Selection of Technological Parameters for Phased Array Ultrasonic Testing of Weld

This paper indicated the advantage and disadvantage of traditional testing for weld inspection, and showed the benefit of using ultrasonic phased array instead of RT, but this should be based on the correct parameter setting up. The content introduces the system of phased array ultrasonic testing and its parameters & essential variable,and it is important to select these parameters as they may affect the test result.
