FIELD: process engineering.
SUBSTANCE: invention relates to laser welding of billets (9) from high-refractory super alloys. Heat laser source (3) creates generates zones (11) of heat feed to billet surface (10). Welding filler (13) is fed by device (5) to heat feed zone (11) and driven by transfer device (15) between heat source (3) and feed device (5) on one side and, on opposite side, and billet surface (10). Welding filler is fed at weight rate ≤350 mg/min.
EFFECT: set is one of the following laser welding parameters: laser power of 100 W to 300 W, laser beam diameter of 500 mcm to 800 mcm, welding rate of at least 250 mm/min.
