In a method of preparing from weld material a component having a curvature which is symmetrical in rotation, difficulties arise, more particularly in the case of large and heavy components, in guiding the treatment zone. The treatment zone remains in a horizontal positio for welding, on stationary welding heads. For economic form welding under numerical control, it is proposed that the rotational axis of the component be tilted stepwise, to an extent depending upon the advance of the buildup of weld material layers, around a horizontal axis perpendicular to the rotational axis, the welding heads being adjusted stepwise as the tilt position varies.
