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: A method of continuous welding of a series of tubes to a tube sheet, in which the torch current is decreased to produce partial fading of the arc after completion of the first welding bead, and the torch is then moved to a starting position on a second contour to be welded. A stationary preheat is then effected, and a second weld bead is made by following the second contour to be welded. The process continues until the last bead has been made, whereupon the arc is switched off.

Abstract: The replacement is carried out from an operating region located above the convex face (1a) of the head. The adaptor to be replaced is machined after removing its control mechanism (13) and a heat sleeve (4), by introducing suitable tooling (14) via the upper end of the adaptor (3') to be replaced. In succession, the lower part of the adaptor and a part of the weld of this adaptor are machined, a narrow chamfer is machined in the weld of the adaptor to be replaced, the remaining part of the adaptor (3') to be replaced is rebored inside the head (1), the adaptor is extracted, a replacement adaptor is fitted by cold binding (shrinking) and the replacement adaptor is welded.

Abstract: A jet of abrasive liquid is directed at high speed towards the surface of the element (13) with an angle of incidence lying between 30 and 90 DEG . The jet is moved so as to sweep the inner surface of the element (13). At least two successive machining passes are carried out. The speed of sweeping increases from one machining pass to the next. The device (30), mounted movably in translation and in rotation inside the adaptor (13), consists of a tubular assembly fed with pressurised liquid, on which a nozzle (33) is fixed.

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. … …
