[0002] During the construction of the hull, the hull parts are prone to deformation during processing and welding, and pyrotechnics are needed to correct the deformed parts to ensure the overall quality and performance of the hull. Pyrotechnics uses the thermal expansion and contraction characteristics of metals to heat the deformed parts. The volume of the deformed parts expands due to heat. Due to the restrictions of the surrounding areas, the heated areas will be squeezed from the surrounding areas, and the compressive stress will cause plastic deformation in the heated areas. During the cooling process, the heated areas shrink, and the reverse deformation is obtained to offset the original deformation, thereby correcting the deformation.
