| Abstract: | in view of the difficulty of conventional ultrasonic nondestructive testing(UNDT) method inspecting the defects in austenitic steel weld, the portable ultrasonicP-scan imaging system is developed by combining of computer, signal processing withUNDT.This system has the advantages of high defect resolution, accurate positioning.clear image and easy operation. After the experiment of it in the field spot, this systemhas the wide application prospects in petrochemical, nuclear plant and pressure vessel. |
