系统地利用可能得到的所有超声探伤信息和一些并非总是确凿的信息,能够比较准确地判定缺陷的形状和分布。为了鉴别缺陷的实际类型,需要对有关产品的参数结合缺陷的位置,并对缺陷属于平面型,或为体积型应有所了解。只有在识别缺陷的类型之后,才能根据波幅高度,得出缺陷尺寸的精确描绘。目前用于检验锻件缺陷的成象方法仅能对大而孤立的,导致产品报废的缺陷提供精确图解,而对于小缺陷,特别是成群出现的缺陷,这种成象方法常常只展示总体分布,并在此基础上提供缺陷的类型。
Systematic use of all the available ultrasonic flaw detection information and some not always conclusive information, can be more accurately determine the shape and distribution of defects. In order to identify the actual type of defect, it is necessary to combine the parameters of the relevant product with the location of the defect and to know whether the defect is planar or of a volumetric type. Only after the type of defect is identified can an accurate description of the defect size be derived from the amplitude of the amplitude. The current imaging methods used to verify forgings’ defects can only provide an accurate picture of large, isolated defects that result in end-of-life defects, whereas for small defects, especially in clusters, such imaging often shows only an overall distribution , And on this basis to provide the type of defect.
