SECOND PROGRESS REPORT--JOINT INVESTIGATION OF CONTINUOUS WELDED RAIL

Report of committee on welded rail includes a brief resume of past research and then continues into the present research area. The first covered is the testing of welded rail joints under repeated wheel load. The procedure, the endurance limit and fractures developed are included. A comparison between welds and joint bars was included. Metallographic tests of the welds are included and such tests as hardness, etching and metallographic examination of the welds are also included. Mechanical tests of the welded joints were also part of the test sequence. A complete comparison of the test are indicative of metal qualities rather than joints, and that the quality of metal is important to the joint strength as weld outline, cracks and other stress raisers in the joint.
