. brazing filler metal used can be reduced.
