RAIL END BATTER; CAUSES AND REMEDIES
Causes and remedies of rail end batter are discussed. Four rail joints of 131 RE section with a 0.040-in. batter are welded, using the semi-automatic wire feed method with a modified 4560 wire electrode and gas shielding eliminated. A 700 F preheat and 1100 F post heat are produced with a propane heater. Rail joints are subjected to rolling-load tests. Results are presented of rolling-load tests of four rail joint assemblies, built up with Haynes Stellite modified 4560 wire electrode. It is noted that batter ranges from 0.006 in. to 0.016 in. on joints 69 A and 69 C that ran to 5,000,000 cycles. Hardness obtained on a standard BHN tester on the parent rail metal that was work hardened and on the weld metal before and after work hardening is reported. It is noted that the trend of spalled rail ends with a BHN range of 481-564 before work hardening and 512-600 after work hardening occurs, and that the spalling occurs about 1-1/2 in. away from the rail ends where the porosity is the heaviest.
