Abstract��The automated ultrasonic testing (AUT) for the weld bead of longitudinal submerged arc welding (SAWL) pipe were researched systematically by analysis of present situation. It��s certain that AUT for the weld bead of SAWL pipe can be fully achieved by means of partition testing. Research mainly includes the following aspects�� such as probe arrangement and assign�� alarm gate setting�� reference tube design�� reference artifical defects choice�� testing result display and record�� etc. The research results provide a reference for the method of AUT for the weld bead of SAWL pipe�� and also give some basis for formulating the standard of the method of AUT for the weld bead of SAWL pipe.
