RESULTS OF ROLLING-LOAD AND SLOW-BEND TEST OF BUTT-WELDED RAIL JOINTS

Results of rolling-load and slow-bend tests of butt-welded rail joints are reported. Welding methods include submerged arc, thermit process, and oxyacetylene pressure process with abrasive-wheel-cut weld faces and with variations in upset pressure and Btu input. Welds with magnaflux and ultrasonic indications of defects are also included in tests. It is noted that results, particularly results of submerged arc process, represent initial work on developments needing considerable further refinement. Results on thermit welds are representative of the results obtained in previous test of such welds, except those made by the Southern Railway, which show results meeting the standards established by tests of oxyacetylene pressure butt welds and flash butt welds for the first time. Investigations of welds with magnaflux and ultrasonic indications indicate a lack of uniformity existing in judging these indications at the inspection stations.
