The paper considers an approach for selection of filler material in TIG welding of VT22 titanium alloy. It is shown that weld metal produced using pilot flux-cored wire PPT-22 is a representative of transient class of titanium alloys, to which VT22 alloy is referred (coefficient of β-stabilizing of such metal equals to 1). This wire can be used for argon-arc welding of high-strength VT22 titanium alloys. Mechanical properties of such welded joints after heat treatment reach the level of base metal indices. Application of PPT-22 wire in restoration argon-arc surfacing of VT22 alloy parts provides their high service characteristics. 15 Ref., 4 Tables, 5 Figures.
Keywords: VT22 titanium alloy, flux-cored wire, TIG welding, restoration surfacing
