AAR STUDIES OF BUTT WELDED RAIL JOINTS

The purpose of this study was to obtain a correlation between defects shown by radiographs of thermit butt welds in track and results obtained in rolling-load tests in the laboratory. Thermit welds in the Canadian National Railway and the Denver & Rio Grande Western Railroad were evaluated. The Research Center's repeated load tests did not correspond exactly to service conditions. More study is needed on the effectiveness of the radiographic examination technique in determining if thermit welds contain defects that would seriously impair their serviceability in track.
