The process of hybrid laser-micro-plasma welding of thin-sheet Ti-Al-V titanium alloy of TS4 grade (up to 3.0 mm) was investigated. The recommended technological parameters and conditions of laser-plasma welding in argon medium, physical and mechanical properties of welded joints were determined, and the presence of hybrid effect was established. 5 Ref., 3 Tabl., 7 Fig.
