摘要： A hollow frame member is constituted by two face plates 11, 12 (21, 22) joined in a truss shape by ribs. End portions of one of the face plates are positioned in the vicinity of an apex of the truss structure of the hollow frame member. End portions of the other of the face plates have a projection extending toward the end portions of the face plates. The face plates are joined by friction stir welding. Due to the presence of the ribs, the load during the friction stir welding time is easily supported.

摘要： End portions of extruded frame members 50 and 60 have increased thickness portions 56 and 66 which project toward an outer side thereof. A rotary body 70 is inserted into the increased thickness portions 56 and 66 and is rotated so as to carry out friction stir welding of the frame members. A large diameter portion 71 of the rotary body 70 is inserted to a position between the apex of the increased thickness portion and an extension line of an outer face of the plates 51 and 61 of the extruded frame members 50 and 60 as the rotary body 70 is rotated. Further, the rotary body 70 is reciprocated in a direction orthogonal to the welding line as it is moved along the welding line. Accordingly, friction stir welding can be carried out fully. In the friction stir welding, due to a rotation of the rotary body 70, even when a gap g between two extruded frame members to be subjected to welding is large, it is possible to carry out the friction stir welding.

摘要： A hollow frame member is constituted by two face plates 11, 12 (21, 22) joined in a truss shape by ribs 13, 13A, 13B (23, 23A, 23B). End portions of one of the face plates 11 and 21 are positioned in the vicinity of an apex of the truss structure of the hollow frame member. End portions of the other of the face plates 12b and 22b have a projection extending toward the end portions of the face plates 11 and 21. The face plates 12b and 22b are joined by friction stir welding from an upper portion. Next, a connection member 30 is arranged between the ends of the face plates 11 and 21, and from an upper portion the friction stir welding is again carried out. Due to the presence of the ribs 13A, 13B (23A, 23B), the load during the friction stir welding time is easily supported. Since the truss structure is formed totally, a light weight structure with a high rigidity performance can be obtained.

摘要： In a case where a welding of a member is performed through a friction stir welding, to restrain the generation of a clearance in a portion to be joined by the welding and to provide a joint having a good joining portion, abutting faces of members are formed with slanting surfaces. A friction stir welding is carried out from an upper portion. The welding is carried out with the slanting surfaces resisting the forces produced in forming the welding bead. Since the slanting surfaces are provided, a flow-out of the material in the welding bead can be restrained, and further a bending of the joining portion can be restrained. Further, a tab is arranged at a beginning end and a finish end of the welding and then the welding is carried out starting at one tab and ending at the other tab.

摘要： When an insertion force of a rotary tool 340 has searched, it is made clearly that the force at the insertion initial time is large and when a friction stir joining is an ordinary operation time, the force becomes small. According, it is preferable to make small the insertion force at the insertion initial time. To members 20, 30 to be subjected to a joining at a position where the friction stir joining starts a hole 50 is opened, and this hole 50 after the rotary tool 340 has inserted, since a move of the rotary tool 340 is made to begin, a lowering of the insertion force can be attained.

摘要： End portions of face plates 111 and 112 of a frame member 110 are connected by a rib 116A. To protrusion chips 117b1 and 117b2 end portions of face plates 101 and 102 of another frame member 100 are overlapped. The corners between the rib 116A and the rear face of the face plates 111 and 112 are in the form of the corners circular arc 131 which protrudes into a hollow portion 119 of the frame member 110. Both end portions of the circular arc 131b1 are connected to the rib 116A and the face plates 111 and 112 by two smooth recessed circular arcs 132b1 and 133b1. Accordingly, since a flow-out of metal does not occur from this portion, the cross-section can be small and a light weight structure can be obtained. A structural body formed of hollow frame members which are joined by friction stir welding provides a light weight structure.
