Abstract
A process for welding metallic sections that includes providing first and second metallic sections to be welded together, and wherein the welded rail sections will include a weld fusion zone that further includes a weld terminus at each rail section; providing thermite welding dies for use in welding the metallic sections together; covering the thermite welding dies with an oxide displacing or oxide dissolving flux added locally to the edges of the thermite welding dies that are immediately adjacent to the weld fusion zone and the metallic sections; positioning the thermite welding dies on the metallic sections in the region where the metallic sections are to be joined together; and initiating an exothermic reaction between the thermite welding dies and the metallic sections by introducing molten metal into the region where the metallic sections are to be joined together, wherein the exothermic reaction creates a weld between the metallic sections.
