摘要
针对超声波测厚难以应用于粗晶材料和复杂结构的局限性,提出了一种基于射线成像原理的测厚新方法,分别以焊缝和管子为例,探讨其理论依据和工艺实施方案。
Considering the difficulties in the ultrasonic thickness measurement for coarse grain material and complex structure, this paper puts forward a new thickness measurement method based on radiography principles. Taking example for weld and tube, the paper further provides discussions on the principles and technique.
