Metal Used For Welding Railway Tracks. The thermite welding railroad has low strength low quality high breakage rate poor overall performance. You might be thinking about gas shielded equipment oxy-acetylene welders and arch welders but thats hardly the case when it comes to railroad welding.
Or Railend 932-0 wire 116 at varying currents up to nearly 300 amps. This type of steel is great for heat treating. This is a medium carbon steel with 07 to 08 carbon and 07 to 1 manganese.
Thermit welding is an effective highly mobile method of joining heavy section steel structures such as rails.
Plus it is such a large section being welded especially with a 110V welder even if it is stick it sucks the heat right away from the weld joint. In the railroad construction it is used to weld railroad tracks. Railroad rail is a high strength low alloy material with higher carbon content with added manganese for toughness. Railroad thermite welding is a welding method that uses the heat of chemical reaction as the heat source.
