    Abstract: The system comprises a mold (6) which in turn comprises: a weld cavity (4), housings (5) for the components (1) to be welded, a crucible-funnel (7) communicated with the weld cavity (4) for housing filling material (3), at least one additional cavity (10) for housing an exothermic mixture (2); and an inner shell (11) that separates the crucible-funnel (7) and the at least one additional cavity (10) to transmit heat produced in the exothermic reaction from the additional cavity (10) to the crucible-funnel (7). It allows the exothermic mixture to be isolated to avoid contact with the filling material (3) and to prevent it from reaching the weld cavity (4). The system can further include a first filler (13) and a second filler (16), arranged to be mounted over the mold (6) for introducing the filling material (3) and the exothermic mixture (2), respectively.

    Abstract: 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.

    Abstract: A method for manufacturing an engine block is disclosed. In embodiments, the method includes forming an expansion hole in a block body of the engine block that encircles an engine block bore at a head face of the engine block. The method also includes placing an insert into the expansion hole, the insert including an insert body. The method further includes placing a reaction material between the insert and the block body. The method yet further includes forming an insert bond layer between the insert and block body using the reaction material. The method still further includes forming an insert bore through the insert body.

    Abstract: 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.

    Abstract: 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.
