The invention refers to the welding of the body and of the ring with the distributor of a steam turbine diaphragm. …<??>According to the invention the welding is carried out in four different areas holding an assembly (10), formed by two semi-diaphrams, in a substantially vertical position, at most tilted a few degrees off vertical, while four welding units (24) operate simultaneously, two for each face of the assembly, providing for each assembly face to be suitably heated. …<??>The apparatus is provided with two supports, one movable in respect to the other for positioning and handling of the assembly (10) to be treated, a means (28-31) for vertically adjusting the assembly position with respect to a referring surface, so that the area on which each welding unit works is always on the same level, whatever the dimensions of the assembly to be welded, and lastly heating and insulating means for both the assembly faces. |
