PHYSICAL TESTS OF NORMALIZED AND NOT-NORMALIZED OXYACETYLENE PRESSURE-BUTT-WELDED 115 RE RAIL

The welds were made using three 39-ft rails, according to the normal procedure with the exception of not normalizing eight of the welds. The rolling-load tests were made using 48,000-lb and 60,000-lb wheel loads. The data indicate that all the failures produced in the rolling-load tests were from causes other than the effects of normalizing or not normalizing. The slow bend test of two normalized and two not-normalized oxyacetylene pressure butt-welded rails made. The results indicate a trend toward greater load, energy absorption and deflection in favor of the not-normalized tests. The drop tests of two normalized and two not-normalized oxyacetylene pressure but-welded rails were conducted. Again no significant difference can be found in the data for the normalized compared with the not-normalized welds.
