A method of grinding the tip of a blade which forms part of a rotor for a gas turbine engine is provided.

A weld repair method uses a gas tungsten or plasma arc welding torch and matching filler. An amperage supplied to the torch and a travel speed of the torch are controlled to produce a weld bead having a mushroom shape. The weld bead is ground from all sides to remove at least one half of a thickness of the weld bead, and another weld bead is formed.

A method of grinding the tip of a blade which forms part of a rotor for a gas turbine engine is provided.

Hydro-abrasive erosion in hydraulic turbines leads to reduced turbine efficiency and may entail cavitation. The splitter, responsible for smooth bifurcation of jet, located in the middle plane of each bucket is particularly relevant for turbine efficiency [].With reduced efficiency and eventual outages of HPPs, the electricity generation and revenues are reduced.

A turbine bucket consists of a leading edge, trailing edge, root portion, and tip portion. Turbine buckets also include cooling holes for cooling liquid running through the bucket. First stage buckets are the first surface that the gases from the first nozzle encounter.

Typical Turbine Hill Curve: Efficiency as a function of head and flow are summarized on a hill curve similar to the one shown above for Francis turbine operating limits are imposed by cavitation limits, maximum power and pressure surges. Proto type tests or model tests to determine turbine performance characteristics are discussed with special

The high pressure Turbine Blade machining processes utilize a wide range of manufacturing processes and a variety of machines.
