Abstract

A component inspection apparatus 100 and a method 200 for ultrasonic inspection of a component C, including low pressure last stage steam turbine blades, are disclosed. The apparatus 100 includes a guide member 110, a guide adapting member 120 and scanning probes 122. The guide member 110 includes a first surface 112 and a distal second surface 114. The first surface 112 is configured to adaptably mirror the shape of portions of the component C to be inspected. The guide adapting member 120 is capable of releasably attaching the second surface 114 of the guide member 110.to be changeable as per the shape of the component C. The scanning probes 122 may be located on the guide adapting member 120 in a manner configured to be movable along the second surface 114 of the guide member 110 to generate and receive ultrasonic waves used to inspect the component C.

Description

technical field [0001] The present disclosure relates to non-destructive material inspection, and more particularly to an apparatus and method for ultrasonic inspection of components, including but not limited to low pressure last stage steam turbine blades. Background technique [0002] Non-destructive material inspection using ultrasonic waves for detecting defects in components is generally known. [0003] In general, challenges exist when using ultrasonic techniques to inspect components such as airfoils, fillet radii, and particularly low pressure last stage steam turbine blades due to the different sizes, shapes and geometries and compactness of the components relative to each other. In general, for ultrasonic inspection of turbine blades, generally known special tools are available, of different shapes and designs, and including probes. These generally known tools are inserted between the blades for their inspection. The probe emits ultrasonic waves and receives ult...
