FIELD: metallurgy.
SUBSTANCE: invention can be used for production of filler materials for welding aluminium alloys, in particular welded structures from high-strength aluminium alloys of Al-Cu-Li. Filler material contains following component ratio, wt%: copper 5.0-12.0, zirconium 0.1-0.2, titanium 0.1-0.2, scandium 0.2-0.5, manganese 0.2-0.3, silver 0.6-1.0, neodymium 0.1-0.2, hafnium 0.1-0.4, cerium 0.05-0.15, dysprosium 0.1-0.2, yttrium 0.1-0.2, aluminium - balance.
EFFECT: technical result is reduced tendency to formation of hot cracks, high strength and impact strength of welded joints of high-strength aluminium alloys of Al-Cu-Li.
