Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
On the questions that the area to detect is big and the examination environment is wicked for the pressure vessel and other large-scale equipment welded joint, proposed an examination method by using acoustic emission diagnosis technology to monitor crack´s sketchy position, then again using the ultrasonic testing to determinate crack´s accurate position, the size and the shape, discussed in detail the technique that has used the correlation function principle processing detection signal, obtained the time difference between sensors that sound signal transmit from the crack to sensors by using correlation instrument processing, and established the position of a crack according to the designed data processing model, finally has confirmed the method feasibility through the examination application.
