摘要
针对常规超声无损检测方法较难检测的奥氏体钢焊缝缺陷问题，将计算机技术、信号处理技术与超声检测技术相结合，研制成便携式超声波Ｐ扫描成象系统，该系统具有对缺陷分辨率高、定位精确、图象清晰和操作简便等优点，经现场实用表明，在石化、核电等领域有广泛的应用前景。
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.
