Determination of Ultrasonic Testing Parameters for Welding Defects in Building Steel Structures and Their Impact on Welding Quality
This article mainly explores the determination method of various parameters for ultrasonic testing of steel structure weld quality,as well as the influence of weld defects on weld quality.The parameters that need to be determined mainly include defect echo acoustic path,surface coupling loss,defect equivalent and defect rate,etc.Based on this,ultrasonic testing is designed to test the influence of fusion butt weld defects on the tensile strength of the weld.The results indicate that,under the same experimental conditions,the smoothness of the inner wall of the weld and the location of the weld defect have an impact on the quality of the weld.
