Abstract: PURPOSE:To obtain a welding construction easily regardless of any increase in the slant angle of a diaphragm outer wheel side so as to improve its strength by applying edge preparation to the connecting portion of the diaphragm outer wheel side of a nozzle plate and applying direct fillet welding to the edge prepared portion and the diaphragm outer wheel. CONSTITUTION:A nozzle diaphragm has diaphragm outer wheel shapes 2A, 2B, stiffening metal angle 7, patch 9, diaphragm inner wheel shapes 4A, 4B and a welded portion 10. In this case, the method of welding the patch 9 to a nozzle plate 3 is the same as a conventional one, but welding the nozzle plate 3 to the diaphragm outer wheel 2A is directly achieved by fillet welded portion 12. That is, a spot facing portion 13 is provided on a cross section of the nozzle plate 3 to form a prepared edge and fillet welded portion 12 is provided on the diaphragm outer wheel 2A. Then, even if slant angle X deg. is increased, the nozzle plate 3 can be easily welded to the diaphragm outer wheel 2A. Therefore, the number of parts can be reduced without applying hole to the patch 9 with much time, and reliability can be increased.
