Research on Fuzzy Comprehensive Evaluation of Ultrasonic Non-destructive Testing of Steel Structure Welds
Ultrasonic non-destructive testing is suitable for welding seam detection of various metal and non-metal materials,and is a widely used non-destructive testing method.At the same time,welding seam non-destructive testing has the characteristic of fuzzy uncertainty.In view of this,this article establishes a weld defect evaluation model based on fuzzy theory.Taking the welding seam detection project of a certain landscape engineering as an example,the feasibility of the model was verified by using fuzzy comprehensive discrimination results that match the actual discrimination results.The research results of this article have significant guiding significance for the detection of weld damage in steel structures.
