摘要： 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.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.

摘要： PROBLEM TO BE SOLVED: To provide a friction stir equipment capable of suppressing the unevenness of quality of an objective material, which is caused by the influence from disturbance such as an outside air temperature. SOLUTION: A controller 253 determines a rotation resistance force around an axis exerted to a rotary tool 30 from a material 33 to be joined, based on the value of current flowing to a servo motor for rotating the rotary tool 30, and determines, as a shoulder part contact time t2, the time when the rotating resistance force takes the maximum value. Then, a travelling start time t4 when the rotary tool 30 is made to travel from the material 33 to be joined is decided based on the shoulder part contact time t2. The state of friction stirring after the contact time t2 has passed is less influenced by the disturbance. Accordingly, by deciding the travelling start time t4 based on the contact time t2, the rotary tool 30 can be traveled in a fixed friction stirring state with the influence of disturbance suppressed, so that the quality of the material 33 to be joined is stabilized after joining.

摘要： PROBLEM TO BE SOLVED: To provide a structure reforming method which surely prevents the surface of a casting and a casting defect from being communicated with each other. SOLUTION: A rotary tool 20 having a base part 31, and a projecting part 32 extending by inclining from a front end 31a in an axial line direction of the base part 31 in a direction approaching a rear end 31b in the axial line direction as the projecting part protrudes in the radial direction of the base part 31 and progresses in one R1 of the peripheral direction around the rotary axis L1 is used to conduct friction stirring by rotating the rotary tool 20 in the one R1 of the peripheral direction. Thereby a fluid 38 with a softened part plastically flowing is formed in a prepared hole 36. The fluid 38 moves in the rotating direction R1 and also in the axial line direction Z1 and thereby the fluid 38 is made easier to stir and the amount of the fluid 38 plastically flowing can be increased. As a result, the fluid 38 can increase the solidified reforming layer 39 and can increase the amount of dissipation of the casting defects, and the inner peripheral surface of the prepared hole of the casting 19 is more surely prevented from being communicated with the casting defect.

摘要： PROBLEM TO BE SOLVED: To provide a joint structure of a hollow extruded shape which has suitable side edge profiles both for a face to apply a friction stirring and joining and for a face to apply a conventional build-up welding in order to solve the problem; when a hollow extruded shape for construction of a carriage structure of a train or the like is joined adopting a friction stirring and joining method, the method has been applied for both faces in the past so that after a first friction stirring and joining, a turnover and second friction stirring and joining is exerted, which requires much joining time occupying the joining equipment for long time.
SOLUTION: In the joint structure of the hollow extruded shape, a vertical rib 14, 14A is prepared on the side edge of at least one of the two hollow extruded shapes to be jointed together. For the section whose requirement of strength level after joining is low or whose necessity for the friction stirring and joining is low due to its shortness and etc. an arc welding joint such as for MIG and TIG is prepared installing welding grooves 24, 24A on a part or the whole of the face. This joining structure shortens the joining operation and can shorten the occupying time of the friction stirring and joining equipment.
