摘要： Trigger devices for igniting an exothermic reaction is provided. The trigger devices may be flint type trigger devices and electronic type trigger devices. The flint type trigger device has a housing with a spark opening on a rear wall of the housing. A mold mounting assembly is secured to an exterior of the rear wall of the housing. A motor assembly is secured to the inside of the rear wall of the housing. The motor assembly has a flint wheel attached to a shaft of a motor, where the flint wheel is located adjacent the spark opening. A flint assembly is positioned within the housing such that a flint of the flint assembly is in contact with the flint wheel. A controller positioned within the housing is configured to selectively activate the motor to cause the flint wheel to rotate against the flint to create one or more sparks that are ejected from the spark opening.

摘要： A casting mold (6) consists of two mold halves (4, 5), which are intended for setting up on both sides of the welding groove (3) between two rail ends (1, 2) to be connected, thereby forming a casting space (8) representing a cross-sectional profile of the rails. For sealing the casting space (8) between the rail bodies on both sides of the welding groove (3) and the wall portions (9, 10) of the casting mold (6) that are facing this welding groove, inserted in gaps (11, 12) are strips consisting of a compound at least containing expandable graphite, which as a result of heat being supplied during a preheating process expands and forms a reliable seal. In comparison with using filler sand at this point, there is the advantage that a much smaller quantity of compound has to be carried along when working on the laid track.

摘要： An exothermic welding cup and an exothermic welding capsule, wherein the exothermic welding cup comprises a cup, a cover and an igniter; the cup is used to accommodate welding powder, the cup has an opening, and the cover is used to cover the opening; the igniter comprises a heating portion disposed in the cup, and the heating portion has an insulating member and a heating member; and the insulating member is disposed between the heating member and the cover. The exothermic welding cup can avoid the shorting caused by the contact between the heated heating member and the cover. Also, an encapsulation ring disposed between the cover and the cup is configured to seal the welding powder within the cup so as to prevent the powder from falling out, and the encapsulation ring made of stainless steel ensures effective encapsulation of the welding powder within a certain welding time.

摘要： A stress-relief heat treatment method for stress-relief heat-treating a rail which is welded includes arranging at least one pair of an induction heating coil to face the rail at both sides of a welding center along the longitudinal direction of the rail while being separated from the welding center of the rail by 20 mm to 300 mm in a longitudinal direction of the rail and being an axial direction of the induction heating coil parallel to the longitudinal direction of the rail. The method further includes flowing a current to the induction heating coil arranged at one side of the welding center and to the induction heating coil arranged at the other side of the welding center being opposite to each other, and induction heating the rail to a heating temperature of 400° C. or higher and 750° C. or lower.

摘要： A weld kit is presented for use in creating a weld with limited access to a structure. The weld kit contains a back plate being a combination of a thermic material attached to a metallic material. Additionally, the weld kit has a lowering device secured to the back plate. A plurality of tacking nodes travel through both the thermic material and the metallic material of the back plate. The plurality of tacking nodes are operative to accept and distribute heat from a welding arc to create a tack weld at a location where at least one of the plurality of tacking nodes contacts a weld joint. The presented weld kit may be used to repair a damaged enclosed structure. Additionally, the presented weld kit may also be used to create an enclosed structure in a manufacture type environment.

摘要： A process for welding metallic sections that includes providing first and second metallic sections to be welded together, and wherein the welded rail sections will include a weld fusion zone that further includes a weld terminus at each rail section; providing thermite welding dies for use in welding the metallic sections together; covering the thermite welding dies with an oxide displacing or oxide dissolving flux added locally to the edges of the thermite welding dies that are immediately adjacent to the weld fusion zone and the metallic sections; positioning the thermite welding dies on the metallic sections in the region where the metallic sections are to be joined together; and initiating an exothermic reaction between the thermite welding dies and the metallic sections by introducing molten metal into the region where the metallic sections are to be joined together, wherein the exothermic reaction creates a weld between the metallic sections.
