FIELD: metallurgy.
SUBSTANCE: manufacturing method of solid constructional element welded by forging method from aluminium alloy involves hot pressure shaping stage, at least one cold pressure shaping stage by means of plastic deformation, at which at least two zones of the above constructional element are subject to average consolidated plastic deformations differing at least by 2% and preferably differing at least by 3%. If necessary, after cold pressure shaping there performed is cutting, machining and/or shaping of constructional element welded by means of forging method.
EFFECT: manufacture of constructional elements, including those not subject to tempering, having variable operating properties in the space and rather economic geometrical characteristics identical to characteristics of known elements.
