The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. The application of laser technology in shipbuilding has its uniqueness, 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. Laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry mainly uses steel plate as the main raw material. The use of laser cutting plates can replace some die-cutting methods that require complex large molds, greatly reducing production cycles and reducing costs. After the laser cutting machine is used to cut the material, the assembly margin is eliminated, the phenomenon of on-site trimming is eliminated, labor and material waste are reduced, the frame assembly speed is significantly accelerated, and the assembly quality is significantly improved.

At present, the cutting method of hull plate parts in the shipbuilding industry mainly adopts flame cutting, plasma cutting, shear processing and laser cutting. Other cutting methods have many disadvantages compared to laser cutting. In the field of shipbuilding, laser cutting avoids the need for plasma to cut the ribs. In order to ensure the assembly gap, a cutting margin is set on the ribs and manual cutting is performed, resulting in uneven cutting quality. occur. Thereby reducing assembly workload, assembly cycle, material and labor costs.

Laser cut marine steel plate with good cutting quality, good verticality of the cut surface, no slag, thin oxide layer, smooth surface, no need for secondary processing, can be directly welded, and has small thermal deformation, high curve cutting accuracy and reduced coordination Man-hours to achieve obstacle-free cutting of high-strength ship plates.

In the domestic shipbuilding industry, laser cutting does not occupy a dominant position. The main reasons include: ① laser cutting costs are higher than traditional cutting methods; ② large-scale equipment for laser cutting is not suitable for the manufacturing characteristics of the shipbuilding industry, such as on-site construction, segmented operation, The working environment is complicated, etc .; ③ There is no obvious advantage in cutting efficiency, especially for heavy plate cutting in the shipbuilding industry; ④ The maintenance of laser equipment is complex, which requires high workers and high costs. Aiming at the special requirements of the cutting machine for the ship's stern plate work and the diversity of the processing shapes of the profiles used in the hull structure, the current status of the industry.
