探讨焊缝超声相控阵检测探头参数和仪器参数对缺陷检测图像显示的影响,指出相控阵参数的选择应以获得最小声束焦点为目标,其中声束发射窗口和频率是最关键的参数。要进行高质量的相控阵检测,必须掌握相控阵参数选择与缺陷图像显示的相关性。
Discuss the influence of ultrasonic probe parameters and instrument parameters on defect detection image display. It is pointed out that the selection of phased array parameters should be focused on obtaining the minimum beam focus. The beam emission window and frequency are the most important parameters . To carry out high-quality phased array detection, we must know the correlation between phased array parameter selection and defect image display.
