め、接合後にこの部材を取除く作業が必要であった。In the conventional friction stir welding apparatus, during the welding operation, the region of plastic flow caused by the shoulder of the welding tool is prevented from being discharged to the surface of the workpiece. However, when joining workpieces having a difference in plate thickness, the joining conditions, that is, the joining tool insertion depth, are set based on the thinner workpiece surface in order to prevent defects. As a result, the member is discharged from the shoulder from the thicker workpiece surface, and a burr-shaped member is generated at the end of the bead. Therefore, it is necessary to remove the member after joining.

にほんのわずかに接する様に離れている。(Embodiment 1) FIG. 1 is a side view of a welding tool according to the present invention, and FIG. 2 is a plan view of the welding tool as viewed from below. The joining tool 1 includes a pin 2 having a small diameter, a projecting shoulder 3 having a medium diameter, and a cylindrical shoulder 4 having a large diameter for cutting. Reference numeral 17 denotes a cutting blade whose tip is obtuse. FIG. 3 shows the Al or A using the joining tool of FIG.
FIG. 4 is a cross-sectional view of a welded part during joining for joining butt alloys. During joining, the joining tool 1 is moved along the joining surface 6 while the pins 2 and the tips of the projecting shoulders 3 are inserted into the joining surface 6 of the extruded profile 5 according to the joining depth of the extruded profile. To join. The depth of the welding tool is the same as the welding depth. As shown in FIG. 3, the welding tool 1 is tilted about 3 degrees so as to open to the workpiece with respect to the welding direction 1 and rotated in the direction of FIG. The extruded members 5 are joined together by the pins 2 and the projecting shoulders 3,
Without the cutting blade 17 of the present embodiment, the discharging member 11 formed as shown in FIG. 6 generated by this joining is removed by the cutting blade 17 provided at the tip end of the cylindrical shoulder 4. is there. Therefore, the step of removing the discharge member 11 after the joining can be omitted. In particular, although the extruded member 5 is used as an outer plate member of a ship or a railway car, the joining length is long, so that the effect of eliminating the step of removing the discharge member 11 after joining is great. The distance 18 between the cutting blade 17 and the protruding shoulder 3 is separated so that the cutting tool 17 is slightly in contact with the extruded profile 5 so that it does not bite into the joining surface when the joining tool is inclined as shown in FIG. ing.

The extruded profile 5 is composed of a plate 9 and ribs 8. The plurality of ribs 8 are arranged in the joining direction of the plate 9. The material of the extruded profile 5 is aluminum alloy A6N01.
It is. When the extruded members 5 are butt-joined, the ends of the extruded members 5 are butt-joined as shown in the figure. The extruded profile 5 is joined by inserting the joining tool 1 into the joining surface 6 and moving the joining tool 1 along the joining surface 6 while rotating the joining tool 1.

た。FIG. 5 is a sectional view of a joint before joining. The shape of the joint is such that a trapezoidal projection 10 is provided near the joint surface 6 to increase the thickness of the joint. This is because A6N01 is an age hardened alloy and the strength after joining is reduced. Therefore, the thickness of the joining portion is increased to secure a predetermined joining strength. However, since the extruded profile 5 has a lower dimensional accuracy of the plate thickness than a general rolled material, a step is likely to be formed on the joining surface 6 as shown in the figure. FIG. 6 shows a cross-sectional view after bonding. When friction stir welding is performed on a joint having a step in the thickness of the joint, a discharge member 11 is generated at the end of the bead 7 on the thicker side in order to set the joining conditions according to the smaller thickness. . However, by using the joining tool shown in FIG. 1, the high-temperature discharge member 11 could be easily removed while joining.
