Abstract
The frame (9), which is positioned in relation to the tubular element (T), comprises disengagable means (40) for driving the working rod (18) in rotation, and these means can co-operate with at least two regions (26 to 28) of the rod. It is thus possible to work in a plurality of different zones of the tubular element. Application to the sleeve coupling by laser welding of the steam generator tubes of pressurized-water nuclear reactors.
