    摘要: The present invention concerns a welding mold for butt welding two metal parts by casting a molten filler metal in an imprint defined by a mold. At least one of the components of the mould includes a spacer member shaped and sized so that it can be engaged in a gap between the two parts only if the latter have a mutual separation at least equal to a specific mutual separation, so as to allow the mutual assembly of the components of the mold around the parts to be welded only on this condition. Applications include the welding of railway rails, concrete reinforcing rods and metal bars.

    摘要: A double inclined weld face structure for a jolt-and-vibration-free seamless rail with high bearing capacity relates to the welding of the seamless rail of the rail train, a weld seam of the rail according to the present application forms, at least partly, a double inclined weld face, forming an angle α with the vertical direction of the rail and an angle β with the transverse direction of the rail. The double inclined weld face can further improve the stress state in the weld face of the rail, enhance the bearing capacity of the weld face and eliminate upward and downward jolting and leftward and rightward shaking of a train. The double inclined weld faces of the two parallel rails (1) are arranged in a interleaving way and the interleaving length is greater than the length of a carriage, thus enhancing the running stability and durability of the train and more beneficial to use a simple existing Aluminothermic welding in the weld of the seamless rail.

    摘要: A cover for closing a top opening of a thermite reaction chamber of a crucible is substantially continuous and is secured to an annular filter lining via a bottom peripheral edge for making contact on a top peripheral edge of the crucible. The filter lining is substantially continuous and is suitable for constituting a substantially continuous contact medium between the bottom edge and top edge. The cover is applicable, for example, to thermite welding, e.g., for use in tunnels or underground.
