Abstract
Analysis of different variants of existing designs of a barrel for the laser welding is given. Results on improvement of the protection of a focusing lens in CO2-laser welding of aluminium alloys from sprays of metal vapours and its heating by the reflected beams are presented. New design solutions on manufacture of the barrel are offered taking into account the conditions of the laser welding of aluminium alloys.
Keywords: laser welding, aluminium alloys, reflected beams, barrel, lens, plasma flame
