る。In order to solve the above problems caused by fusion welding, Japanese Patent Publication No. 7-505090 (FP0615480B1) discloses a friction stir welding method. In the friction stir welding method, when joining members, a rotating rotating tool is inserted into the joint, and the material heated by the friction heat between the rotating tool and the joint material is moved relatively by moving the rotating tool. It moves to the rear of the rotary tool to perform solid phase bonding. Since it is solid phase bonding, the above problems can be basically solved.

形状に工夫する必要がある。However, in the friction stir welding method, since the rotating rotary tool is forcibly inserted into the welding material and moved, the welding material receives a large force from the rotating tool. For example, when joining an aluminum alloy having a thickness of 5 mm, the force received by the joining material is about 1000 kgf. Therefore, it is important that the joining material is rigidly supported by using a strong backing material such as a steel plate. This can be achieved relatively easily with flat plate joining, but in the case of corner joining, it is necessary to devise the joint shape.

Outer-joint joining, slight unevenness occurs on the outer surface of the joining portion, because the joining material receives the force received from the rotary tool rigidly, for example, the backing materials 8 and 9 as shown in FIG. There is a problem that it needs to be arranged so as to withstand the force and is complicated.

しい。FIG. 4 is a sectional view for explaining the corner joint friction stir welding method of the present invention. That is, the protrusion 17 is arranged in the corner portion of the pair of joining materials 15 and 16, and these are fixed to the backing member 18 rigidly by a clamp mechanism (not shown). Next, the rotating tool 19 which rotates is inserted as shown in FIG. 5, and the rotating tool 19 is further moved along the corners to join them. The protrusion 17 is not formed integrally with the material 16 to be bonded, but is made of the same material as the material to be bonded,
The materials to be joined are joined together at the same time as the joining, and push-up during joining is prevented. The width of the side of the protrusion 17 on the rotary tool side is preferably larger than the diameter of the shoulder of the rotary tool.

するのが好ましい。At this time, the protrusion 17 preferably has an inverted triangular prism shape having the same apex angle α as the angle α formed by the corners, and more preferably an inverted isosceles triangle. When performing friction stir welding, the material to be welded needs to be fixed to the rigid. For example, when the length of the material to be welded becomes long, it becomes difficult to fix the protrusion 17 to the rigid. Also, when the rotating tool is moved during welding, the material to be welded receives a force from the rotating tool even in the traveling direction of the rotating tool, so the rigidity of the protrusion itself is insufficient for elongated protrusions, and deformation or rising of the protrusions does not occur. Occur. Therefore, it is desirable that the protrusion 17 is integral with at least one of the pair of materials 15 and 16 to be joined. For example, in the case shown in FIG. 6, the protrusion 1
7 is formed integrally with the material 16 to be joined,
Pushing up at the time of joining is prevented. The width of the side of the protrusion 17 on the rotary tool side is preferably larger than the diameter of the shoulder of the rotary tool.

好ましい。FIG. 7 is a sectional view for explaining another corner joint friction stir welding method of the present invention. In the case shown in FIG. 7, the protrusion
17 (17a and 17b) is a part of the two members 15 and 16 to be joined. By thus integrating the protrusion 17 with the material to be joined, deformation of the protrusion 17 during joining can be avoided. The end surfaces of the joints 15 and 16 to be joined are inclined with respect to the flat plate surface, and triangular protrusions 17a and 17b are formed along the inclined surface.
And one side of the triangle of the protrusion is formed on the extension line of the inclined surface. The length of the sides of the protrusions 17a and 17b on the rotary tool side is preferably not less than half the diameter of the shoulder of the rotary tool.

材製造コストの低減が可能となる。Further, the thickness of the pair of materials 15 and 16 to be joined is t 1
And t 2 (≧ t 1 ), the height h of the protrusion 17 is preferably h ≧ t 1/2, that is, half or more of the thinner plate thickness of the pair of materials to be joined. This is because the shape of the rotary tool is increased by increasing the width w of the upper surface of the inverted triangular prism shape to some extent. That is, when the width w becomes small, the shape of the rotary tool becomes small and the strength cannot be maintained, and there is a concern that the rotary tool may be damaged during welding. The corner-joining member in which the above-mentioned projections are integrated with the material to be joined may be produced by, for example, extrusion molding. That is, by manufacturing the joining member by forming the holes of the extrusion die as described above, it becomes possible to reduce the member manufacturing cost.

D is preferably approximately equal to width w. This is because when the diameter D of the shoulder portion becomes extremely larger than the width w, the shoulder portion 20 bites into the materials 15 and 16 to be joined and cuts.

In addition, according to the present invention, it is possible to join the corner portions even if the corner portions are linear one-dimensional, planar curved two-dimensional, and arbitrarily curved three-dimensional.

That is, it goes without saying that the materials 15 and 16 to be joined and the rotary tool 19 may be in a relative relationship. In FIG.
Triangular protrusions 17 are provided on both sides of the end of the material to be bonded 21, and the material to be bonded 21 is bonded to both sides of the material to be bonded 23 which is a flat plate in the same manner as described above.

However, the force is suppressed by the protrusions provided on the material to be welded according to the present invention, so that the corner friction stir welding that does not have defects or irregularities and can cope with curved welding can be obtained.
