25-56 STUDIU PRIVIND REPARAŢIA PRIN SUDARE A COMPONENTELOR DIN OŢEL MARTENSITIC ALE TURBINELOR HIDRAULICE
STUDY ON REPAIR BY WELDING MARTENSITIC STEEL
COMPONENTS OF HYDRAULIC TURBINES
CA-6NM cast parts are frequently used in the manufacture of rotors and
turbines guiding equipment. CA-6NM material behaves better at casting and
improved weld ability compared to the stainless steel CA-15. During the
production process, rotor blades or their repairs hydraulic power operation have
identified four situations. These four cases have resulted to the design of
different welding repair technologies that are intended to meet the specific
conditions of each case.
