nalysis upon Discontinuity Location Using Angle Beam Probe Ultrasonic Testing

When using ultrasonic testing instrument-Type HS616e-to detect the workpiece,the location of the discontinuity can be assured according to the echo infinity level on the screen.However,due to the spreading of the ultrasonic beam,the differences in the shape and orientation of the discontinuity always lead to the inaccurate loca- tion of the discontinuity,or even wrong judgment,ple is employed to innovate the locking structure and it has turned out to be effective in practical application.
