ようになる。[0003] This metal carrier is loaded and fixed to, for example, an exhaust gas system of an automobile engine after carrying a catalyst. However, since the metal carrier is exposed to vibration and high temperature during operation of the engine, not to mention the honeycomb body itself, The joint with the outer cylinder must also be strong. On the other hand, this carrier is rapidly joined to the ridged as it undergoes a rapid heat-quenching heat cycle in which it is rapidly heated when the engine is started and cooled when the engine is braked or stopped. In this case, large stress is generated in the vicinity of the joint between the outer cylinder and the honeycomb body, thermal fatigue is likely to occur, and buckling or peeling occurs.

For example, in Japanese Patent Publication No.
As disclosed in Japanese Laid-Open Patent Publication No. 3,312,944, a method of providing a brazing area only in the vicinity of at least one end face side of a honeycomb body as disclosed in JP-A-3-44466, There has been proposed a structure in which a honeycomb portion and a flat plate are joined to each other to form a flexible joint structure, or a structure in which a honeycomb body and an outer cylinder are locally joined, such as Japanese Utility Model Laid-Open No. 62-194436. However, each of these examples requires a means for properly supplying and adhering the brazing material to the specific contact portion of the flat plate-corrugated plate, and when the supply of the brazing material becomes excessive, the components of the joint plate are changed to cause corrosion resistance and corrosion resistance. High temperature strength will be deteriorated.

Japanese Patent Laid-Open No. 36-36 describes that diffusion bonding is performed. Due to the above-mentioned characteristics due to such sintering and diffusion bonding,
Alternatively, the work problem can be solved for the time being, but in order to obtain a large joint strength at the contact portion by these treatments, a considerable surface pressure is required on the contact surface of the flat plate-corrugated plate. In order to satisfy this requirement, in Japanese Patent Laid-Open No. 14747/1990, the outer cylinder accommodating the honeycomb body is squeezed to improve the contact between the flat plate-corrugated plate contact portion and the contact portion between the honeycomb body and the outer cylinder. Proposes to join.

ハニカム体の耐久性に影響する。As described above, many proposals have been made for diffusion bonding. However, not only the honeycomb body manufactured by a usual method but also the drawing effect when the outer cylinder is squeezed. Is small in the end face portion of the honeycomb body, and the end face portion flat plate-corrugated plate cannot be sufficiently brought into contact with each other. That is, the bonding is left unsatisfactory, but the durability of the honeycomb body is affected particularly when the end surface on the exhaust gas intrusion side is in such a state.

FIG. 1 (A) shows an example of manufacturing the honeycomb body 1, in which a flat plate 2 made of a corrosion-resistant and heat-resistant metal foil such as stainless steel and a corrugated plate 3 corrugated on the flat plate are superposed on each other to form a spiral shape. It is wound into a honeycomb body having a predetermined size.
Prior to winding, a joining inhibitor 4 is applied to the crests of the front and back surfaces of the corrugated plate 3, that is, a specific portion of the portion where the corrugated plate comes into contact with the flat plate so that the flat plate-corrugated plate will not be bonded in the subsequent diffusion treatment. Apply. In the figure, reference numeral 5 denotes a joining-preventing agent coating device that is provided so as to be able to come into contact with and separate from the honeycomb body manufacturing line. In this example, a roll transfer coating method is adopted, and the position of the coating roll 51 to be brought into contact with the corrugated sheet 3 is shown. By adjusting, it is possible to select the site where the anti-bonding agent is applied to the corrugated sheet. Thereby, the honeycomb body 1
Further, the joint portion and the non-joint portion can be intentionally formed, and the target stress relaxation structure can be obtained.

等公知の手段を採用しても良い。To the honeycomb body 1 manufactured as described above, a brazing material 6 is adhered or applied to a predetermined portion on the outer periphery of the honeycomb body 1 as shown in FIG. Insert. In this case, the brazing material 6 can be adhered or applied to the inner circumference of the outer cylinder 7 instead of the honeycomb body. The outer cylinder 7 is made of a corrosion-resistant metal (for example, stainless steel such as SUS430), and has an inner diameter slightly smaller than the outer diameter of the honeycomb body 1 or equivalent or slightly larger. That is, in the former case, a method of forcibly pressing (pressing) the honeycomb body 1 into the outer cylinder 7 and closely contacting it is adopted. Further, in the latter case, the honeycomb body 1 can be inserted into the outer cylinder 7 relatively easily, but since the adhesion is poor in this case, as shown in FIG. Sandwiched between them and compressed / reduced in diameter from the outer periphery so as to be closely integrated with the honeycomb body 1, and the flat-corrugated plate contact was also a point to be a linear or planar shape, and a good contact state is obtained. The diameter of the outer cylinder is not limited to the above method, and a known means such as a roller press may be used.

There is also. In particular, if there is a non-contact portion on the end surface on the exhaust gas inlet side, peeling occurs from that portion and this further spreads and becomes a structural defect. Therefore, in the present invention, as shown in FIG. 2 (E), At least one of the end faces 11 of the honeycomb body is irradiated with the laser beam 12 in the direction of the arrow and almost on the entire face, and sufficient end face bonding is performed. FIG. 3 shows a state of an end face joined by irradiating a laser beam, and the adjacent points of the flat plate 2 and the corrugated plate 3 are joined by the weld metal 13 melted by the laser beam.
