PROBLEM TO BE SOLVED: To provide a bonding method and a bonding structure according to rotary friction welding method which can be applied for bonding of a large scale object with a relatively small mechanism and preferably with a tool of a portable size.SOLUTION: A first object 1 and a second object 2 are arranged on positions which are adjacent to each other, and a void space 4 of a rotationally symmetrical shape spreading over the first object 1 and the second object 2 is processed. On the other hand, a bonding object 3 having a rotationally symmetrical shape nearly equal to the void space 4 of rotationally symmetrical shape is manufactured and is loosely fitted into the void space 4. Therein, a contact surface 5 between the first object 1 and the second object 2, and the bonding object 3 is constituted with a contact surface 5a between the first object 1 and a lateral circumferential surface 3a of the bonding object 3 and a contact surface 5b between the second object 2 and a lateral circumferential surface 3a of the bonding object 3. The bonding object 3 is rotated around a rotation shaft 6 of rotationally asymmetrical body while pressing the bonding object toward the contact surface 5 and material tissue in the neighborhood of the contact surface 5 is molten by utilizing friction generated on the contact surface 5 and is integrated. Thus, the first object 1 and the second object 2 are bonded via the bonding object 3.SELECTED DRAWING: Figure 1
【課題】比較的小さな機構で、好ましくは携帯可能なサイズの工具で、大規模な物体の接合に適用できる回転摩擦圧接法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の物体１と第２の物体２とを隣接した位置に配置すると共に第１の物体１と第２の物体２とに跨る回転対称形状の空所４を加工する。一方、回転対称形状の空所４と略同形状の回転対称形状を持つ接合物体３を製作し、空所４に遊嵌する。このとき、第１の物体１および第２の物体２と接合物体３との接触面５は、第１の物体１と接合物体３の側周面３ａとの接触面５ａと第２の物体２と接合物体３の側周面３ａとの接触面５ｂとで構成される。接合物体３を接触面５に向かって押圧しつつ回転対称体の回転軸６周りに回転させて、接触面５に生じる摩擦を利用し接触面５近傍の材料組織を溶融させ一体化させる。このようにして、接合物体３を介して第１の物体１と第２の物体２とを接合する。【選択図】図１
