場合、従来は、次の３つの方法で行っていた。PRIOR ART AND PRIOR ART PROBLEM TO BE SOLVED BY THE INVENTION For example, an automobile intake manifold is made of two or more metal materials and includes a substantially horizontal wax section and a substantially vertical wax section, and in the substantially horizontal wax section, A metal product in which the first metal material and the second metal material are brazed together with the insertion part of the second metal material inserted into the substantially horizontal cylindrical part of the first metal material. Conventionally, the following three methods have been used to manufacture:

後に溶着金属がろう付温度まで加熱されるため、溶接に
用いる溶加材としては、後工程のろう付温度よりも高い
融点を有するものを用いなければならず、したがって母
材となる金属材の材質が限定されるという問題がある。First, before brazing the part to be brazed that will become the approximately vertical brazing part, both metal materials are inserted with the insertion part of the second metal material inserted into the approximately horizontal cylindrical part of the first metal material. This is a method in which the welding is performed by arc welding, and then the substantially vertical brazing portions are brazed. However, in this method, the weld metal is heated to the brazing temperature after welding, so the filler metal used for welding must have a melting point higher than the brazing temperature in the subsequent process. There is a problem in that the quality of the metal material used as the base material is limited.

る。Part 2: After brazing the approximately vertical brazing area, the first
This is a method of welding both metal materials by arc welding with the insertion part of the second metal material inserted into the substantially horizontal cylindrical part of the metal material. However, with this method, parts that have already been brazed may get in the way and prevent the welding torch from entering.
There is a problem that the welding posture becomes inefficient, which limits the product shape and reduces productivity.
その３は、略垂直ろう付予定部位をろう付した後、第１

るという問題がある。Part 3: After brazing the approximately vertical brazing area, the first
This is a method in which both metal materials are brazed by torch brazing with the insertion portion of the second metal material inserted into the substantially horizontal cylindrical portion of the metal material. However, with this method, it is necessary to use flux during torch brazing, and it is necessary to remove the flux from the brazed portion, so there is a problem that the work becomes troublesome.

である。Means for Solving the Problems The method for brazing metal materials according to the present invention includes a first metal material having a substantially horizontal cylindrical portion, and a second metal material having an insertion portion inserted into the substantially horizontal cylindrical portion of the first metal material. When brazing the metal material with the insertion part of the second metal material inserted into the substantially horizontal cylindrical part of the first metal material, the inner circumferential surface of the substantially horizontal cylindrical part of the first metal material, A brazing material is interposed between the outer circumferential surface of the part of the second metal material to be inserted into the cylindrical part, and a brazing material is further placed on the outer periphery of the substantially horizontal cylindrical part of the first metal material. The first and second metal members are brazed to each other by fitting a metal ring having a small coefficient of thermal expansion over the metal ring.

か一方をろう材層で覆っておいてもよい。In the above, it is preferable to use a brazing filler metal formed entirely in a ring shape from a brazing filler metal sheet, but it is also possible to use a brazing filler metal formed into a ring shape from a plating sheet. When using a plate made of plating sheet, the thickness of the core material is:
It is best to make the thickness of the core material thinner than that of a normal plating sheet. Further, the brazing material may be formed integrally with at least one of the substantially horizontal cylindrical portion and the insertion portion. That is, at least one of the inner circumferential surface of the substantially horizontal cylindrical portion and the outer circumferential surface of the insertion portion may be covered with a brazing material layer.

よい。In the above, it is preferable that the difference in coefficient of thermal expansion between the first metal material and the metal ring is about 4×10-' to 20×10-6/'C. Specifically, when the first metal material is made of aluminum, the metal ring is preferably made of an iron alloy such as stainless steel, a Ni alloy, brass, or the like.

The difference is 0.
It is preferably within the range of 2 to 3.0 mm and 0 to 0.05+Im.

The maximum allowable thickness of the ring-shaped filler metal is (DI-Do)
/2+Ommaro, minimum allowable dimension is (DI-DO)/2-0
．． It is better to set it to 05+g*. Furthermore, the length of the brazing filler metal in the axial direction is preferably about 1111 times longer than the overlapping length of the substantially horizontal cylindrical portion of the first metal material and the insertion portion of the second metal material. As the metal ring, one that is integrally molded into a ring shape, and one that is made into a ring shape by bending a band shape are used.

その結果溶融ろうの流下が防止される。According to the method of the present invention, the thermal expansion of the substantially horizontal cylindrical portion of the first metal member in the radial direction outward is suppressed by the metal ring during heating during brazing, and the thermal expansion of the first metal member is suppressed by the metal ring. The difference between the inner circumferential surface of the substantially horizontal cylindrical portion and the outer diameter of the insertion portion of the second metal material becomes small, and the molten solder flows between the inner circumferential surface of the substantially horizontal cylindrical portion of the first metal material and the second metal material. It stays between the outer peripheral surface of the insertion part of the metal material,
As a result, molten solder is prevented from flowing down.
