    Abstract: The invention relates to a process for the aluminothermic welding of rails, the aluminothermically produced steel being poured into a refractory mold surrounding the rail ends which are to be joined, and alloying additives being contacted with that part of the steel which runs out of the reaction crucible and forms the weld in the rail head region, wherein the alloying with the alloying additives is carried out after the completion of the aluminothermic reaction and separation of the steel from the slag during tapping and before the steel runs into the casting cavity formed by the mold, and the overflow in the casting mold is closed.

    Abstract: A machine for flash-butt welding of rails, incorporates two tong-type clamping devices made in the form of two two-arm levers carried by a common central axle with insulation from each other and capable of being displaced along the axle relative to each other by two flashing-upsetting hydraulic cylinders connecting them and having bimetal current-carrying rods. Each of the two-arm levers is hinged at one end to the rod or the clamping hydraulic cylinder case, respectively, and the other end is fitted with the clamping and current-carrying jaws. Two welding transformers built into the hollow two-arm levers of one of the two tong-type clamps are joined by current-carrying jumpers through the current-carrying part of the rods of the flashing-upsetting hydraulic cylinders to the current-carrying clamping jaws. A clamping hydraulic cylinder is made with a hydraulic intensifier built into its rod. A reflux valve with a calibrated spring and shank is built into the plunger-rod of the hydraulic intensifier, and a pressure valve is mounted on the hydraulic intensifier cover-lug, this valve being connected by the internal valves with the hydraulic intensifier cavities. The flashing-upsetting hydraulic cylinders being made in the form of tandem-cylinders, wherein two pistons separated by a partition are mounted on a common rod in each hydraulic cylinder.

    Abstract: A rail alignment device and a shear head are suspended from a trolley running over a rail welding machine. The alignment device comprises structure forming a downwardly-opening bight and carrying locating stops, clamping cylinders and transducers with sensing plungers all of which project into the bight. The rail ends to be butt-welded are received within the bight for alignment. One of the rails is clamped against the stops by the cylinders. The location of the other rail relative to the structure is sensed by the transducers and the machine clamps are adjusted until those transducers indicate alignment of the rails. The device is then removed and stored remote from the gap, with the shear head, during welding. The shear head comprises a horseshoe-shaped back plate which carries three cutting tools. An arm, which is pivotally mounted on one of the ends of the back plate and adapted to be latched to the other end to close the bight of the back plate, carries a fourth cutting tool. After welding, the shear head is lowered into the gap until its upper tool abuts the top of the welded rail between the weld and the movable head. The arm is raised and latched automatically to complete a continuous frame of cutting tools around the rail. The shear head is then driven across the weld by the movable head to remove weld upset.

    Abstract: The present invention provides an electrical sensing apparatus supported on a welding machine for movement toward and away from a working position adjacent to and opposite the end sections of the rails that are to be butt welded together. Movably supported on the apparatus for movement transversely of the rail end sections, when the frame is in a working position, are sensor assemblies that includes for each rail end section a pair of web contact switches and a crown contact switch, each of which switches is actuated when contacted by a corresponding rail end section. The web contact switches are initially set in a reference position or plane corresponding to a laterally aligned position of the rail end section wherein all the web contact switches are in engagement with a side surface of the rail web sections. In the alignment of the rails to be welded each sensor assembly is automatically controlled for successive movements of the web contact switches into and out of contact engagement with a corresponding web side surface of the rail end sections until all of the web contact switches are in simultaneous engagement and located within the reference position or plane to define the laterally aligned positions of the rail end sections. Thus, each time a web contact switch is actuated, the rail end section corresponding thereto is transversely adjusted toward a laterally aligned position. This cycle of operation is automatically repeated until the rail end sections are in lateral alignment. The rail end sections are then vertically adjusted into engagement with corresponding crown switches into axially aligned positions. The rail end sections are then locked against relative movement and butt welded together.
