FIELD: process engineering.
SUBSTANCE: method may be used for making critical welded structures in machine building. Parts of be welded are arranged with clearance. Adding material is fed into said clearance. Grooves and adding material are washed by electron beam and common molten pool is produced. Clearance width is selected proceeding from the condition 1.1d≤h≤1.2d, where h is clearance width and d is adding material diameter.
EFFECT: higher quality of welded joints.
