The offered process of laser welding can be used at manufacture of cans, aerosol cylinder, at different tube making, etc. Distinctive feature of process is that welding is executed in the field of thickness with deep penetration, with subsequent rising of welded cylindrical preform in rolls up to necessary operational thickness. The laser welding in the field of thickness with deep penetration allows to avoid poor penetration, undercuts, burnouts, drop-shaped formations, significantl for laser welding of thin articles. Thus is improved the quality and reliability of the article. Final rising is carried out with rolls and mandrel and allows to use rotation of a tube around own axis simultaneously for several processes:forming of a tube, welding, final rising, cutting on parts.
