Abstract
The control of the optical operation of a laser beam welding tool is carried out, when the tool is in an out of service position, by low-power auxiliary radiation. This radiation is passed to a measuring device (64) equipped with a photoelectric cell (86) after having traversed the tool as far as a welding head (58). The control can apply to an optical channel carried by a welding iron used for welding repair sleeves in pressurized water nuclear reactor steam generator tubes.
