    摘要： Installation for welding fuel assembly top nozzles onto nuclear fuel rods comprising a device (D) for axially retaining said rod and for setting it in rotation and a welding chamber (C), said device (D) comprising a gripper and means for closing the gripper onto the fuel rod, said means comprising a push-rod (32) to apply an axial force to the gripper, a linear actuator (44) of axis (X2) parallel to the longitudinal axis of the device (X), a yoke (46) translationally secured to said push-rod and able to rotate about a fixed axis (Y) orthogonal to the longitudinal axis (X) which is not secant therewith, said yoke (46) being articulated with respect to the linear actuator (44) about an axis (Y1) parallel to the orthogonal axis (Y) such that the linear actuator (44) causes the yoke (46) to rotate about the first orthogonal axis (Y) and causes a translational movement of the push-rod, closing the gripper onto the fuel rod.

    摘要： The invention relates to a device for changing an electrode of an electrode-carrying tool (2) of a welding device, said electrode-changing device comprising a first portion (12) for housing an electrode-carrying tool (2), said first portion (12) comprising a means for keeping the electrode-carrying tool (2) stationary and a second portion (14) that is mounted around the first portion (12) covering the portion of the electrode (8) that projects outside the first portion (12), the second portion (14) being separatable from the first portion (12) by means of translation along the electrode and being rotatably movable relative to the stationary portion (14) when said second portion surrounds said stationary portion, the second portion (14) comprising a means (33) for clamping onto or unclamping from the mandrel (6) and a means (36) for securing the electrode (8) of the second portion (14), thus enabling the removal of the mandrel (6) when the first portion (12) and second portion (14) separate.
