This paper gives a description of how the rails were welded for the track and a technical description of the reasons for certain precautionary measures which were required to ensure that adequate welding quality was achieved. The rails for the Sishen-Saldanha Project were produced by three German Steelworks according to the UIC 60 specification and have a mass of 60 jg/m. The UIC 60 rails of 25 m length were flash butt-welded in a stationary welding depot at the Saldanha marshalling yard to form so-called long welded rails of 300 m. These long lengths were then loaded onto a set of flat railcars and transported to the railhead where they were off-loaded, placed in position and thermit welded to form the fully welded track. In addition, friction welding was used in the attachment of earth return connections to the rails.
