[0002] During shipbuilding, numerous steel plates require butt welding. To ensure welding quality, automatic plate welding machines are often used for butt welding of large steel plates. These machines have a welding mechanism in the center, with support platforms on both sides to support the plates to be welded. Workers use hoisting equipment to lift the plates onto the support platforms. Large steel plates often warp or deform during hoisting, initial handling, and transportation. To ensure welding quality, workers manually straighten the plates on the support platforms to achieve the required flatness. Then, the plates are pushed towards the welding mechanism, creating a uniform butt joint on either side. The welding mechanism is then activated to weld the two plates. However, manually straightening the plates on the support platforms is labor-intensive, time-consuming, and requires a high level of skill, hindering rapid ship delivery. Summary of the Invention
