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 process comprises creating a heterogeneous weld (12) and applying a thick layer (14) of a nickel-based alloy to the inner surfaces of both pipe ends, extending axially along them, by means of a build-up weld. The thick layer covers the inner surface of the weld (12), protecting the bi-metallic joint between the two tubes.

Abstract: Using a robot arm (4), with a support (3) connected to an industrial installation, a succession of elementary tasks are carried out, each making use of a suitable tool (10). An index on the arm is used to determine the precise trajectories of the tools. The successive movements of the arm, the attachment and detachment of the tools and the carrying out of the tasks are controlled by suitable software modules.

Abstract: The procedure consists of fastening a tool support (36) by its locking mechanism (39') to the surface of the heating tube sleeve (3) so that its mobile section (42, 42', 45, 45') with coupling pins (43, 43') extends axially along the sleeve. A tubular support (37) is fitted round part of the heating tube (4) extending axially as far as a welding collar (7) by means of couplings (44, 44') attached to the pins, and an orbital welding machine (11) is fitted round the tubular support so that its torch (12) can rotate about the support's axis and follow the welding zone of the collar.

Abstract: The process comprises dismantling the part of the valve containing the shut-off element (8) and control mechanism (9) from the seat (4), and building up the worn seat ring (10) by plasma transfer arc (PTA) welding of a pre-alloyed metal powder, and then machining the metal deposit. The process, for use on a valve (3) in a fluid pipe (2), comprises dismantling the part of the valve containing the shut-off element (8) and control mechanism (9) from the seat (4), and building up the worn seat ring (10) by plasma transfer arc (PTA) welding of a pre-alloyed metal powder, and then machining the metal deposit. The build-up weld is made after machining away part of the worn seat ring and fitting weld supports round the valve seat to receive the new metal deposit, e.g. of Stellite, using a tungsten electrode and an inert gas.
