... on the Delaware and Hudson Railroad at Albany, NY to produce long rail sections. In 1938, a researcher at the Electric Railway Improvement Company invented a copper-base aluminothermic process for welding copper conductors to steel rails. Currently, thermite welding is widely used in the field welding of track...
