NONDESTRUCTIVE TESTING OF HIGH STRENGTH STEEL WELDS BY NEUTRON RADIOGRAPHY

The use of neutron radiography as a method of nondestructively testing high strength steel welds is examined for technical feasibility and procedural evaluation. Four test samples constructed of HY-80 steel are used to develop accurate radiographic procedural information in order to optimize the quality and minimize error in producing neutron radiographs at MITR. Variations in the basic radiographic procedure were made in order to determine the ability of neutron radiography to find defects in the four weld samples. Attempts were also made to artificially enhance the ability of neutron radiography to pickup surface defects that conventional radiographs are unable to do. The samples were also tested by various other nondestructive test methods, namely ultrasonics, magnetic particle, and eddy current examination. The results of these tests are compared with the neutron radiographs and conventional gamma radiographs of the samples.
