[first embodiment]
Referring to attached drawing, first embodiment of the invention is described in detail.As shown in Figure 1, in the engagement of first embodiment
In method, illustrated the case where structural body 1 to by the first metal component 2 and the engagement of the second metal component 3 with being formed.In addition,
" front " in explanation refers to and the face of the opposite side at " back side ".In the joint method of present embodiment, it is prepared work
Sequence, is overlapped process, face soldering operation and friction-stir process at groove formation process.
Preparatory process is the process for preparing the first metal component 2 and the second metal component 3.First metal component 2 is in big
Cause the metal component of cuboid.First metal component 2 is made of aluminum alloy.It is formed at the four corners of first metal component 2
Implement corner portion made of round corner machining.Second metal component 3 is shape identical with the first metal component 2 and material.
The solidus temperature of first metal component 2 and the second metal component 3 can be set as example, about 580~650 DEG C, in present embodiment
In, the first metal component 2 and the second metal component 3 are set as to 3003 alloys of ductile material, therefore, solidus temperature is about
643℃。
Groove formation process is either one shape in the coincidence face of the first metal component 2 and the second metal component 3
At the process of groove.In the groove formation process of present embodiment, groove 14 is formed in the front 13 of the first metal component 2,
And groove 24 is formed at the back side 23 of the second metal component 3.Groove 14 is outside the interior lateral edge of the outer peripheral edge of the first metal component 2
Periphery is formed as frame-shaped.The cross sectional shape of groove 14 is not particularly limited, but is in the present embodiment semicircle shape for section.?
In groove formation process, by main points identical with groove 14, groove 24 is formed at the back side 23 of the second metal component 3.
As shown in Fig. 2, being overlapped process is that the first metal component 2 and the coincidence face of the second metal component 3 is made to coincide with one another
When forming coincidence part J1, the process that the single layer soldering plate 4 of Al-Si-Mg class is clamped between coincidence face.Brazing sheet
4 be no brazing flux soldering specification, is the thin lamina formed by Al-Si-Mg class alloy brazed material.4 shape of brazing sheet
Size as configuration in the inside of groove 14,24.The thickness of brazing sheet 4 is simultaneously not particularly restricted, but is in the present embodiment
For example, about 20~100 μm.
In being overlapped process, brazing sheet 4 is clamped between the first metal component 2 and the second metal component 3 on one side, on one side
It is overlapped the front (coincidence face) 13 of the first metal component 2 with the back side (coincidence face) 23 of the second metal component 3.It is formed as a result,
There is coincidence part J1.
As shown in figure 3, face soldering operation is the process of carry out face soldering.Here, the Si in brazing sheet 4 is the content because of Si
Temperature that is different and making the liquidus curve of brazing sheet 4 declines and the element for improving the wetability in the soldering of face.When Si content
When less than 1.0 mass %, the temperature of the liquidus curve of brazing sheet 4 becomes excessively high, so that even if brazing temperature as defined in reaching, soldering
The fusing of plate 4 is also insufficient, thus a possibility that in the presence of that can not obtain sufficient soldering strength (cross-section stress).On the contrary, working as Si
When content is more than 12 mass %, got higher a possibility that (crystallizing out) primary crystal Si is precipitated in ingot bar central portion in casting process, i.e.,

Difference due to brazing temperature and retention time are different, but effect is insufficient, and it is (cross-section to answer possibly can not to obtain sufficient soldering strength
Power).On the contrary, when Mg content is greater than 5.0 mass %, by roller, the load becomes large when ingot bar hot rolling, or to generate edge broken
(Japanese: ear cuts れ) is split, therefore, cold rolling becomes difficult.If considering the processability of brazing material, Mg content is preferably lower.
Therefore, the Mg content in brazing material is in the range of 0.1~5.0 mass %.It is further preferred that Mg content is in 0.1
The range of~4.0 mass %.It may further be preferable that Mg content is in the range of 0.1~3.0 mass %.
