The process of hybrid laser-microplasma welding of sheet Ti–Al–V titanium alloy of TC4 grade (up to 3.0 mm) was studied. The recommended technological parameters and conditions of laser-microplasma welding in an argon medium, physical and mechanical properties of welded joints were determined, and the presence of hybrid effect was established. 5 Ref., 3 Tables, 7 Figures.
