Abstract

Compositions of Al–Cu filler materials with additions of Sc, Hf, Nd, Ag to provide with improved resistance to hot cracking and mechanical properties of welding joints of high-strength aluminum-lithium alloys comparing with those obtained using the serial welding filler material SV-1201 are developed. It is shown that application of the developed filler materials is perspective for manufacturing welded structures and provides with increased operating reliability and durability.
