The method for manufacturing a rotor (1) by welding or brazing a plurality of elements (2) together comprises vertically staking the elements (2) to form a pile (3), partially welding or brazing adjacent elements (2) with the pile (3) in the vertical configuration, bringing the pile (3) to an horizontal configuration, completely welding or brazing adjacent elements (2) with the pile (3) in the horizontal configuration. Then, the method includes defining at least a parameter indicative of at least the stress and/or deformation of the pile (3), providing a desired parameter value or range during welding or brazing of selected adjacent elements with the pile (3) in the vertical and/or horizontal configuration, and supporting the pile (3) to maintain the parameter at the desired parameter value or within the desired parameter range.
