METHOD OF LASER ELECTROSLAG WELDING Russian patent published in 2012 - IPC B23K28/02 B23K25/00 B23K26/00 

FIELD: process engineering.

SUBSTANCE: proposed method relates to hydride method of laser welding, particularly, to laser electroslag welding to be used in machine building for producing welded structures at larger thickness of welded edges. Slag and metal baths are formed. Said baths are retained in space limited by copper shaping plates and weld seam edges. Slag, filler wire or consumable plate electrode, seam metal or edges are heated by heat released by electric current passing between electrodes and seam metal and through fused slag. Laser beam is fed onto slag bath surface, its power being uniformly distributed over welding bath mirror surface and filler wire of consumable electrode feed rate being simultaneously increased.

EFFECT: higher efficiency.
