Zusammenfassung:	A fixed rail wedler for butt welding of two rails uses hydraulic transmission mechanism to tightly clamp the rail ends by the jaws of welder and its two welding transformers are directly arranged in clamper. It features its automatic aligning function for the axis of rail and the axis of welder and for the axises of the rails to be welded. An enclosed protecting shield is used to prevent welder from being damaged by molten metal. A smoothing unit is used to make the surface of welded rail smooth. Its advantages are high productivity, improved working environment and high quality and stability of welded rail.
