Abstract
An ultrasonic phased array transducer assembly having a single housing in which a plurality of phased array transducer subassemblies are mounted at a skewed angle relative to a leading face of the housing and to each other, with each transducer mounted on composite wedge(s) at different orientations within the housing.
Claims18
A method of inspecting welds of a pipe in a boiling water nuclear reactor using a phased array transducer assembly, the method comprising:
- positioning the phased array transducer assembly adjacent to a surface of the pipe such that a face of a housing of the phased array transducer assembly is positioned adjacent to a weld to be inspected;
- generating an ultrasonic beam using a phased array subassembly that is mounted on a wedge of the phased array transducer assembly and oriented at a first angle relative to the face of the housing of the phased array transducer assembly, wherein the wedge is positioned within an internal cavity of the housing of the phased array transducer assembly;
- and
- scanning the pipe, such that a range of the ultrasonic beam comprises an area encompassing the weld of the pipe.
A method of inspecting welds of a pipe in a boiling water nuclear reactor using a phased array transducer assembly, the method comprising:
- positioning the phased array transducer assembly adjacent to a surface of the pipe such that a face of a housing of the phased array transducer assembly is positioned adjacent to a weld to be inspected;
- generating an ultrasonic beam using a first phased array subassembly, a second phase array subassembly, and a third phase array subassembly, wherein the first phased array subassembly is mounted on a first wedge, wherein the second phased array subassembly is mounted on a second wedge, and wherein the third phased array subassembly is mounted on a third wedge;
- and
- scanning the pipe, such that a range of the ultrasonic beam comprises an area encompassing the weld of the pipe.
