Abstract
The butt welded joints of 30-mm plates made of titanium alloy VT6ch obtained by electron-beam welding are studied. The mechanical properties of the base metal and welded joints are determined. Plastic deformation in the broken welded samples is localized in the base metal at a distance from the weld which is characterized by a decrease in the value of the relative uniform elongation (stretch ratio) in the weld zone compared to the zone of base metal. Special specimens with a reduced working part have been developed to study the mechanical properties of the weld metal both along and perpendicular to the weld direction. The strength characteristics of the weld metal in both directions exceed the corresponding characteristics of the base metal while the plastic characteristics of the weld metal are lower than that of the base metal. The obtained results match the available literature data.
