The reason why the bonding strength is insufficient is
This is because the junction depth is very shallow.

妙な違いとなって現れ、製品の外観性に問題がある。That is, the techniques described in the above items (A) and (B) have the following problems. (1) It is necessary to perform friction stir welding on both the front and back surfaces, and after performing friction stir welding on one surface from above, it is necessary to invert the hollow panel structure. Therefore, productivity is low and manufacturing cost increases. (2) When friction stir welding is performed on both front and back surfaces, an undercut trace with an arc-shaped pattern generated by the rotation and movement of the bottom surface of the rotating tool remains on both surfaces. It is necessary to form the outer surfaces on both sides of the part in advance so as to be slightly higher than the surrounding surface, and to perform grinding and polishing so that the undercut trace disappears after the friction stir welding. For this reason, the number of processes increases, the productivity decreases, and the equipment cost, running cost, maintenance cost, etc. of the grinding / polishing processing equipment increase. (3) In order to prevent the joints from opening due to friction stir welding to prevent joint defects, it is necessary to restrain both sides in the width direction with an appropriate restraining force. Requires a stir welding device. (4) Deformation and buckling of the rib due to the pressing force applied to the upper surface of the butted portion by the friction stir welding rotary tool in the axial direction, that is, the hollow portion side, or heat on the inner peripheral surface side of the vertical rib on both sides of the butted portion. There is a problem of occurrence of joint defects due to deformation, and in order to prevent the occurrence of such joint defects, the pressing force, the shape and dimensions of the ribs, the specifications of the friction stir welding rotary tool and the welding depth Some countermeasures were necessary, such as examining and deciding them in relation to each other. (5) In the case where three or more hollow extruded members are joined to each other in the width direction at the time of manufacturing a wide hollow panel structure, the number of butted portions on both front and back surfaces is the same. Very high, further reducing productivity and increasing manufacturing costs. Also, there is large mechanical deformation caused by thermal deformation or inversion after friction stir welding on the upper surface side. (6) the (2) due to the section in question, before stir welding rubbing friction, pre-anodizing treatment decorative surface and comprising a surface in the product of the hollow panel structure, such as electrolytic coloring treatment and electrodeposition coating process There is a problem in performing surface treatment.On the other hand, when the above-mentioned grinding and polishing treatment is performed after friction stir welding, and then these treatments are performed, since the material is a wide material, large processing equipment is required. Required, which increases equipment costs and maintenance costs. Also, there is a subtle difference in the surface state between the grinding / polishing part and other parts as they are extruded, and this subtle difference in the surface state is particularly significant in the case of anodic oxidation, electrolytic coloring, electrodeposition coating, etc. In the case of the treatment, a slight difference in the color tone and glossiness of the surface appears, and there is a problem in the appearance of the product.

It is necessary to prepare a joint consisting only of the upper surface plate 160u from which the vertical piece 161 is omitted from 60, and to set this during the friction stir welding operation, which takes time and effort to manufacture and set the joint, which increases the manufacturing cost. (B) It is necessary to perform friction stir welding at three places and three times, so that the work time is long, the productivity is reduced, and the production cost is increased.

As shown in FIGS. 5 (a) and 16 (a), the thin ribs between the outer surface of the stirring pin 4 and the inner peripheral surface of the vertical ribs of the hollow extruded section are spread outward. When the amount of deformation is large and the amount of deformation is large, the increase in the inner volume at the bottom of the joint at the upper surface of the upper face plates 1up and 1up on both lower sides of the stirring pin 4 becomes large enough to be seen. Therefore, FIG.

Therefore, as shown in the right diagrams of FIGS. 15B and 16B, even if the metal is insufficiently replenished to the bottom of the joint by plastic flow, the shortage is not so large. As a result, a point-like defect dfs is generated at the bottom of the joint so as not to be visually discriminated.

ある。The findings from Table 7 of Example 6, Table 8 of Example 7, Table 9 of Example 8, and Table 10 of Example 9 are summarized as follows. (1) The thickness w 2 (mm) of the minimum thickness portion of the vertical rib at the abutting portion of the aluminum-based hollow extruded profile is equal to or more than the first deformation / buckling limit thickness w 2A (mm) defined by the above equation (1). In the case of the above, if the thickness is smaller than the second deformation / buckling limit thickness w 2B (mm) defined by the above equation 2, a large joint defect that can be visually recognized is generated or the joint becomes impossible. Two
When (mm) is equal to w 2B (mm), a defect that cannot be visually identified is generated. From this, assuming that the occurrence of a defect that cannot be visually discriminated is allowed, and to prevent the occurrence of a joint defect that can be visually discriminated, w 2 ≧ w 2A and w 2 ≧ w 2B There is a need to. (2) Even when the condition of w 2 ≧ w 2B is satisfied as described above, w 2 is equal to the first buckling limit thickness w defined by the above equation (1).
If lower than 2A generates large joints possible defects determination visually, w 2 is the degree of defects occur it could not be determined visually, if equal to the w 2A. From this, assuming that the occurrence of defects that cannot be visually discriminated is allowed, and to prevent the occurrence of joint defects that can be visually discriminated, w 2 ≧ w 2A and w 2 ≧ w Must be 2B . (3) In order to prevent occurrence of a joint defect that cannot be visually identified, it is necessary to satisfy w 2 > w 2A and w 2 > w 2B .

Approximately 1/3 of the operation time of Comparative Example 2 and approximately 1/6 of Comparative Example 2. (b) The deformation amount of the hollow panel structure according to the method of Example 1 was 0.5 mm, which was as small as 1/4 of the deformation amount 2.0 mm of the hollow panel structure according to the method of Comparative Example 1. 2.

mm, which is remarkably smaller than 1 /. 1 as in the comparative example
In the case of joining in pairs, the joint deformation amount is added, and the deformation amount of the entire product panel becomes large. However, when the entire panels are joined at the same time as in the embodiment of the present invention, the amount of deformation of the entire product panel is small because there is no addition of the amount of deformation as described above. Furthermore, since the center material into which the friction stir welding rotary tool is pushed into the left and right joints is given reverse strain, the amount of joint deformation is further suppressed.
