In this case, the surface plates 1a and 1b are formed of a plate made of aluminum, and the frame 2 is formed of an extruded member made of aluminum. The core member 3 is formed by extruding a cylindrical extruded member made of aluminum material or a strip made of aluminum material into a cylindrical shape. Note that, in this case, the aluminum material is a member made of an aluminum material that has a good magnesium content and a low content of magnesium, which is good in brazing property with a fluoride flux. The panel body 4 is formed by integrally joining the surface plates 1a and 1b, the frame member 2 and the core member 3 formed by the aluminum member in this manner by brazing. Therefore, even when the core material 3 is formed by bending an aluminum strip, the separated portions at both ends of the strip are joined by brazing after the honeycomb panel is formed, and the core 3 is completely removed. Become cylindrical. Any of the surface plates 1a and 1b, the frame material 2 and the core material 3 can be formed of an aluminum clad material using a brazing material on the surface thereof.
The aluminum clad material may not be used for any of the a, 1b, the frame material 2 and the core material 3, but the brazing material may be interposed between them, and the brazing material may be melted and brazed during the heat treatment. In this case, the flux is a non-corrosive flux such as KF + AlF3 or KAlF4 + K3AlF6.
+ Surface plate 1 using flux such as K2AlF5.H2O
a, 1b, the frame member 2 and the core member 3 are preferably joined. The mounting seat 7A is formed of, for example, an aluminum material block having a higher magnesium content and a higher strength than an aluminum material having good fluoride flux and brazing properties.

The recess 5 is formed by notching the face plate 1a and removing a part of the core material 3 or by removing the face plate 1a in advance and removing a part of the core material 3 before brazing. After forming, the panel body 4 is produced by brazing,
The mounting seat 7 </ b> A is inserted into the recess 5. As shown in FIG. 3, the fitting of the mounting seat 7 </ b> A is performed while the panel main body 5 is placed on the receiving stand 8 and fixed by a clamp or the like (not shown). Next, a probe 10 projecting from the lower surface of a cylindrical shoulder 9 held by a rotation holding means (not shown) is pressed against the upper surface of the contact portion between the surface plate 1a and the mounting seat 7A. When the probe 10 is moved in a horizontal direction along the joint while rotating the probe 10 at a high speed (for example, 1000 to 5000 rpm), the contact portion between the surface plate 1a and the mounting seat 7A is softened by frictional heat, agitated, and the metal moves. Welded by pressing in the direction 6 (friction welding)
Is done. In this manner, the mounting seat 7A is inserted and fixed at an appropriate position of the panel main body 4, for example, at a position near the four corners.

1) According to the first aspect of the present invention, the mounting seat is inserted into a recess formed by cutting out at least one of the surface plates and removing a part of the core material.
Since the mounting seat and the surface plate are joined by friction welding, the mounting seat can be inserted and fixed in the recess without reducing the strength of the mounting seat due to thermal strain. In this case, the surface plate and the core material are formed of an aluminum member, and the surface plate and the core material are integrally joined by brazing, so that the surface plate is compared with the case where the mounting seat is brazed at the same time. The amount of heat required for brazing the core material and the core material can be reduced (claim 2). In addition, an aluminum material having higher strength can be used for the mounting seat as compared with an aluminum material having good brazability with a fluoride-based flux, and further improvement in the strength of the mounting seat can be expected.

2) According to the third aspect of the present invention, at least one of the surface plates is cut out, and a side wall of the recess provided by removing a part of the core material is interposed between the surface plates. It is formed of a reinforcing member, and the mounting seat is inserted into the recess and the mounting seat and the surface plate or the surface plate and the reinforcing member are joined by friction welding. In addition to the above 1), the mounting seat can be more securely fitted and fixed in the recess. In this case, the mounting plate is simultaneously brazed by forming the surface plate, the core member, and the reinforcing member from aluminum members, and integrally joining the surface plate, the core member, and the reinforcing member by brazing. Compared to the case, surface plate, core material,
The amount of heat required for brazing the frame member and the reinforcing member can be reduced (claim 4). Also, for the mounting seat, aluminum material with higher strength can be used as compared with aluminum material with good fluoride flux and brazing property,
Further improvement in the strength of the mounting seat can be expected.
