Abstract
Some peculiarities of formation of crater and weld pool in electron beam welding of 17 mm thick titanium alloy VT20 with complete and incomplete penetration in different positions are considered. Welding schematics and parameters providing defect-free formation of the face and reverse weld beads are given.
