ある。2. Description of the Related Art The following method has been proposed as a friction stir welding method, which is one of the solid-state welding methods. That is, FIG.
As shown in (1), a small-diameter pin-shaped probe (12) that is harder than the joining members (1) and (2) is provided integrally on the end axis of the large-diameter cylindrical rotor (11). The probe (12) is placed at or near the butted portion (3) of the two joined members (1) and (2) while rotating the rotor (11) at a high speed by using the joining device (10).
Insert Generally, the shoulder (11a) consisting of a flat surface on the probe side of the rotor (11) is inserted into the joining member (1).
Repeat until it touches (2). Then, the probe (12) is moved along the butted portion (3) with the probe inserted. Frictional heat generated by the rotation of the probe (12), or even the shoulder (11a) of the rotor (11)
The joining member (1) near the contact portion with the probe (12) is generated by frictional heat generated by the sliding between the probe and the joining member.
The probe (12) is softened and agitated by the probe, and the probe (12) is moved so that the softened and agitated portion receives the traveling pressure of the probe (12) and fills the passage groove of the probe. After flowing plastically in such a manner as to wrap backward in the direction of travel, the heat of friction is rapidly lost and the solidified material is cooled and solidified. This phenomenon is repeated sequentially with the movement of the probe (12), and finally the joining member (1)
(2) is joined at the butting portion (3).

Then, bonding is performed in a state where a backing material (4) made of an iron plate or an aluminum plate is pressed.
Further, as shown in FIG. 2, in order to securely join the joining members (1) and (2) to the back surface, the probe (12) is inserted deeply until it reaches the back surface of the joining members (1) and (2).

要であった。However, in the friction stir welding method described above, the probe (1) of the rotor (11) is used.
The softened aluminum is extruded from the tip of 2) to the back side and comes into contact with the backing material (4), and when the aluminum is cooled and solidified, the joining members (1) (2) and the backing material (4) are separated. It may stick. When these were fixed and could not be easily removed, it was necessary to further remove the backing material (4).

不都合が生じる。As shown in FIG. 3, when the insertion depth of the probe (12) is made smaller than the thickness of the joining members (1) and (2) so that the softened aluminum material is not extruded to the back surface, the backing material ( 4) can be prevented, but on the other hand, there is a disadvantage that root cracks occur on the back surface to lower the bonding strength.

A material that has low affinity for aluminum and does not adhere to the joining members (1) and (2) even after cooling and solidification is used. Specific conditions are that the softening temperature is higher than that of aluminum and that it is not softened by heat generated during joining and is chemically stable, or that the surface is rough and the contact area with softened aluminum is small. is required.
In the case of a high temperature stable material, the material is preferably stable in a high temperature range of 200 ° C. to 500 ° C., and in the case of a rough surface material, the surface roughness is preferably Rmax 3 μm or more. Specifically, examples of the material having excellent high-temperature stability include a carbon-based material such as graphite, and a metal oxide such as SiO 2 , Al 2 O 3 , ZrO 2 , and MgO. Among the carbon-based materials, graphite is particularly preferable because it has good lubricity with the probe (12), has little wear and damage to the probe (12), and hardly adheres to softened aluminum. Furthermore, those obtained by sintering and solidifying the carbon-based material or metal oxide powder as a main component have a rough surface according to the particle size of the powder, in addition to the high-temperature stability of each material. Therefore, it can be used particularly preferably, and what is generally used as a refractory brick corresponds to this. In addition, the refractory insulation materials for construction such as gypsum board, asbestos slate, and calcium silicate plate have high surface stability in addition to the individual materials having high temperature stability. Therefore, it can be suitably used. In addition, a metal material that was conventionally an unsuitable material to be fixed to the softened aluminum can be preferably used because the surface is roughened so that the softened aluminum is hardly fixed. The type of metal is preferably one having a softening temperature that is much different from aluminum, and is preferably an iron alloy such as iron or steel, or a copper alloy such as copper or brass.
