Rail welding brings more than flash
The process removes a railhead defect by cutting a notch from the railhead and electric flash-butt welding a rail steel insert into the notch. Morris says the process has been through extensive testing; including sample welds in track at TTCI that have exceeded 250 mgt to date. The Head Defect Repair welder (HDR) is a process that repairs ...
