FIELD: metallurgy.
SUBSTANCE: invention relates to production of sheet welded billet for hot forming. Billet includes a welded part formed by butt welding of first aluminium metal-coated steel sheet and second aluminium metal coated steel sheet. Welded part is produced in conditions that provide average concentration of aluminium in welding metal in welded part from 0.3 wt% to 1.5 wt%, and temperature point Ac3 of weld is 1,250 °C or lower.
EFFECT: providing required strength of connection after hot forming.
