The currently availability of rail profiles and steel grades have been systematically assessed to arrive at the recommendations of the most appropriate rail profiles and steel grades for use in the current project, involved with the development of new rail welding technologies.
The properties of the various available rail grades have been collated and the determination of additional properties that directly reflect the resistance of the steel grade to the known degradation mechanisms has been recommended. The combination of existing and the proposed rail steel properties will be used to establish a benchmark against which the properties of the welds using the proposed processes could be adjudged. Determination of similar properties has been recommended for welds made using current rail welding technologies.
