FIELD: process engineering.
SUBSTANCE: invention relates to welding. Butt of blanks 1 and 2 is arranged at support roller 5 with form chase 4. Weld is produced by displacing working rod 6 of welding tool 7 to make weld root. Adding material 3 following the shape of roller 5 form chase 4 is continuously fed into said form chase. End of welding tool rod 6 is displaced during welding into adding material 3. Note here that edges of parts 1 and 2 and those of adding material 3 are squeezed by welding tool 7 in welding zone.
EFFECT: complete penetration of blanks over depth, higher quality of weld.
