Development of a weld restoration process for worn grooved rail

Key Issue

Alternatives to high temperature preheat weld restoration process for worn grooved rail

Developed Solution

A scientifically proven process that challenged the long held industry belief that high carbon steels can only be weld restored using high temperature preheat. This process has a European patent and has been commercially exploited for a number of years with very significant extension of the life of several kilometres of worn grooved rails. IPR for this development is with Tata Steel.

Results

Very significant extension of the life of several kilometres of worn grooved rails.
