Abstract
(EN)
[Problem] To provide a welding method and a welding structure for welding steel members constituting a steel frame structure such as columns, beams, etc., of a construction steel structure, the welding method and welding structure operating by rotary friction that can be applied to welding of large-scale steel members, having a comparatively small mechanism, and in particular, using a simple mechanism involving only rotation without requiring a large pressing force. [Solution] A void 50 having a side peripheral surface 52 and a bottom part 51 is machined in a rotationally symmetrical shape spanning the end surface 11 of a first steel member 10 and the end surface 12 of a second steel member 20; in a state in which a pressing force is applied to a contact area 60 between the tip part 47 of a joining metal 40 and the bottom part 51 of the void 50, the joining metal 40 is rotated around a rotation axis 71 and friction is created; the material structure around a rotary friction surface 62 is welded using friction heat caused by the friction and molten metal 80 is generated; a gap 61 between a side peripheral surface 42 of the joining metal 40 and the side peripheral surface 52 of the void 50 is filled with the liquefied molten metal 80; and the first steel member 10 and the second steel member 20 are joined via the joining metal 40 through integration with the structure near the gap 61.

Le problème décrit par la présente invention est de fournir un procédé de soudage et une structure de soudage pour souder des éléments en acier constituant une structure de cadre en acier telle que des colonnes, des poutres, etc., d'une structure en acier de construction, le procédé de soudage et la structure de soudage fonctionnant par frottement rotatif pouvant être appliqué au soudage d'éléments en acier à grande échelle, ayant un mécanisme comparativement petit, et en particulier, à l'aide d'un mécanisme simple impliquant uniquement une rotation sans nécessiter une grande force de pression. La solution selon l'invention porte sur un vide 50 ayant une surface périphérique latérale 52 et une partie inférieure 51 qui est usiné dans une forme symétrique en rotation reliant la surface d'extrémité 11 d'un premier élément en acier 10 à la surface d'extrémité 12 d'un second élément en acier 20 ; dans un état dans lequel une force de pression est appliquée à une zone de contact 60 entre la partie pointe 47 d'un métal de jonction 40 et la partie inférieure 51 du vide 50, le métal de jonction 40 est mis en rotation autour d'un axe de rotation 71 et un frottement est créé ; la structure de matériau autour d'une surface de frottement rotatif est soudée à l'aide d'une chaleur de frottement provoquée par le frottement et un métal fondu est généré ; un espace 61 entre une surface périphérique latérale 42 du métal de jonction 40 et la surface périphérique latérale 52 du vide 50 est rempli avec le métal fondu liquéfié 80 ; et le premier élément en acier 10 et le second élément en acier 20 sont reliés par l'intermédiaire du métal de jonction 40 par intégration avec la structure à proximité de l'espace 61.

【課題】建築鋼構造の柱や梁などの鋼構造骨組を構成する鋼材の接合のため、比較的小さな機構で、特に、大きな押し付け力を必要とせず回転のみの簡易な機構を用いて、大規模な鋼材の接合に適用できる回転摩擦による接合方法および接合構造を提供する。 【解決手段】第1の鋼材10の端面11と第2の鋼材20の端面12とに跨り回転対称形状で側周面52と底部51を有する空所50を加工し、接合金属40の先端部47と空所50の底部51との接触部60に押圧力を加えた状態で接合金属40を回転軸71周りに回転させて摩擦を生ぜしめ、摩擦による摩擦熱を利用して回転摩擦面62近傍の材料組織を溶融させて溶融金属80を生成し、液体化した溶融金属80を接合金属40の側周面42と空所50の側周面52との隙間61に充填させ、隙間61近傍の組織と一体化させることにより接合金属40を介して第1の鋼材10と第2の鋼材20とを接合する。
