Numerical simulation of phased array ultrasonic testing for fillet weld defects of type-B sleeve
Type-B sleeve repair is one of the main permanent repair methods for long-distance oil and gas pipelines at present. However, fillet weld defects are often produced during the operation, which need to be detected and evaluated by phased array ultrasonic ...
