EVALUATION OF LINDE'S EXPERIMENTAL 936-89 WIRE FOR BATTERED RAIL END BUILD UP USE

An investigation to evaluate Linde's experimental 936-89 cored wire for rail end build up was conducted based on rolling-load test results, hardness survey results and a metallurgical examination to determine the quality of the weld. Information supplied by Linde relating to the welding procedure indicates that prior to welding, all joints were preheated to 700 F. A Tempil stick was used to determine the preheat temperature. Immediately following the preheat the joints were welded using 425 amperes, 27 volts. Sample rail joint were resurfaced at the butt edge to bring the deposit closer to the edge. These welded, battered rail end sample joints were subjected to rolling-load testing in the 12-in-stroke rolling-load machine. Testing of one sample was discontinued after the joint had been subjected to 4,002,200 cycles in the rolling-load machine because of excessive batter. Testing specimen 154 C was subjected to 2,000,000 cycles in the rolling-load machine. This test was discontinued because of a failure, originally starting as a progressive-type failure from a bolt hole, and later resulting in a head and web separation when the bolts were tightened to a desired tension. Speciments cut from joint 154 A show a normal heat pattern and good weld-metal deposit penetration. A good weld-metal deposit penetration was noted.
