Abstract: An adapter (1), which passes through an aperture (3) in the cover (4) of a nuclear reactor vessel, is repaired by cutting through the welded joint (7) between the adapter coupling (6) and sleeve (2), machining a chamfered edge on the upper end of the sleeve, applying a new adapter with a chamfered coupling edge, and re-welding the components together by filling the chamfers with metal. The position of the adapter is monitored before and after welding.

Abstract: The welding electrode (21) moves rotationally about the axis (23) of the cylindrical piece, so as to lay down, one on the other, layers each covering the entire width of the bevel (16). The speed of rotation of the electrode (21) about the axis (23) of the cylindrical piece (14) is varied and the electrode (21) is moved translationally along the direction of the axis of the cylindrical piece. The device includes means for adjusting the speed of rotation of the electrode (21) and means for moving the electrode along the direction of the axis (23). The process may be used in particular to weld a replacement adaptor (14) to the head of the vessel (1) of a nuclear reactor.

Abstract: The removable platform comprises a chute (14) comprising a handling and fastening unit (18, 19, 14a) at one of its ends and a supporting part (14b) in the shape of a laterally open cylindrical part extending the shell (14a) substantially in its axial direction, a supporting shaft (16) mounted articulated at the end of the chute, a set of supporting arms (15) mounted on the support shaft (16) so as to pivot around the axis (29) of the supporting shaft (16) and a plurality of flat components (17) intended to rest on the supporting arms (15) in deployed position to form a working platform substantially over the whole cross-section of the enclosure (2). The removable platform is introduced into the enclosure (2) in the folded state; the arms (15) form a set (30) housed in the chute (17) and the supporting shaft (16) has its axis (29') substantially perpendicular to the lengthwise direction of the chute (14). The supporting shaft (16) and the arms (15) are then swung down so that the axis (29) of the supporting shaft (16) coincides with the axis (20) of the enclosure (2). The arms (15) are then deployed by pivoting about the axis (29) of the supporting shaft (16) and the flat components (17) are placed on the supporting arms (15) in deployed position. … …

Abstract: Method of making a great number of weld beads in the form of independent contours spaced apart by means of an automatic welding head comprising a torch and means for displacing the torch in several directions allowing the latter to follow each contour one after the other. The method is characterized by the fact that after striking of the arc and positioning of the torch on the first contour to be welded and then making of the first weld bead have been effected in a known way, the torch current is decreased to effect a partial fading out of the arc. A displacement of the torch is then effected as far as a starting position on a second contour to be welded, and a timed stationary preheat is effected at this point by controlling the return to welding current. The second weld bead is made by following the second contour to be welded, the torch current is then decreased to obtain a further partial fading out of the arc, and a further displacement of the torch is effected as far as a starting point on a third contour to be welded. The third contour is then done and so on, transfer from one contour to the other and adjustment of welding parameters is effected automatically until the last bead is made. The arc is then switched off.

Abstract: A surfacing plate for a boring and milling machine comprising a hollow cylindrical body provided with a rear end fixed to the milling spindle and a head on which a radial guide is formed for a tool holder slide. The movement of the slide is controlled by the boring spindle through a control unit located inside the body and comprising a central part sliding longitudinally in the body under the action of the spindle and having two longitudinal racks. The slide bears two radial racks connected respectively to the two longitudinal racks through two independant transmission trains, and is provided with means for adjusting the relative radial position of the two radial racks for taking up the play in the transmission.
