METHOD OF HYBRID LASER-ARC WELDING Russian patent published in 2017 - IPC B23K26/348 B23K28/02 B23K26/14 B23K9/173 B23K33/00

Abstract RU 2640105 C1

FIELD: technological processes.

SUBSTANCE: forming the weld pool by at the same time an electric arc and a laser beam by melting the metal of the filler material in a protective medium consisting of inert and active components. Argon is used as an inert component. The filler material is used in the form of two consumable wires with diameter up to 1.6 mm, which, together with a protective medium, are supplied from a single nozzle. Filling of the outer part of the cutting of edges is carried out by simultaneously melting the wires of a predetermined volume with the formation of an outer roller.

EFFECT: invention makes it possible to increase the productivity of the laser-hybrid welding process, reduce the defects in the formed weld, and improve its mechanical properties.
