摘要： The purpose of the present invention is to provide a method that can be easily applied to friction stir welding where the thickness of face plates at one welding portion is different from the thickness of face plates at another welding portion. Three shape members 10, 11, 12 having two butt joint portions are mounted on a jig 15. The face plate 14 of shape member 10 is thick and the face plate 14 of shape member 12 is thin. The protruded height of projection 18 is greater at portion B where surface plates 14 being welded are thin than the protruded height of projection A where surface plates 14 are thick. The depths for inserting rotary tools to shape members 10, 11, 12 for friction stir welding are the same. Friction stir welding is facilitated since the size and insertion depth of all the rotary tools being applied can be the same.

摘要： 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 to be joined, at the joining region, thickened parts which project toward the rotary body joining tool 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.

摘要： A cutting tool 60 cuts along the butted portion between two members 10, 20. A filling material 30 is inserted to the gap 40 formed by said cutting, and a roller 70 presses protrusions 12 and 22 to crimp said protrusions 12 and 22 so as to fix said filling material to position. Next, friction stir welding is performed to the protrusions 12, 22 and the filling material 30 using a rotary tool 80. In another example, instead of cutting, the filling material can be welded and filled to the gap. In yet another example, cutting can be performed so as to approximate the two members before performing the friction stir welding step.

摘要： Grooves 18 formed to face plates 11 and 12 of a hollow shape member 10 at an abutted region with hollow shape member 20 receive projections 28 formed to face plates 21 and 22 of member 20. A connecting plate 14 orthogonal to the face plates 11 and 12 is provided to the hollow shape member 10. There is no connecting plate orthogonal to face plates 21 and 22 disposed on the end of the hollow shape member 20. Friction stir welding heat causes the face plate 21(22) to wove toward the thickness direction of hollow shape members 10 and 20, but such movement is suppressed by the groove 18 and projection 28. Thereby, the abutted region is welded flatly.

摘要： Abutted portions of face plates 12b and 22b of frame members 10 and 20 are friction stir welded. With the abutting, a projecting portion 20c of an end portion of the face plate 20b of the frame member 20 is inserted into a recessed portion 12c of an end portion of the face plate 12b of the frame member 10. By this engagement, the outer face on one face side of the face plates 12b and 20b form a smooth surface, so that there is no step at the joined edges. Next, a rotary tool 250 is inserted into the gap between the abutted plates, from the side of the raised portions 16 and 26 of the face plates 12b and 20b, while the other faces 12bc and 20bc of the face plates 12b and 20b are supported flatly on a bed during the friction stir welding. Accordingly, the welding of the engaged plates can be carried out without any step-wise difference.

摘要： A raised portion 32 is provided on an upper face of an end portion of a plate 31 which forms one side of a frame member 30. An end portion of a plate 41 of another frame member 40 is abutted with the plate 31 of the frame member 30. The frame members 30 and 40 are aluminum alloy extruded frame members and the directions of extrusion of the two frame members are orthogonal. A welding padding is carried on an upper face of the plate 41 of the frame member 40. Under this condition, a rotary tool is inserted from above and a friction stir welding is carried out. Accordingly, the padding serves the same function on the plate 41 as the raised portion 32 on the plate 31, so that a good welding can be carried out.

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： 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： A welding bead 50 is formed along to a jointing potion 40 using friction stir welding on a first frame member 20 and a second frame member 30, each of which is a hollow extruded molded base member made of an aluminum alloy A6N01 material. When a defect exists in this welding bead 50, the welding bead including this defect is moved by a grinding processing and then a mending zone is formed. In this mending zone, a mending bead is formed using TIG welding. The welding rod used in this TIG welding is made of the same material as the base member of the frame member, and so the composition of the welding bead is formed homogeneously. In the friction stir welding portion, a hairline processing is performed, so that a surface having a beautiful appearance, in which a boundary between the frame members and traces of the defect are inconspicuous, can be obtained. In a case of manufacture of a structural body, such as a railway car, in which an aluminum alloy material is subjected to a friction stir welding, an improvement of the method of mending the friction stir welding portion can be achieved.
