The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. The application of laser cutting machine in shipbuilding has its uniqueness, which is closely related to the processing and application characteristics of the ship itself. The unique high precision and plasticity of laser cutting machine are highly consistent with the shipbuilding industry. So, what are the specific applications of laser cutting machines in shipbuilding?
In recent years, "precision shipbuilding" and "rapid 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 mainly uses steel plate raw materials, using laser cutting plate, which greatly shortens the production cycle and reduces the cost compared with the previous punch processing technology. After using the laser cutting machine to cut the material and cancel the assembly margin, the phenomenon of on-site trimming and cutting is eliminated, the waste of labor and materials is reduced, the speed of frame assembly is significantly accelerated, and the assembly quality is significantly improved.
At present, the blanking methods of hull plate parts in the shipbuilding industry mainly use flame cutting, plasma cutting, shearing bending processing and laser cutting. Compared with laser cutting, the previous ones have many shortcomings. In the field of shipbuilding, laser cutting avoids the occurrence of uneven cutting quality caused by setting a trimming allowance on the board in order to ensure the assembly gap when the plasma is cutting the board, and manually trimming and cutting. Thereby reducing the assembly workload, assembly cycle, material and labor cost waste.
The marine steel plate cut by laser has good slit quality, good verticality of the incision surface, no dross, thin oxide layer, smooth surface, no secondary processing, can be directly welded, and the thermal deformation is small, the curve cutting accuracy is high, and the fit is reduced Working hours, to achieve barrier-free cutting of high-strength ship plates. Laser cutting machines will be used in more shipbuilding companies in the future, and high-power laser cutting machines are bound to be the future trend.
