The present invention relates to an automatic bending device for deformation correction of a steel plate, and in detail, to implement a configuration of a traveling truck moving in close contact with the surface of the steel plate to correct the deformation of the vertically and horizontally installed steel plate, By implementing the configuration of the working mechanism to heat and cool the work place to bend the work by the automated device, it is possible to obtain the convenience and stability of the work and the quick and excellent work results.

Welding is performed in the most common way of joining steel plate and steel plate or various members and members formed of steel. Such welding melts the welding core material with high temperature heat and welds the molten core material to the joint of each member. This is done by forming beads.

The combination of the iron plate and the iron plate is a process that is essentially performed when a large ship is built. The iron plate is provided with various thicknesses according to the size of the vessel, and the above-described iron plate is welded after the welding operation is performed. Deformation such as warping and bending occurs by heat.
