- the upper end face 112a 2 which faces the bottom surface 116a and bottom surface 116a corresponds to the "separation plane" in the claims.
- the first member 102 is fixed and the second member 103 is relatively moved. Therefore, in the butting process, the periphery of the first side wall portion 112 of the first member 102 is fixed by a fixing jig. Restrained to move.
- the friction welding process is a process of joining the first member 102 and the second member 103 by performing a friction process and a pressure welding process.
- the friction step the abutted first member 102 and second member 103 are pressed in a direction approaching each other. Then, the second member 103 is rotated in the circumferential direction around the axial center of the first member 102.
- burrs are generated when the softened base material is pushed out to the inside and outside of the joint.
- the distance between the upper end face 112a 2 and the bottom surface 116a is approximately half before friction welding. Burrs generated in the outer, upper end face 112a 2, is accommodated in a space surrounded by the bottom surface 116a and side 116 b.
- the welding process is substantially equivalent to the first embodiment.
- first member 102 and the second member 103 have a cylindrical shape as in the present embodiment, the same effect as that of the first embodiment can be obtained.
- cylindrical members were joined, it is not limited to this. It is sufficient that at least one of the members to be joined is cylindrical.
- a bottom portion may be provided on either the first member or the second member to form a bottomed cylindrical member or a hollow cylindrical member.
- you may join a solid 1st member and a 2nd member.
- the present invention can also be applied when joining cylinders.
- the portion of the first member where the second member abuts has a frame shape in plan view means that the second member of the first member abuts.
- the shape of the portion when viewed in plan includes other polygonal frame shapes such as a cylindrical shape, a triangular frame shape, a rectangular frame shape, and a hexagonal frame shape.

Abstract
Description
本発明の第一実施形態に係る部材の接合方法について図面を参照して詳細に説明する。図1に示すように、本実施形態の部材の接合方法では、金属部材同士を接合して中空容器1を製造する場合を例示する。中空容器1は、例えば、内部に流体を流して伝熱部材として用いられる。説明における「前後」、「左右」、「上下」は図1の矢印に従う(第一部材2を基準とする)。
なお、溶接工程の際には、底面26aに平行で、かつ、溶接の中心線V1とバリSの先端とが重なるように設定してもよい。また、底面26aに平行で、かつ、溶接の中心線V1が、上端面14a2と底面26aとの間の中点を通るように設定してもよい。バリSの発生形態に応じて溶接の中心線V1を適宜設定することで、仕上がり面をきれいにすることができる。
図6の(a)に示す第一変形例は、突合せ部J1の内側にも離間面を設けた点で第一実施形態と相違する。第一変形例では、第一実施形態と相違する点を中心に説明する。
図6の(b)に示す第二変形例は、第一部材2Bにも切欠き部16を設けた点で第一実施形態と相違する。第二変形例では、第一実施形態との相違点を中心に説明する。
図7に示す第三変形例は、第二部材3Cに面取り部26Cを設けた点で第一実施形態と相違する。第三変形例では、第一実施形態との相違点を中心に説明する。
