| Abstract: | The results of investigations of the effect of the welding thermal cycle on the structure and properties of welded joints VT20 titanium alloy are presented. It is shown that the removal of capillary-condensed moisture from the surface of the welded components and degassing of the weld pool prevent the formation of pores and result in a large reduction of the mechanical properties of welded joints. |
