Method and apparatus for treating the internal surface of a gas bottle

摘要

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.
