In the prior art, due to the linearity of the outer plates, bending processing is required in the workshop. Large-sized outer plate panels are formed on one side using carbon dioxide welding, which requires manual + trolley welding multiple times, and the welding time is long; and the outer plate panels require all UT qualified requirements, and it is difficult to repair after defects are found; there are many temporary fixing plates used in the assembly of the outer plate seams, which need to be removed and polished later, which takes time and affects the appearance of the outer plates; there are defects on the inside of the panel seams, which are left for repair and UT flaw detection after carbon planing, which greatly increases the working hours.
[0003] In the prior art, when the outer panels are assembled, a specific shape of the jig is selected according to the shape of the outer panels. The required jig needs to be customized, and different jigs need to be replaced for different hulls and outer panels of different curvatures, which cannot meet the assembly positioning requirements of various outer panels.
