Abstract
The head (1) for laser working in centered in the tube (2) by two open circular brushes. The laser working is performed under the protection of a primary gas emerging through the window (5) for passage of the laser beam and of a secondary gas circulating axially between the head and the tube (2). The invention is used in the socket fitting of the tubes of the steam generators of pressurized-water nuclear reactors.
