Simulation of the impact of preheating temperature on railway aluminothermic welding [PDF]
, 2022 For more than a century, railway rails have been joined using the aluminothermic welding process. The flexibility, compactness of the weld, and ease of execution are all advantages of this process. It is not necessary to use external energy to finish the operation. It is provided by the exothermic effect of the chemical reactions of the elements of the
