LASER WELDING SYSTEM AND WELDING METHOD USING LASER BEAM

摘要

FIELD: physics.SUBSTANCE: system comprises a laser beam source (1), a laser beam collimator (2) and a focusing device (3). An optical element (5) is placed between the collimator and the focusing device (3) and is designed to branch the system for distributing the laser beam power in a first direction at an angle to the axis of the collimated laser beam. In the system according to a first version, a bifocal element (6) is placed either between the optical element (5) and the collimator (2) or between the optical element (5) and the focusing device (3). In a second version, a bifocal element (6) is placed between the collimator (2) and the focusing device (3).EFFECT: homogeneity of power distribution of laser radiation in the welded area.22 cl, 9 dwg
