Application of laser cutting machine in shipbuilding industry

In recent years, "precision shipbuilding" and "rapid shipbuilding" have become the main trends in the development of the shipbuilding industry. Fiber laser cutting machine technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry mainly uses steel plates as raw materials. The use of laser cutting plates can replace some punching processing methods that require the use of complex large molds, greatly shortening the production cycle and reducing costs. After the fiber laser cutting machine is used to cut materials and eliminate the assembly margin, the phenomenon of on-site repair and cutting 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 methods of hull plate parts in the shipping industry mainly use flame cutting, plasma cutting, shearing processing and laser cutting. Other cutting methods have many shortcomings compared to laser cutting. In the field of shipbuilding, laser cutting avoids the problem of setting trimming allowances on the floor plates and manually trimming them to ensure the assembly clearance when cutting floor plates with plasma, resulting in uneven trimming quality. occur. Thereby reducing the assembly workload, assembly cycle, material and labor cost waste.

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