Addressing Electrode-Induced Rail Pitting From Pressure Electric Welding
This document provides notice of FRA's intent to issue a Safety Advisory alerting railroads, contractors, and the rail welding industry of the potential for electrode-induced rail pitting and fatigue cracking during the pressure electric rail welding process. Based on investigation and research, FRA believes improper electrode contact to the rail during the welding process can result in electrode- induced pitting that may lead to fatigue fracture and ultimately rail failure. The draft Safety Advisory includes recommendations to help the industry prevent electrode-induced rail pitting and to inspect for and then remediate such pitting if it occurs. FRA invites public comment on all aspects of the draft Safety Advisory.
