STUDY ON PORTABLE ULTRASONIC P-SCAN IMAGING SYSTEM

Abstract

Abstract: In view of the difficulty of conventional ultrasonic nondestructive testing (UNDT) method inspecting the defects in austenitic steel weld, the portable ultrasonic P-scan imaging system is developed by combining of computer, signal processing with UNDT. 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 system has the wide application prospects in petrochemical, nuclear plant and pressure vessel.

Key words: Austenite, Imaging, Ultrasonic, Weld
