摘要
将计算机技术、信号处理技术与超声检测技术结合起来,研制成功检验奥氏体钢焊缝便携式超声波P扫描成象仪,该仪器具有缺陷分辨力高、定位精确、图象清晰及操作简便等优点。燕山石化现场试验表明,该仪器在石化、核电站及压力容器等领域有着广泛的应用前景。
A portable ultrasonic P-scan imaging system for inspecting the weld in austenitic steel has been developed by combining computer and signal processing with ultrasonic nondestructive testing. The system has the advantages of high defect resolution, accurate positioning, clear image and easy operation. Test in Beijing Yanshan Petrochemical Corporation shows that the system has wide application prospects in the fields of petrochemical industry, nuclear plant and pressure vessel.
