无论用何种无损检测方法,探测材料内部缺陷的形状是目前无损检测领域中没有解决的一个难题。本文是利用CO_2红外激光无损检测方法判断缺陷形状的一次初步尝试。
No matter what kind of non-destructive testing method is used, detecting the shape of internal defects in materials is a problem that is not solved in the field of non-destructive testing at present. This article is a preliminary attempt to determine the shape of defects using CO_2 infrared laser non-destructive testing.
