Application of laser cutting machine in shipbuilding industry

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 “fast shipbuilding” have become the main trends in the development of the shipbuilding industry. Laser cutting machine technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry is mainly based on steel plate raw materials. The use of laser cutting plates can replace some punching processing methods that require the use of complex and large molds, greatly shortening the production cycle and reducing costs. After the laser cutting machine is used to cut the material, the assembly margin is eliminated, the phenomenon of on-site repair and cutting is eliminated, the labor and material waste are reduced, the frame assembly speed is significantly accelerated, and the assembly quality is significantly improved.

At present, the cutting methods of hull plate parts in the shipbuilding industry mainly adopt flame cutting, plasma cutting, shearing processing and laser cutting. Compared with laser cutting, other cutting methods have many shortcomings. In the field of shipbuilding, laser cutting avoids the need to set a trimming allowance on the ribs to ensure the assembly gap when the plasma is blanking the ribs, and the trimming is performed manually, resulting in uneven trimming quality. occur. Thereby reducing assembly workload, assembly cycle, waste of materials and labor costs.

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