Abstract
Non-destructive testing technology,with its advantages of non-destructiveness,efficiency,and sensitivity,has been widely applied in the field of construction engineering inspection.This article focuses on the applications of penetration testing,ultrasonic testing,and radiographic testing in detecting typical defects such as cracks in concrete structures and weld seams in steel structures.Through empirical research,the performance indicators of these three detection methods are systematically evaluated.The results indicate that radiographic testing outperforms ultrasonic testing and penetration testing in terms of defect detection rate,false alarm rate,missed detection rate,and accuracy,making it the preferred method in construction engineering inspection.The research findings provide important references for optimizing construction engineering inspection schemes and have certain engineering application value.关键词
