Multi-view ultrasonic flaw detection system and detection method for steel rail weld joints

Abstract

The invention aims at providing a multi-view ultrasonic flaw detection system and a detection method for steel rail weld joints. The multi-view ultrasonic flaw detection system specifically comprises a scanning system, an ultrasonic system and an imaging system, wherein the scanning system is connected with the ultrasonic system to form an ultrasonic scanning system; the imaging system comprises a host, an IO control panel, a power module and a display module; the host is connected with the IO control panel and the display module; the power module is used for supplying power for the imaging system; the host is connected with the ultrasonic system. The multi-view ultrasonic flaw detection system has a perfect file management function, is capable of satisfying the functions of data detection, image storage, image retrieval, image copying, image analysis and the like, has a warning function, is capable of helping the users to find the defects preferably, has adaptability and is capable of adapting to different rail types on the scenes.

Description

technical field [0001] The invention belongs to the technical field of nondestructive testing, and in particular relates to an ultrasonic imaging detection and multi-view imaging method for railway rail weld seams. Background technique [0002] The ultrasonic flaw detection method of railway rail welds is used for the detection of welds at rail joints, and there is a joint weld every 25 meters of rails. Rail weld flaw detection has always been a difficult point in railway inspection. At present, there is no recognized good method at home and abroad. In the domestic engineering department, a large-angle single crystal probe is mainly used to scan the rail head and rail foot slope using A-type ultrasound. This method of flaw detection relies heavily on the operation of flaw detectors, which is inefficient and prone to false detection and missed detection. [0003] As an important part of non-destructive testing technology, the application of ultrasonic testing technology in m...
