The present invention relates to a rail carriage for driving a curved surface and, more specifically, to a rail carriage which is attached on a curved surface and transports a rail, on which a welding carriage is driven, in order to automatically weld stern installed on a hull when building a vessel and a curved surface of stern to be safe and easily; of which an inclined angle is adjusted by being interlocked with an inclined angle of the curved surface in order to maintain a constant welding interval corresponding to the curved surface; which relieves the shock generated in driving as an integrated suspension structure is applied to an idling wheel unit. For the same, the welding rail for welding a curved surface of the present invention includes a transfer carriage which is attached to the front surface of a rail combined structure and which transfers the rail combined structure on which the welding carriage is mounted to the welded portion; and the rail combined structure of which the inclined angle is adjusted by being interlocked with the inclined angle of the curved surface. |
