Ultrasonic Testing Numerical Simulation of Austenitic Stainless Steel Pipeline Welding Cladding

Abstract:

In the paper, ultrasonic testing of austenitic stainless steel pipeline welding cladding is stimulated based on ultrasonic testing software CIVA. The result shows that the frequency is higher; the sensitivity on small defect testing is higher. When cylindrical defect with length of 6mm and diameter of 2mm is detected, the frequency is higher, the tested length-section result is more accurate, and the width-section (i.e., diameter) is not affected. The optimum frequency scope for testing the defect should be between 5MHz and 10MHz.
