Abstract
Strength and fatigue characteristics of TIG and EB welded joints in experimental (a + b) titanium alloy T-110 of the Ti-Al-Mo-V-Nb-Fe-Zr system have been evaluated. TIG welding has been performed with an edge preparation and through penetration of plates with and without use of filler wire of the SP15 grade. Values of mechanical properties were compared with respective characteristics and also the life of welded joints of commercial alloy VT22.
Keywords: arc welding, electron beam welding, titanium alloy, welded joint, heat treatment, fatigue strength
