Abstract
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.
