The influence of filler material on the properties and structure of joints of VT19 titanium pseudo-β-alloy, produced by tungsten electrode argon-arc welding was studied. It was established that predominantly β-phase in the amount of 60…77 % was present in the weld metal of all the joints of VT19 pseudo-β-alloy. Joints of VT19 alloy produced by argon-arc welding, using VT1-00sv filler wire in the amount of 20 %, have the tensile strength values at the level of 965 MPa, and exceed the base metal strength. To produce a homogeneous structure of the joints, it is necessary to use postweld annealing. The impact of annealing at the temperature of 760 °C results in formation in the metal of the joints produced by argon-arc welding of VT19 alloy, of a uniform, homogeneous, fi ne two-phase (α+β)-structure with values of tensile strength of welded joints on the level of 980 MPa.
