[0002] The profiled roof steel structure is a building form based on steel structures. It uses steel as the main structural material, and assembles the structure of the building through components such as steel columns, steel beams, and steel frames to form a stable and firm framework. Commonly used steels for profiled roof steel structures include cold-formed steel sections, hot-rolled steel sections, etc. During the forming and welding process of the profiled roof, a welding device is required to weld the steel plate structure.

[0003] Currently, during welding, manual operation is required to align two steel plates and then perform welding, which is not convenient to use. Therefore, improvement is needed. The prior art CN202420504029.2, a connecting device for profiled steel plates, uses a connecting piece to set a clamping groove for clamping and adapting to corresponding workpieces to facilitate connection.
