T形焊缝超声相控阵检测的计算机辅助技术

Computer-Aided Technology of Ultrasonic Phased Array Inspection for T-Weld

超声相控阵技术在T形焊缝中的应用表现出其明显优势,但声波在T形焊缝中的辐射区域不能形象界定,且回波来源的位置得不到准确地判断。针对T形焊缝的结构编译了超声相控阵检测辅助软件,对试样中的人工孔检测表明:采用计算机辅助技术可以实现T形焊缝超声相控阵扇扫声束覆盖及回波信号的识别。

The application of the ultrasonic phased array technology on T-weld shows its obvious advantages.However,the beam areas of T-weld still can not be defined,and can not estimate the position of the echo.According to the structure of the T-weld,the ultrasonic phased array inspection support software is compiled.Artificial sample tests suggests that the computer-aided technology could achieve the beam coverage of T-welded and help to distinguish the echo signal.
