Cast manganese alloy steel is used for trackwork in the U.S. because of the prevalence of railway level crossings. The manganese alloy steel is subject to an exceptional degree of work hardening. Prior to welding the worn rail, the work-hardened layer should be removed by griding to a depth of at least 0.25 in. Nickel-manganese electrodes, carefully selected for diameter and amperage, are used for welding. The metal is deposited in two or more layers to protect the rail from absorbing the extreme heat generated by the welding process. The welded area must be ground down to a straight and level surface, to avoid high spots which work-harden so rapidly under load that permanent stresses result.
