Abstract

The article presents the results of argon-arc welding technology of heat-resistant nickel, cobalt, and titanium based alloys, synthesized by selective laser melting. The study addresses similar and dissimilar joints of synthesized materials with wrought alloys used in manufacture and repair of hot-section components of PD series gas turbine engines. The welding parameters were optimized for KKh28M6, Kh15N5D4B, VT6-PS alloys as well as for dissimilar joints with steel 12Kh18N10T. The microstructure and mechanical properties after repair build-up welding were analyzed. The effect of thermal cycles on welds strength was established.
