優れた接合法である。2. Description of the Related Art The cross-sectional shape of an aluminum profile panel (hereinafter referred to as a "profile panel") varies depending on the application, and some are symmetrical with respect to the center in the longitudinal direction.
For example, there is an asymmetric type as shown in FIG. These profile panels are manufactured by extrusion, and some have a length of about 2 m and more than 20 m. It is inevitable that such a long profile panel bends in its surface plane ("plane bend", see FIG. 1). The degree of this plane bending varies, for example, for a 2 m long shaped panel, the size of the bending (gap S in FIG. 1).
) Often reaches a maximum of 2 mm. When joining the above-mentioned profile panels with their long sides butt-jointed, a gap S is generated in the butt surface due to the above-mentioned plane bending.
The joining is performed by applying the force F (see FIG. 1) to correct the plane bending and to make the gap S as small as possible. However, since the profile panel is wide, the degree to which the plane bending can be corrected is limited. In fact, it is not actually possible to eliminate the gap S. On the other hand, in order to join the butted surfaces of aluminum profile panels, there are cases where welding such as MIG or TIG is used.
Although friction stir welding may be used, friction stir welding has advantages such as low thermal strain, clean joint surfaces and no need for finishing of joint surfaces. It is.

ても当て嵌まることである。[0003] The friction stir welding method is a well-known joining method (for example, Japanese Patent Application Laid-Open No. Hei 10-52771), but an embodiment in which the flat materials P, P are joined by the friction stir welding method is shown in Figs. It is shown in FIG. In this apparatus, the flat materials P, P to be joined are placed on the table 4, and the joining surfaces are strongly pressed against each other and clamped, and the joining tool T is moved along the joining surface while rotating at a high speed. The joining is performed by heating and plasticizing the joining portion with frictional heat between the joining surface and the pin 1 of the joining tool T and frictional heat between the shoulder 3 of the tool body 2 of the joining tool T and the joining surface. For example, the diameter of the pin 1 of the joining tool T used when butt-joining the flat materials P having a thickness of 2 to 5 mm is 5 mm.
This pin 1 has a gap S between the butting surfaces of 2 mm.
, The aluminum material plasticized by the frictional heat (hereinafter referred to as “plasticizing material”) fills the gap, and a partial depression occurs on the joining surface. In addition, since a minute gap is formed between the shoulder 3 and the gap, air is trapped in the gap, so that a small nest is formed at the joint at this portion, and the joining strength of the joint is reduced. There's a problem. On the other hand, it is only necessary to correct the plane bending by the pressing force F at the time of joining to substantially eliminate the gap S,
As mentioned above, this has limitations,
There is a problem that the joined panel is slightly deformed due to residual stress caused by the above-mentioned forcing force. Therefore, the gap S
When it reaches 2 mm, it can hardly be joined by the friction stir welding method. This tendency is remarkable as the thickness of the profile panel is larger and longer. Since the above-mentioned problem is caused by insufficient plasticization due to the gap S, the thickness of the joining portion is increased in advance, and the plasticized material is plasticized at the thick portion. To some extent, it can be solved by devising the cross-sectional shape of the joint end of the profile panel, such as supplementing
If the gap is large, for example over 2 mm, this is not a complete solution. Above, the problem of the prior art was explained by taking the case of joining the profile panels by the conventional friction stir welding method as an example, but this is for joining long profiles, plates and hollow panels by the conventional friction stir welding method. The same is true for the case where

It is an object of the present invention to devise a joining method so as to prevent a decrease in smoothness of a joining surface and a decrease in joining strength of a joining portion by filling with a material.

による接合強度の低下が防止される。The aluminum powder is filled in the gap S between the joining surfaces of the profile panels P, P whose long sides are joined to each other (otherwise, long profile, plate, hollow panel, etc.). In this state, when the joining tool T passes through the joint having the gap, the frictional heat between the joint of the plate material panel and the pin 1 and the shoulder 3 of the joining tool T (see FIG. 3) together with the joint of the plate material panel. The aluminum particles are heated and plasticized, and the joints of the plate panels mix with the plasticized plasticized material. That is, the aluminum powder particles filled in the gaps are shoulders 3 inclined at an angle Θ.
Is pressed down from above by the surface of
The pin 1 is pressed forward by the pin 1 so that the pin 1 and the lower surface of the shoulder portion 3 are strongly rubbed and generate heat, and are heated and plasticized in the same manner as the joint of the profile panel. It is mixed with the plasticized material in a plasticized state.
In addition, since the plasticizer is strongly pressed by the advancing of the pin 1 in a state where the plasticizer is pressed from above at the shoulder of the inclined joining tool, air is not entrained in the plastic, and therefore, the air is not entrained. There is no occurrence of the above nest. Therefore, the gap is filled with the plasticized plasticized material of the filled aluminum particles, thereby preventing the occurrence of depressions on the joining surface and the decrease in joining strength due to cavities.

で、この実施例では２ｍｍ未満のものを用いた。Next, an embodiment will be described with reference to FIG. FIG. 1 schematically shows an exaggerated connection state of the profile panel P having the cross-sectional shape shown in FIG. 2 by friction stir welding. The thickness t of the profile panel P is 2 mm.
(The thickness of the joint may be 4.5 mm), width B
Is a long member having a length of about 40 cm and a length of about 4 m. When the profile panel P is extruded, the frictional resistance of one end E1 with the extrusion die is greater than the frictional resistance of the other end E2. For example, there is a small bend toward the end E1 (arrow X) where the frictional resistance is large, and the bend often reaches a maximum of 2 mm. When the profile panels P are sequentially joined with their long sides butt-joined, if the above-mentioned bend is the same for all the profile panels P, there is theoretically no gap in the abutment surface. Since the shape and the size of the bend vary depending on the individual profile panels, gaps of various sizes are formed on the butted surfaces. In this embodiment, the gap is partially zero and partially reaches a maximum of 2 mm. In some cases, the maximum gap length of 2 mm reaches 10 cm. Now, the above-mentioned profile panels P, P are joined using a joining tool T having a diameter of the pin 1 of 5 mm, a tool shoulder diameter of 15 mm, a diameter of the main body 2 of 32 mm, and a forward inclination angle ３ of 3 degrees.
Friction stir welding is performed at a forward speed of 5 mm / s, but in a state where the profile panels P, P are butted and held by a clamp,
Chips A of the same material discharged by cutting of the milling machine
(See FIG. 3) is filled so as to be imprinted on the joint surface.
Regarding the cutting powder A, the particle size is not constant, and the smaller the particle size is, the higher the packing density by the imprinting becomes.
Those having a size of less than mm are screened with a sieve. It is more preferable to crush the swarf A into a powder having a particle size of less than 2 mm or a finer powder. Since it is desirable to increase the packing density as much as possible, in this example, one having less than 2 mm was used.

The joining surface becomes a smooth joining surface regardless of the presence or absence of the gap, and there is no trace of the gap. Also, no burrs were observed on the cross section of the joint, and there was no difference from that of the joint at the portion where the gap was zero. The above embodiment has a thickness of 2
No special measures are required to fill the gaps with aluminum powder particles, but if the plate thickness exceeds 5 mm, the aluminum powder particles will reach the bottom of the joint surface. Push the fine powder so that it is densely filled,
Or mix it with a liquid and make it into a slurry,
It is important to consider the filling method. As described above, the embodiment in which the present invention is applied to the friction stir welding of the profile panel has been described. However, the same applies to the case where the present invention is applied to a long profile, a plate, and a hollow panel.

である。[Effect] As described above, the gap between the butt joint surfaces is filled with the powder and then the friction stir welding is performed by a normal method using a normal welding tool, so that the presence or absence of the gap, Irrespective of the size, a uniform and smooth joining surface can be obtained, and the joining strength of the joining portion can be uniform for the entire joining line regardless of the presence or absence of the gap and the size of the gap. Therefore, it is not necessary to excessively correct the plane bending of the profile panel in order to reduce the gap between the joining surfaces,
Work set for friction stir welding is simple and easy, and workability and work efficiency of friction stir welding of profile panels are improved. Further, since there is no need to excessively correct the profile panel for performing the friction stir welding, no significant residual stress is generated by the correction, and a panel due to the residual stress (a panel in which a plurality of profile panels are bonded). Is also avoided. Therefore, it is possible to remarkably improve the quality of the joint portion of the panel formed by friction stir welding of the long shape material panels, and further, the quality of the entire panel. The same applies when the long member to be joined is a long shape member, a plate member, or a hollow panel.
