Application of laser cutting machine in shipbuilding industry
Date:2022-08-16 Publisher:

The continuous development of shipbuilding technology has led to significant changes in shipbuilding materials and ship design. The application of laser technology in shipbuilding has its unique characteristics, 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 laser in ships?

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

At present, flame cutting, plasma cutting, shear processing and laser cutting are the main cutting methods of hull plate parts in the shipbuilding industry. Other cutting methods have many disadvantages compared with laser cutting. In the field of shipbuilding, laser cutting avoids the uneven trimming quality caused by setting trimming allowance on the rib in order to ensure the assembly gap when plasma is used to cut the rib. Thereby reducing the workload of assembly, assembly cycle, and waste of materials and labor costs.

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