The method for production of annular parts consists in separation from the bar of rectilinear billets and their bending into the rings with minimum manufacturing joint clearance, collection of the bent rings on the mandrel into the packet with orientation along the joint clearances with subsequent compression of the packet on this mandrel along theaxis. The places of common joint clearances are welded by a common weld, welded structure is removed from the mandrel, common welds from the outer sides are smoothed out, obtained ring-shaped billets are separated by a torque with respect to the axis, passing along the common weld and through the center of gravity of the cross section of this weld. Obtained ring-shaped billet is volumetrically deformed by manufacturing effort.
