The Real-time Imaging Detection Technology of Brazing Metal Honeycomb

This paper introduces the real-time imaging detection technology during the manufacturing process of brazing metal honeycomb. Traditional radiography is limited by the diameter-ray beam angle and the effective areas of Tran-illumination are small, hence the detection of large-scale honeycomb structure are less efficient; Meanwhile, the imaging deformation of the core grid due to the thickness change of the work piece might occur. The paper uses the real-time imaging technology to dynamically scan the honeycomb structure and to detect defects, and it is proven effective to solve the above problems. At the same time, a satisfactory result was obtained based on the system resolution provided by the resolution test meter.
