- Abstract
At present time, welding of high-strength titanium alloys can be performed using arc, electron beam in vacuum (EBW) and laser beam. There are successful examples of application of combined laser-arc process for performance of welded joints of titanium alloys. Negative effect of thermal cycle of EBW and laser welding on properties of series of alloyed titanium alloys is indicated in some cases. Aim of the present work lied in investigation of effect of different methods of welding and filler metal on mechanical properties and structure of welded joints by the example of titanium alloy T110. It is shown that high-strength titanium alloy T110 differs in good weldability in performance welded joints by EBW, full penetration argon-arc tungsten-electrode welding, argon-arc tungsten-electrode welding over the flux layer and laser-arc welding. SP-15 grade wire is reasonable for application as filler for argon-arc welding of T110 alloy. If welding without filler material is used, argon-arc tungsten-electrode welding over the flux layer provides the highest values of impact toughness of weld and HAZ metal.
