A method of surfacing bodies of revolution consists in surfacing along a helix and accompanying heating. The accompanying heating begins at an area diametrically opposite to the beginning of surfacing, a source of accompanying heating is moved in the direction of welding and heating is stopped after passage by the heat source of area L equal to L=20.35*a*D/Vh*H. Then forced cooling of the weld metal is performed, which occurs in the temperature range of 1100-.
