Digital image-forming tube bar material defect nondestructive flaw detection system

Abstract

Disclosed is a detection system for nondestructive flaw detection of digital imaging tube bars, which is characterized that: the detection system for nondestructive flaw detection of digital imaging tube bars comprises a table for workpiece to be detected (1), a loading conveyer table (2), a docking mechanism (3), a high-speed detecting table (4), a disengaging mechanism (5), an unloading conveyer table (6), a separating mechanism (7), a qualified workpiece storehouse (8), an unqualified workpiece storehouse (9), a water circulation system (10), a nondestructive testing instrument system (11) and an electric control system (12). The detection system has the advantages that the sizes and locations of defects can be displayed directly according to the detection records, the conclusion can be made by simple analysis and interpretation of the displayed graphics and data, the time needed for analysis is short, and the requirements to the technical level of analysts are not high.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, and in particular provides a non-destructive testing system for digital imaging tube bar defects. Background technique [0002] In order to ensure the safety of important facilities such as various equipment, mechanical structures, and pressure vessels, and prevent catastrophic accidents, people often first think of using non-destructive testing technology to check the materials or parts involved during the manufacturing process or during the manufacturing process. Non-destructive testing is carried out during use. Especially now that the concept of damage tolerance design is popular, it is even more necessary to know exactly whether there is a defect in the workpiece, the nature of the defect, the size of the defect and the location of the defect, so as to further evaluate whether the workpiece is qualified, how dangerous it is to use, or how long its service life is. how long. ...

Problems solved by technology

The first two can only detect defects, but cannot intuitively represent defects

In the third ultrasonic flaw detector or system, there are usually multiple detection channels, combined with the probe displacement scanning encoder and other means can realize B-scan (B-Scan) or C-scan (C-Scan) and S - Scanning (sector scanning S-Scan) and other display methods indicate the position and size of the defect, but it is difficult to intuitively express the severity of the defect, and the display method is still not intuitive enough. It is necessary to further analyze and interpret these display graphics and data before making a decision. in conclusion

The required analysis time is long and requires a high technical level of analysts
