1 results about "Axial data" patented technology

This invention belongs to the field of nondestructive testing and relates to an automatic evaluation method, system, and equipment for ultrasonic phased array testing of welded pipe end faces. It aims to solve the problems of high subjectivity, low efficiency, and lack of digital traceability in manual inspection of welded pipe ends. The invention includes: acquiring spectral data from two circumferential directions, one vertical wall thickness direction, and one axial detection direction, and selecting target image data from them. For circumferential data, longitudinal non-layered defects are evaluated based on whether the signal parameters exceed a first preset standard; for vertical wall thickness data, layered defects are evaluated based on whether the signal indication magnitude exceeds a second preset standard; for axial data, inherent structural echoes are intelligently identified and filtered out based on a three-dimensional model of the pipe end and a path-amplitude difference fusion algorithm, and transverse non-layered defects are evaluated based on whether the residual signal parameters exceed a third preset standard. This invention achieves automated and standardized detection and evaluation of welded pipe end defects, improving the objectivity, efficiency, and quality traceability of the inspection.
