摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a sputtering target and a thin cooling plate which has a large-area shape, high cooling efficiency and a small thermal strain. SOLUTION: The cooling plate is characterized as follows: a groove 4 serving as a passage for a refrigerant is provided inside a main body 1 and covered with a cover 2 which is wider than the groove 4; the cover 2 is joined to the main body 1 by friction stir welding; and a joining bead is formed inside the main body 1 by the friction stir welding. In the cooling plate, the inside of the main body is provided with the first groove which serves as the passage for the refrigerant and the second groove which is wider than the first groove and makes the cover placed on the first groove, and the cover is placed on the second groove and joined to the main body 1. The manufacturing method for the cooling plate is characterized in that the cover and the main body 1 are joined together by the friction stir welding, which is performed by insertion of a rotating tool 6 having a shoulder 7 and a pin 8, so that the joining bead formed by the friction stir welding can be located outside the passage.

摘要： It is an object of the present invention to provide a friction stir welding method and apparatus capable of maintaining a rotating tool and workpieces at a substantially constant geometrical relation for arbitrary curved surfaces having a three-dimensional shape, as well as a welded structure obtained thereby. The present invention resides in a friction stir welding method comprising joining workpieces while setting rotational angles of two rotational axes of a rotating tool (11) which the two rotational axes are rotatable in intersecting directions or perpendicularly intersecting directions independently of rotation of the rotating tool, detecting a normal line direction with respect to joint surfaces of the workpieces and a tangential direction of a joint line, and joining the workpieces in three-dimensional directions while setting, on the basis of the detected normal line direction and tangential direction, an angle relative to a normal line direction, as well as a tangential direction, at a tip end of the rotating tool, and also resides in a friction stir welding apparatus using the said method.
