As described above, the traveling vehicle for a welding device according to the present invention is transmitted from a drive source via a power transmission mechanism by, for example, supporting both ends of the vehicle on which the welding device is mounted. A drive shaft that is rotated by a drive force, is fixed to the drive shaft, is opened on the upper surface of a rail laid above the work to be welded, and meshes with a rack tooth engraved on the upper portion of the rail, and is a bogie. The gear train that moves to the position where welding is performed is supported by a pinion engraved on the outer peripheral surface, bearings installed on both sides of the bogie, and connected via a power transmission mechanism such as a drive shaft and a belt. It is fixed to the axle, and rotates with the rotation of the drive shaft, travels above the workpiece body, moves the bogie to a position where welding is performed, at a position below the lower end of the outer peripheral surface of the pinion, A running wheel having a ground contact surface is provided.

As described above, the traveling carriage for the welding device is used for traveling on rails and traveling on wheels. The driving shaft is rotated by driving power transmitted from a driving source such as an electric motor, and is fixed to the driving shaft. The traveling pinion for traveling on the rail can be rotated for traveling, and its driving power is also transmitted to the traveling wheels from the rotating drive shaft formed by a power transmission mechanism formed by a toothed belt or the like. By rotating the traveling wheel, it is also possible to travel on a workpiece on which no rail is laid.

3) When it is considered that welding by rail traveling is not necessary, or when rail traveling is difficult due to an obstacle or the like, only a truck is set on the work to be welded, and wheel traveling is maintained. Since welding can be performed, cost increase due to an increase in length of the rail can be prevented, and working time can be reduced.
