Abstract: Device for removing an electrode from an electrode holder and/or fitting an electrode into an electrode holder, said electrode holder forming part of a welding device, said device comprising a spent electrode receptacle provided with an orifice and an assembly mounted on said orifice, said assembly comprising a through passage with a longitudinal axis connecting a housing to hold one end of the electrode holder forming a mandrel, and the receptacle, said longitudinal axis being designed to be approximately vertical, means of tightening or loosening an electrode holder mandrel, means of fixing the electrode to said device and means of enabling or disabling dropping of the spent electrode into the receptacle.

Abstract: A device for changing the electrode of an electrode-holder tool of a welding device, with a first part configured to house an electrode-holder tool and including means to prevent the electrode-holder tool from moving, and a second part installed around the first part and covering the part of the electrode protruding outside the first part, where the second part can be separated from the first part by sliding along the electrode, and is able to rotate relative to the fixed part when it surrounds it, and where the second part is configured to tighten or untighten the mandrel and to attach the electrode and the second part, enabling it to be removed from the mandrel when the first part and the second part are separated.

Abstract: A spring mounting device in a cladding tube for nuclear fuel, comprising a spring distributor, a spring loader in the cladding tube, the distributor supplying the springs to the loader, said loader comprising a longitudinal slide to receive the spring, a pusher in order to set the spring into place in the cladding tube and is able to move in the slide, means of displacement of said pusher, said device comprising mechanical means in order to associate the actuation of the means of displacement with that of the spring distributor.

Abstract: Images of plant equipment are first acquired and then marked or tagged to provide reference images used during inspection of the plant equipment. The reference images provide easy guidance without requiring markers on the equipment. When inspecting fewer than all inspection points, an inspection route manager is used for selecting inspection points. A report generator provides a report with problem inspection points clearly indicated on images of the sites where problems are detected. GPS measurements of plant equipment positions are acquired when taking images, and are used to guide during general inspection and when visiting problem sites after general inspection.
