PROBLEM TO BE SOLVED: To provide a self-traveling welding truck which eliminates the welding impossible part of the edge parts in the steel, and also can obtain uniform welding finish at a low cost, when a long-length steel such as a longitudinal steel is automatically welded. SOLUTION: The self-traveling welding truck includes: a motor 110 at the inside of the truck body; and a magnet 120 having attraction effect to the steel sheet to be welded on the horizontal side at the bottom face of the truck body, and is also mounted with a welding torch 130 sliding along the traveling direction of the truck. The truck includes: a differential gear mechanism part 140 rotationally driven by the motor 110; a truck traveling mechanism part 150 connected to one differential side gear constituting the differential gear mechanism part 140 via an axle shaft; and a welding torch slide mechanism 160 connected to the other differential side gear constituting the differential gear mechanism part 140 via an axle shaft.
