After the assembly allowance is canceled by using laser cutting machine, the phenomenon of on-site repair and cutting is eliminated, the waste of labor and materials is reduced, the assembly speed of the frame is obviously accelerated, and the assembly quality is significantly improved.

The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. The application of laser technology in shipbuilding is unique, which is closely related to the processing and application characteristics of the ship itself and the characteristics of the laser manufacturing system. So, what are the specific applications of lasers in ships?

In recent years, "precision shipbuilding" and "rapid shipbuilding" have become the main trends in the development of the shipbuilding industry, and laser cutting machine technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry mainly uses steel plate raw materials, and the use of laser cutting plates can replace some punching methods that require the use of complex large-scale molds, greatly shortening the production cycle and reducing costs. After the assembly allowance is canceled by using laser cutting machine, the phenomenon of on-site repair and cutting is eliminated, the waste of labor and materials is reduced, the assembly speed of the frame is obviously accelerated, and the assembly quality is significantly improved.

At present, the ship industry hull plate parts blanking methods mainly use flame cutting, plasma cutting, shear processing and laser cutting. Other cutting methods have many shortcomings relative to laser cutting. In the field of shipbuilding, laser cutting avoids the occurrence of uneven cutting quality due to the setting of cutting allowance on the rib plate in order to ensure the assembly gap when plasma is blanking the rib plate. This reduces assembly workload, assembly cycle, material and labor cost waste.

The marine steel plate cut by laser has good slit quality, good verticality of the cut surface, no slag hanging, thin oxide layer, smooth surface, no need for secondary processing, direct welding, small thermal deformation, high curve cutting accuracy, reduced coordination time, and barrier-free cutting of high-strength ship plates.
