FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of parts from aluminum alloys and can be used for production of parts and assemblies of aviation and space-rocket systems. Production of parts by selective laser fusion is performed at the following processing parameters: laser power from 330 to 350 W, scanning speed from 900 to 930 mm/s, layer thickness of 50 mcm and scanning step of 0.19 mm.
EFFECT: obtaining parts with low porosity, high mechanical properties and low residual stresses.
