<P>PROBLEM TO BE SOLVED: To provide a joining method and a joining apparatus which can join a junction member to a member to be joined with a slight press force with high reliability without detriment to working environment. <P>SOLUTION: In the joining method, a member of lowering a melting point is placed between a stud 2 and a workpiece 3. The member of lowering the melting point is composed of a metal material capable of eutectic reaction with the metal material constructing the stud 2 and the workpiece 3. The stud 2 is rotated to generate friction heat while the stud 2 is pressed against the workpiece 3 via the material of lowering the melting point inserted therebetween. Taking advantage of eutectic reaction, the connection portions of the stud 2 and the workpiece 3 and the member of lowering the melting point are melted. Then, the rotation of the stud 2 is stopped and the stud 2 is joined to the workpiece 3. Thus, the junction member can be joined to the member to be joined with a slight press force with high reliability without detriment to working environment. <P>COPYRIGHT: (C)2012,JPO&INPIT |
