摘要： This welding method is a flash butt welding method of a pair of track rail steel pieces, having: a preheating process in which electric current is made to flow for a predetermined time in a state in which the welding surfaces of a pair of track rail steel pieces are forcibly brought into contact with each other, and vicinities of the welding surfaces are heated by resistance heating; a former flashing process in which flashing is partially caused in the welding surfaces, and the welding surfaces are heated by the resistance heating and arc heating of the flashing; and a latter flashing process in which the flashing is furthermore caused throughout the entire welding surfaces, and the entire welding surfaces are uniformly heated by the resistance heating and arc heating of the flashing, in which a latter flashing velocity is 2.1 mm/sec to 2.8 mm/sec in the latter flashing process.

摘要： The present invention concerns an insulating joint for electrically insulating a pair of adjacent rail sections of a railway track, each rail section extending along a longitudinal axis and defining at least one connecting surface substantially perpendicular to the longitudinal axis and a plurality of lateral surfaces extending along the longitudinal axis. The insulating joint comprises a joint body having substantially the same cross section as the rail sections and defining two contacting surfaces, each contacting surface being intended to be in contact with the connecting surface of one of the rail sections. The joint body is made from an insulating material comprising a reinforcing structure made of metal or carbon fibers, the reinforcing structure being placed inside of the joint body with a distance from the contacting surfaces.

摘要： A welding assembly (1) for welding two rails (2) of a track includes two rail clamping units (5) movable towards one another in an assembly longitudinal direction (4). A power rail (10) provided for power transmission is configured as an assembly guide (3), extending in an assembly longitudinal direction (4), which is spaced from displacement drives (11) and connects both rail clamping units (5) to one another. The power rail (10) is equipped with a cooling device and displaceable in the assembly longitudinal direction (4) relative to the rail clamping unit (5) equipped with the power rail contacts (8).

摘要： A rail repair method enables repair of rails and rail-like structures. A rail defect is initially identified and removed as contained within a volumetric material portion so as to form a contoured void while maintaining continuity of the rail opposite the void. A pre-formed insert is then placed into the void thereby effecting a rail-to-insert interface. Current is driven through the interface as force directs the insert against the rail. Resistance heat and pressure weld the insert to the rail. The flash welding aspects remove oxides and other impurities from the interface, and the forge welding aspects create a robust solid state weld. Excess material, whether flash, rail, or insert-based, is removed during the finishing processes to provide a virtually seamless rail repair. The solid state weld repair methodology may be used to repair any number of targeted metallic rail-like structures.

摘要： The process for metallically connecting the faces of rods. Axially normal dressing at least two rod free ends, then placing the cross sectional surfaces of the rod free ends one against another under pressure. Oscillating the two rod free ends in the opposite direction to one another, whereby frictional heat is generated on the contact surfaces of the rod free ends. Further, when the conditions for a metallic connection are met, the rod free ends are axially aligned and the pressurization of the cross sectional areas is increased. Resulting in the rod free ends being connected to one another over the entire surface. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

摘要： A welding method and apparatus for flash butt welding adjacent ends of axially aligned railway rails includes a base frame and fixed and movable platens supported on the base frame. The platens support rail sections and are under the control of controller means operative to automatically move the movable platen through a predetermined distance/velocity relation as electrical power is inputted into the rail ends during straight flashing, preheating, flashing and upsetting phases of a welding cycle. The controller includes PID feedback loops operative to maintain the predetermined platen distance/velocity relation with entry of a single parameter by the operator. Significantly improved quality and repeatability of rail welds are obtained.
