Three-dimensional ultrasonic imaging non-destructive inspection system

Abstract

The three-dimensional ultrasonic imaging non-destructive inspection system is used in detecting, locating, quantifying and classifying faults inside industrial products including components and parts, and its measurement data may be exchanged with other system for searching cause of the faults and improving quality. Structurally, it has ultrasonic system, electromechanical executing system, A / D system, signal processing system, 3D display system, automatic control system and timing system installed on a computerized platform. During operation, the ultrasonic system sends out ultrasonic pulse to workpiece and receives the echo, the A / D system processes the echo signal and converts into digital signal fed to the computer, the signal processing system establishes the 3D data base of faults, and the 3D display system displays the 3D ultrasonic image with its 3D figure display software.

Description

(1) Technical field [0001] The invention relates to an ultrasonic imaging detection technology in the field of nondestructive flaw detection, in particular to a three-dimensional ultrasonic imaging nondestructive flaw detection system for detecting and monitoring internal defects of industrial equipment and product components. (2) Background technology [0002] At present, in my country, the detection of internal defects of industrial equipment and product parts is still generally performed manually (that is, the one-dimensional ultrasonic system), and it is impossible to talk about synchronous detection and monitoring with production. Some units have also developed the probe plane and rotary scanning flaw detection technology. Or helical scanning technology, some units use phased array technology for plane scanning, but these are only scanned images of a certain side, which are far from three-dimensional imaging, and complete post-processing of spatial...

[0002] At present, in my country, the detection of internal defects of industrial equipment and product parts is still generally performed manually (that is, the one-dimensional ultrasonic system), and it is impossible to talk about synchronous detection and monitoring with production. Some units have also developed the probe plane and rotary scanning flaw detection technology. Or helical scanning technology, some units use phased array technology for plane scanning, but these are only scanned images of a certain side, which are far from three-dimensional imaging, and complete post-processing of spatial information has not been realized, so it is difficult to ensure that information is not missing , no loss and correct judgment, let alone data exchange with other systems, to find out the cause of defects inside parts in time; on the other hand, medical three-dimensional ultrasonic imaging technology, such as patent No. 99125811.8, patent No. It is far from the detection target, acoustic characteristics and technical requirements of industrial non-destructive testing technology, so it cannot be transplanted
