Abstract
Influence of structural condition of filler materials on the structure and properties of welds in welded joints of high-temperature titanium alloy VT8 is considered for the case of repair of aircraft engine parts. It is established that application of filler materials with submicrocrystalline structure allows ensuring an increase of the level of the joint mechanical properties.
