Laser Cutting Machines in the Marine Industry

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 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 laser in ships?

In recent years, "precision shipbuilding" and "fast shipbuilding" has become the main trend of the development of ship manufacturing industry, laser cutting machine technology has been rapid development, occupying more than 70% of the entire laser processing industry. Shipbuilding industry is mainly based on steel raw materials, the use of laser cutting plate, can replace some of the need to use complex large-scale mold punching and cutting processing methods, greatly shorten the production cycle and reduce costs. The use of laser cutting machine material canceled after the assembly margin, eliminating the phenomenon of on-site trimming and cutting, reducing labor and material waste, frame assembly speed is significantly faster, assembly quality to improve significantly.

At present, the ship industry hull plate parts under the main way of flame cutting, plasma cutting, shear processing and laser cutting. Other cutting methods have many shortcomings compared to laser cutting. In the field of shipbuilding, laser cutting avoids the occurrence of plasma undercutting of ribbed plate, in order to ensure the assembly clearance, and set the trimming margin on the ribbed plate, and trimming by hand, resulting in uneven trimming quality. This reduces the workload of assembly, assembly cycle, material and labor cost waste.

Through the laser cutting of marine steel plate, the quality of the cut seam is good, the verticality of the kerf surface is good, no slag, thin oxidation layer, smooth surface, without secondary processing, can be directly welded, and thermal deformation is small, the curve of the cutting precision is high, reduce the matching man hours, and realize the obstacle-free cutting of high-strength ship plate.
