FIELD: tube welding, namely, diffusion vacuum welding of lapped tubes from different materials. SUBSTANCE: welded zone of tubes 1,2 is placed into stationary annular support 3. Burnishing is realized by means of burnishing roller tool 6 having rod 5 secured eccentrically relative to rotation axis of burnishing tool 6. One burnishing roller 4 is mounted on rod 5 with possibility of rotation around its own axis. Method allows to join lapped tubes with minimum outer and inner diameters without heating bearing assembly supporting burnishing roller higher than 70 C. EFFECT: enhanced quality of tube joint. 3 cl, 2 dwg
