| | Repair welding of rails (Site not responding. Last check: ) |
 | | Rail wear occurs mainly on curves and hardly at all on the straight but, because of welding problems, a solution must be based on increased hardness through refinement of the pearlite structure and not by increasing the alloy content. |
 | | Fracture of a rail (0.06%C, Ni, Cr, Mo steel) in the roller bearing circle assembly of a dragline, initiated in the heat affected zone at the toe of a tack weld as a result of unsuitable microstructure, welding residual stress and fatigue loading. |
 | | The equipment available in British Rail's Research and Development headquarters for metal spraying, welding and surfacing, and the applications to which it is put in prevention of wear and repair of worn surfaces are described. |
