The invention discloses a welding bogie. The welding bogie comprises wheel pair assemblies, a framework assembly, shaft box hanging systems and braking devices. The framework assembly is of an H-shaped structure formed by a beam and side beams in an inserting connection and installing and welding mode. The framework assembly is located on the two wheel pair assemblies through the shaft box hanging systems. Each braking device is an integrated foundation braking device. The integrated foundation braking devices are hung on the framework assembly through hanging rod assemblies. The framework assembly is formed by the beam and the side beams in the inserting connection and installing and welding mode. The requirement for strength is met, and the structure is simple. Linuoer shock absorber structures are adopted for the shaft box hanging systems, and therefore linear running stability is guaranteed, and the welding bogie adapts to curve passing capacity. Rubber springs are adopted for the shaft box hanging systems, and therefore the shaft box hanging systems have rigidity and damping in the vertical direction, the transverse direction and the longitudinal direction, the structure is simple, and maintaining is easy. The braking devices are the integrated foundation braking devices, and the best braking characteristic can be transmitted through the design principle of a parallelogram.
