ABSTRACT:
An integral covered blading for a turbine is achieved by cutting a short arc cover spanning tips of multiple adjacent blades. Adjacent cover portions are formed for adjacent blades, each portion having facing sides. A material buildup between the facing sides of cover portions is effected and selective machining of the material buildup develops an interface between adjacent cover portions of adjacent blades. Short group blading is thereby converted to equivalent integral covered blading.
