In recent years, "precision shipbuilding" and "rapid shipbuilding" have become the main trends in the development of the shipbuilding industry, and 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, and the use of laser cutting plate materials greatly shortens the production cycle and reduces costs compared with the previous processing technology of punching machines. After using the laser cutting machine to cut off the assembly allowance, the phenomenon of on-site trimming 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 shipbuilding industry mainly use flame cutting, plasma cutting, shearing and bending and laser cutting. The previous ones have many shortcomings compared to laser cutting. In the field of shipbuilding, laser cutting avoids the occurrence of uneven cutting quality by setting a trimming allowance on the plate in order to ensure the assembly gap when the plasma is blanking the plate, and trimming it manually. Thereby reducing the assembly workload, assembly cycle, material and labor cost waste.
The marine steel plate cut by laser has good cutting quality, good verticality of the cut surface, no slag, thin oxide layer, smooth surface, no need for secondary processing, can be directly welded, and has small thermal deformation, high curve cutting accuracy, and reduced coordination Man-hours to achieve barrier-free cutting of high-strength ship plates. Laser cutting machines will be applied in more shipbuilding enterprises in the future, and high-power laser cutting machines are bound to be the future trend.
