RESULTS OF ROLLING LOAD AND SLOW-BEND TESTS OF BUTT-WELDED RAIL JOINTS
Results of 13 rolling-load and 13 slow-bend tests of butt-welded rail joints are described. The butt welded rail joints are made by the thermit (Exomet and Orgotherm process), the electric-flash and the oxyacetylene pressure butt-welding processes, and are submitted for testing to evaluate the various welding methods. Rolling-load tests are made on either use 12 in. or the 33 in. stroke rolling-load machine; slow-bend tests are made on supports 4 ft. apart with a two-point loading 6 in. on each side of the weld. Results of rolling load tests indicate that with the thermit weld orgotherm process and the thermit weld type from Exomet, Inc. a rail broke, but otherwise no failures occurred in butt-welded rail joints. Results of slow-bend tests indicate that a rail broke in each test situation, but that there was good structure in Southern Railroad's Thermit Weld (Orgotherm) specimen.
