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： This invention relates to an improvement in the process for performing aluminothermic rail connection weldings, in which the rail ends to be welded together and being laid with a gap are enclosed with a fireproof, prefabricated casting mold producing a weld reinforcement covering the gap, and aluminothermically-produced steel is poured into the casting mold cavity, the improvement comprising pouring the steel melt into the casting mold in the form of at least two separate casting streams positioned opposite each other in the longitudinal rail direction, whereby the casting streams are so guided that they will intermix approximately in the area of the rail head center of the two rails to be welded together. The invention also relates to a casting mold for performing the process.
