    Abstract: Disclosed is a friction stir welding technique which avoids occurrence of a dent, in a joining region, extending to a level beneath the joined surfaces. At end portions of the frame members (50, 60) to be joined, at the joining region, thickened parts which project toward the rotary body joining tool (70) are provided. Two adjoining thickened parts, of adjacent members to be joined, can form a trapezoid shape. The rotary body joining tool has a small-diameter tip portion and a larger diameter portion. The rotary body joining tool is inserted in the thickened parts. In a state where the rotary body joining tool has been inserted small-diameter tip end first, to a level where the larger diameter portion of the rotary body joining tool overlaps the thickened part but does not extend below the upper surface of the non-thickened surfaces of the members joined, the rotary body is rotated and moved along the joining region. Even when a gap exists between two thickened parts, a desirable joining can be carried out. After the joining, the remaining parts of the thickened parts can be machined so as to form a smooth surface.

    Abstract: A hollow frame member is constituted by joining two face plates 11, 12 in a truss manner by ribs 13, 13A, 13B. The end portions of the face plates are connected by one rib 13A. A face plate 21 of a second hollow frame member 20 is joined at a vicinity of an apex of the truss of the first hollow frame member 10. The face plate 12 of the first hollow frame member 10 is joined at a vicinity of an apex of the truss of the second hollow frame member 20. These joints are made by friction stir joining using a rotating tool 250. The load during friction stir joining is received by the ribs 13A, 13B (13A, 23B). Since this truss structure is provided, a lightweight structure and high rigidity performance can be obtained.

    Abstract: End portions of face plates 21 and 22 of a hollow extruded frame member 20 are connected by a rib 24 and are welded to end portions of face plates 11 and 12 of a second hollow extruded frame member 10 by friction stir welding. A surface of a connection portion of the end portion of the face plate 21 and the rib 24 is constituted by circular arcs 31 and 32 which are recessed in the hollow extruded frame member 20, and similar a surface of a connection portion of the end portion of the face plate 22 and the rib 24 is constituted by circular arcs 33 and 34. The diameter of the circular arcs 31,33 is smaller than the diameter of the circular arms 32,34. Accordingly, a structure body having a light weight can be obtained, which is able to absorb stress in the friction stir welding.

    Abstract: Two joined hollow frame members have face plates 11,12,21,22 connected in a truss manner by ribs 13A,13B,23A,23B. An end portion of one face plate 11,21 is positioned at the vicinity of an apex of the truss structure. An end portion 12b,22b of the other face plate projects further. The end portions 12b,22b are joined by friction stir joining from above. A connection member 30 is arranged between the upper face plates 11,21 and joined from above by friction stir joining. A load applied in the friction stir joining time is received by the ribs 13A,13B,23A,23B. A lightweight structure and high rigidity performance can be obtained.
