China has always been a large country of heavy industry, known as the "world factory". In recent years, the advent of many "world's largest" and "Asia's largest" ships is enough to prove the rapid rise of China's shipbuilding industry. Nowadays, "precision shipbuilding" and "fast shipbuilding" have become the main trends in the development of shipbuilding industry. Laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry mainly uses steel plate raw materials, and uses laser to cut plates. Compared with the previous punching process, it greatly shortens the production cycle and reduces costs. After using laser cutting machine to cut and cancel the assembly allowance, 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, the cutting methods of hull plate parts in shipbuilding industry mainly include flame cutting, plasma cutting, plate cutting and bending processing, and laser cutting. Compared with laser cutting, the previous ones have many shortcomings. In the field of shipbuilding, laser cutting avoids the phenomenon of uneven cutting quality caused by setting cutting allowance on the plate and manual cutting in order to ensure the assembly gap when plasma blanking the plate. So as to reduce the workload of assembly, assembly cycle, material and labor cost waste.
A report released by foreign market research institutions is expected to show that in the next few years, China's shipbuilding industry will still have a lot of room for development, and its scientific and technological innovation capacity will also enter the advanced ranks of shipbuilding in the world. With the improvement of laser processing system equipment and technology, China's shipbuilding market will be opened up. The marine steel plate cut by laser has good cutting quality, good verticality of the cutting surface, no slag, thin oxide layer, smooth surface, no secondary processing, direct welding, small thermal deformation, high curve cutting accuracy, reduced matching hours, and 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 also bound to be the trend in the future.
