Industrial X-ray flaw detection-based welding defect negative assessment method for teaching

Abstract

The invention specifically relates to an industrial X-ray flaw detection-based welding defect negative assessment method for teaching. The method comprises the following steps of automatically obtaining a welding negative numerical value; performing error analysis on a welding negative parameter; performing grade assessment on different types of welding defects; performing secondary operation grading on the welding negative numerical value; when different defect types exist in a single negative, outputting the grade of each defect; and if part of defect numerical values exceed a preset numerical value range, performing the fourth step of performing secondary operation grading on the defects. The single negative is subjected to comprehensive calculation grading; if the negative has the twotypes of the defects, the grade of the single negative is a grade obtained by subtracting 1 from the sum of the grades of the two defects after grading; if the negative has the three types of the defects, the grade of the single negative is a grade obtained by subtracting 2 from the sum of the grades of the three defects after grading; and a comprehensive calculation result is output. The method is simple and quick in calculation, thereby being suitable for use in daily teaching.

Description

technical field [0001] The invention relates to the field of flaw detectors for teaching, in particular to a method for evaluating welding defect films of industrial X-ray flaw detection for teaching. Background technique [0002] Industrial X-ray flaw detector is one of the most widely used industrial equipment in various industries at present, but due to its certain radiation, it is difficult for schools to use real equipment for teaching. And after using the X-ray flaw detector to carry out the flaw detection operation, it is necessary to grade the negative film. As a very important step, the negative film rating is very important, but it is currently in the state of manual evaluation, and its accuracy is poor and the speed is very slow. Contents of the invention [0003] 1. Technical problems to be solved: [0004] In view of the above existing problems, the present invention proposes a method for evaluating welding defect negatives for industrial X-ray flaw detection...
