Welding Railway Iron. It uses 2 lengths of railway iron with mild steel angle welded on the flat side used upside down. To effectivly weld on the Ball of the Rail you must 1st Fre heat the Ball of the rail to 900F or if you have a Digital Therm.
350 degree minimum preheat for the rail before you weld. Electric Arc Welded Rail Ends On main tracks and sidings rail ends that have been previously electric arc welded are prohibited from being thermite welded on rail manufactured after 1975 and on alloy rail. It is always preferred to heat the entire casting if possible.
The rail weld is in comparison to plain rail particularly susceptible to damage formation.
When welding the ends of the two rails are fixed in the mold in advance and then the mixture of aluminum powder and iron oxide powder called thermite is heated in the crucible. To effectivly weld on the Ball of the Rail you must 1st Fre heat the Ball of the rail to 900F or if you have a Digital Therm. Thermite rail welding is to use aluminum and iron oxide including additives to arise redox reaction at a certain temperature. If it dont hold ima quit my day job and just start working the street corners.
