Liquid penetrant inspection is a nondestructive method for locating surface cracks and pinholes that are not visible to the naked eye. It is a favored technique for locating leaks in welds, and it can be applied where magnetic particle inspection cannot be used, such as with nonferrous metals. Fluorescent or dye penetrating substances may be used for liquid penetrant inspection.
Fluorescent penetrant inspection makes use of a highly fluorescent liquid with unusual penetrating qualities. It is applied to the surface of the part to be inspected and is drawn into extremely small surface openings by capillary action. The excess liquid is then removed from the part, a "developer" is used to draw the penetrant to the surface, and the resulting indication is viewed by ultraviolet (black) light. The high contrast between the fluorescent material and the background makes possible the detection of minute traces of penetrant.
Dye penetrant inspection is similar to fluoresc

超声波检查是查出，查出和测量表面和表层下瑕疵一个迅速和高效率的非破坏性的方法在焊件和基本材料。 不可能由其他方法发现和甚而崩裂足够小被命名microseparations的缺点，也许被查出。超音波测试利用自然的电子被计时的波浪和声波一样，但一个高音调或频率。 半新的频率在人的耳朵，因此名字听见的那些之上是远的超音波。 声波或振动在被检查直到间断性或密度的变动被到达的金属被繁殖。 在这些点，某些振动能在一支阴极射线管被反射并且被表明。 样式在管液体渗透剂检查的面孔是不是可看见的对肉眼的一个非破坏性的方法为找出表面镇压和针孔。 它是找出泄漏的一个偏爱的技术焊接，并且它可以是应用的不可能使用的地方磁性粒子检查，例如与非铁质金属。 萤光或染料渗透的物质也许为液体渗透剂检查使用。
萤光渗透剂检查利用高度萤光液体以异常的渗透的质量。 它被申请于将被检查的零件的表面和被引入极端小表面开头被毛管作用。 剩余液体从零件然后被取消， “开发商”用于画渗透剂对表面，并且发生的征兆由紫外(黑)光观看。 大反差在萤光材料和背景之间使侦查成为可能渗透剂详细的踪影。
染料渗透剂检查于萤光渗透剂检查是相似的，除了使用那染料可看见的下面普通的光。 通过消灭对紫外光的需要，更加伟大的轻便在设备达到。
因而是被反射的信号的表示法和瑕疵。 超音波方法要求特别商业设备，并且高度技巧在解释要求阴极射线管样式。

是这样吗?呵呵
