Investigations were performed of the metal of VT22 titanium alloy joints made by argon-arc surfacing with application
of an external magnetic field and metal-cored filler wire. Sound defectfree joints were produced as confirmed by gas
analysis and distribution of alloying elements in the deposited metal. Microstructural analysis showed that application of
an external magnetic field in argon-arc surfacing promotes formation of a more homogeneous and uniform structure of the
deposited metal that is also confirmed by quantitative analysis of phase distribution and analysis of intragraular structure
of the deposited metal. Microhardness and mechanical properties of the joints made by surfacing have also been studied.
