The method for treating the internal surface of a gas bottle includes the following steps: a) an incident laser treatment beam is introduced into a bottle through its mouth, approximately along the axis of the bottle; b) the laser beam is deflected in the bottle onto the internal surface of the bottle; c) a relative rotation between the bottle and the deflected laser beam is made approximately about the axis of the bottle; and d) a relative displacement between the bottle and the deflected laser beam is made so as to scan most of the internal surface of the bottle with the deflected laser beam. The apparatus for treating a bottle is designed to implement the steps of the method.
Method for treating the internal surface of a gas bottle, characterized in that it includes the following steps:
Method according to any one of the preceding claims, characterized in that the relative displacement comprises modifying the angle of deflection of the deflected laser beam with respect to the axis of the bottle.
Method according to any one of the preceding claims, characterized in that a cleaning gas is injected into the bottle during the scanning of its internal surface by the deflected laser beam.
Method according to any one of the preceding claims, characterized in that an amalgam of protective metals is projected onto the point of impact of the deflected laser beam on the bottle.
