A method and system for electroslag strip cladding (ESSC) of rail heads without preheating utilizing twin electroslag strip welding techniques. The twin ESSC techniques include depositing a layer of wear and corrosion resistance cladding material onto the entire running surface of the rail head at a relatively fast welding speed of approximately sixty cm/minute with less than one cm/meter of distortion. The welding speed is achieved by moving a twin ESSC welding head along a rail, with the running surface of the rail head facing upward, or advancing a rail through a space under the twin ESSC welding head, with the running surface of the rail head facing upward, while cladding material is deposited continuously onto the running surface of the rail head.
