The application of the ultrasonic phased array technology on T鄄weld shows its obvious advantages.
However, the beam areas of T鄄weld still can not be defined, and can not estimate the position of the echo. According
to the structure of the T鄄weld, the ultrasonic phased array inspection support software is compiled. Artificial sample
tests suggests that the computer鄄aided technology could achieve the beam coverage of T鄄welded and help to distinguish
the echo signal
