Research and Analysis of Process Technology for A-type Ultrasonic Testing of Area Type Defects in Butt Joints
Area type defects are defect types that appear as a two-dimensional shape in three-dimensional space as a whole.The stress at the end of an area type defect is highly concentrated and easily spreads forward.Area type defects are very dangerous and have a high degree of harm.The A-type ultrasonic testing technology of conventional non-destructive testing plays an important role in the quality inspection of butt welded joints.Ultrasonic testing has a high sensitivity for detecting area type defects.This article analyzes and studies the detection technology and process technology for typical area type defects such as lack of fusion and cracks.
