れている。2. Description of the Related Art Generally, a catalytic converter is arranged in an exhaust system of an automobile to purify exhaust gas. The metal honeycomb carrier of the catalytic converter is configured by inserting and joining a honeycomb body formed by alternately winding metal flat plates and corrugated plates into an outer cylinder. In manufacturing a metal honeycomb carrier, a method of reliably diffusion-bonding the honeycomb body itself and a method of reliably bonding the honeycomb body and the outer cylinder are required.

るという問題があり、採用し難い。A method for surely diffusion-bonding the honeycomb body itself is disclosed in, for example, Japanese Patent Application Laid-Open No. 14747/1990. After the honeycomb body is inserted into the outer cylinder, the outer cylinder is subjected to a die or the like. After squeezing, the corrugated plate and the flat plate forming the honeycomb body are diffusion-bonded.
In addition, it is desirable to integrate the honeycomb body and the outer cylinder by diffusion bonding. However, in this method, the contact area between the outer peripheral surface of the honeycomb body and the outer cylinder is large, so the contact pressure acting between them is insufficient. However, since the honeycomb body and the outer cylinder have different plate thicknesses, diffusion bonding between the outer peripheral surface of the honeycomb body and the outer cylinder is less likely to occur, and there is a problem that the bonding between the honeycomb body and the outer cylinder becomes insufficient. It is difficult to adopt.

At this time, since the temporary honeycomb body 2 is formed with a diameter smaller than the product size, a gap C is formed between the inner peripheral surface 3A of the outer cylinder 3 and the outer peripheral surface 2B of the temporary honeycomb body 2. It Therefore, the operation of inserting the honeycomb body 2 becomes extremely easy. In step S5, when the outer cylinder 3 and the temporary honeycomb body 2 are heated to a high temperature in the state shown in FIG. 8, the state shown in FIG. 9 is obtained. In the state of FIG. 9, the brazing foil material 6 is melted by heating and the temporary fixing of the temporary honeycomb body 2 is released.

化するまでの間、何らかのクランプ手段を必要とする。When the brazing foil material is partially attached, it is effective against alternating stress due to heat. When the brazing foil material is attached to the entire surface, the bonding strength between the honeycomb body 2 and the outer cylinder 3 becomes strong. Whether or not the brazing foil material is partially or entirely attached is selected depending on the application. Further, in the present embodiment, the temporary honeycomb body 2 is formed by joining the winding end 5A of the flat plate 5 and the brazing foil material 6 by resistance welding, but as shown in FIG. Flat plate 5 with organic adhesive 8 such as cyanoacrylate
The winding end end 5A can be temporarily fixed, or can be temporarily fixed with an organic tape 9 such as an adhesive tape, a craft tape, or a cloth tape. In this state, the brazing foil material 6 is attached to the honeycomb body 2. Also, the brazing foil material 6 can be attached before the temporary fixing. Even if the organic adhesive 8 is used, the organic adhesive 8 is partial and is heated at a temperature exceeding 1000 ° C., so that the organic substance is decomposed and becomes a molten brazing filler metal during heating. On the other hand, there is almost no adverse effect such as reduction of the bonding strength. Alternatively, the organic adhesive 10 containing a brazing material may be used.
Examples of the organic adhesive 10 include various organic adhesives such as vinyl acetate-based, acrylic-based, and epoxy-based adhesives. In this case, some clamping means is required until the organic adhesive 10 is cured.
