摘要
在超声波检测中根据锻件反射底波与缺陷波的静态与动态波形特点,可以识别锻件内部缺陷(气孔、夹渣、夹层、裂纹、白点)与伪缺陷(迟到波、三角反射波、61°反射波及其它杂波),对指导锻件生产具有重要意义。
According to the satic and dynamic waveform characteristics of reflective wave and defect ware in ultrasonic testing,we can identify the defect wace porosity,slag, cracks,white spot,interlayer ,and non-defect late wake,triangle reflection wave,external reflection wake and clutter.
