Benefits And Prospects Of Laser Welding Application In Vacuum

Abstract

In the recent years laser beam welding has been more and more broadly used in the industry for the production of details of significant appointment. One of the perspective directions of laser technologies for the production of significant products of big thickness is the welding by the concentrated laser beam in vacuum that allows producing faultless welded seams with the high relation of seam depth to its width. The conducted researches confirm results of theoretical modeling of processes at laser beam welding.
