    摘要： The seam welding apparatus welds a workpiece held by a robot while delivering the workpiece between a pair of electrode rolls. The seam welding apparatus includes a load cell mounted on the robot, for detecting a load imposed along a Y direction which is perpendicular to a pressing direction Z along which the electrode rolls press the workpiece at a weld point and a delivering direction X along which the robot delivers the workpiece at the weld point, a robot controller and an arithmetic unit, a turning mechanism for turning the electrode rolls about the pressing direction Z, and a control device for controlling the turning mechanism to operate depending on the magnitude of the load in the Y direction detected by the load cell.

    摘要： A method of manufacturing a cylindrical body, comprising the step of forming the cylindrical body by bending a plate-like work having first projected finger to fourth projected finger at four corned parts and allowing the end faces thereof to abut on each other, wherein the main surface of the cylindrical body on the side where sags are present is formed in an outer peripheral wall surface and the rear surface thereof on the side where the burrs are present is formed in an inner peripheral wall surface, and a first projected part is formed of the first projected finger and the third projected finger and a second projected part is formed of the second projected finger and the fourth projected finger. After the cylindrical body is held by friction stir welding devices, the probe of a friction stir welding tool is buried from the direction of either of the first projected part and the second projected part, and scanned in the direction of the other of the second projected part and the first projected part. The probe is buried and scanned in the state of being displaced to an advancing side.

    摘要： A friction stir welding apparatus (120) brings end faces (1, 2) of a plate material (W1), having fingers (7a through 7d) at corners thereof, into abutment against each other to form a hollow cylindrical body (W2), and friction-stir-welds the end faces (1, 2) to each other. The apparatus includes a base (122), a first support device and second support device which are mounted on the base (122), a support core (32) spaced from the base (122) by the first support device and the second support device, for insertion into the hollow cylindrical body (W2) and for supporting the hollow cylindrical body (W2), and a first gripping member (238) and a second gripping member (268) disposed on the support core (32) for gripping respective protrusions (8, 9), which are formed when the fingers (7a through 7d) are held in abutment against opposite ends of abutting regions of the hollow cylindrical body (W2), and which extend along a joining direction. The support core (32) has passages (258, 260) defined therein for passage of a cooling medium therethrough.
