A TURBINE BLADE AND A METHOD OF MANUFACTURING AND REPAIRING A TURBINE BLADE

摘要

A turbine blade and a process for manufacture of turbine blades is provided comprising: casting as one piece a blade body and a first, portion of an airfoil; forming a tip section having a tip cap and a second portion of an airfoil which is sized to fit on the first portion of the airfoil; and attaching the first portion of the airfoil to the second portion of the airfoil. A process for repairing turbine blades is provided which comprises: removing the tip cap and a portion of the airfoil from the blade to form a repair surface on the airfoil; forming a replacement tip section comprising a replacement tip cap and a replacement portion of the airfoil sized to fit onto the repair surface; and attaching the replacement tip section to the repair surface.
