Microradiography was used as one phase of a nondestructive evaluation program for inspection of the electron beam braze joining of dissimilar metals. Stainless steel tubing was joined to a gold-copper disk using a Cusil (copper/silver) brazing alloy. A 150-kV x-ray source was used with the radiographs recorded on high-resolution plates. Interpretation of the radiographs was aided by computer graphics displays of digitized film density measurements. Braze intrusion maps were generated indicating the extent of braze penetration into the stainless steel tube. Penetration as small as a few micrometers was observable.
