Literature on fusion welding of titanium to steel by the electron beam and argon-arc tungsten-electrode methods is reviewed. It is shown that titanium cannot be directly joined to steel due to formation of brittle intermetallic phases. Therefore, the technology was suggested for joining these materials through intermediate barrier inserts. The use of intermediate inserts can be avoided by joining titanium to steel in a solid-liquid state. This joining is performed by projection resistance welding with programmed internal splashing and subsequent forging of the joining zone
Keywords: fusion welding, electron beam welding, argon-arc tungsten-electrode welding, projection resistance welding, solid-liquid state joining, titanium, steel, intermetallic phases, intermediate barrier inserts, vanadium carbides, titanium-steel interface
