laser cutting for ships industry

　　The continuous development of shipbuilding technology has brought about great changes in shipbuilding materials and ship design. The application of laser technology in shipbuilding is unique, which is closely related to the processing and application characteristics of ships and the characteristics of laser manufacturing system. So, what are the specific applications of laser in ships?
　　

In recent years, "precision shipbuilding" and "rapid shipbuilding" have become the main trends of the development of shipbuilding industry. Laser cutting technology has developed rapidly, accounting for more than 70% of the laser processing industry. Shipbuilding industry is mainly based on steel plate raw materials, the use of laser cutting plate, can replace some need to use complex large-scale die punching processing methods, greatly shorten the production cycle and reduce costs. After the laser cutting machine is used to cut off the assembly margin, the phenomenon of on-site repair and cutting is eliminated, manpower and material waste are reduced, the frame assembly speed is significantly accelerated, and the assembly quality is significantly improved.
　　
　　At present, flame cutting, plasma cutting, shear machining and laser cutting are the main blanking methods of hull plate parts in the shipbuilding industry. Other cutting methods have many disadvantages compared with laser cutting. In the field of shipbuilding, low power laser cutter avoids the occurrence of uneven cutting quality caused by setting the cutting allowance on the rib plate in order to ensure the assembly clearance when plasma blanks the rib plate. Thus reduce the workload of assembly, assembly cycle, material and labor cost waste.
　　
　　Through laser cutting of Marine steel plate, slit quality, vertical cutting surface is good, no slagging, thin oxide layer, smooth surface, no secondary processing, can be directly welded, and the thermal deformation is small, the curve cutting precision is high, reduce the working hours, to achieve the barrier cutting of high strength ship plate.
　　
　　In the China shipbuilding industry, laser cutting does not share a dominant market, the main reasons include:
　　
　　1. Complex maintenance of laser equipment requires high requirements and high costs for workers. Some unfamiliar parts of the ship may be unfamiliar to some of the cutting machines, which may be unfamiliar to some of the ship structures.
　　
　　2. Large equipment of laser cutting is not suitable for manufacturing features of the shipbuilding industry, such as on-site construction, segmented operation and complex working environment;
　　
　　3. fiber Laser cutting costs are higher than traditional cutting methods;
　　
　　4. no obvious advantage in cutting efficiency, especially the thick plate cutting in the shipping industry;

3D laser cutting machine Specification

The working mechanism of 3d laser cutting 　　 Laser cutting is the use of high power density laser beam scanning over the material surface, in a very short period of time to heat the material to thousands to tens of thousands of degrees Celsius, so that the material melting or gasification, and then high pressure gas will melt or gasification material blown away from the slit, to achieve the purpose of cutting materials. 　　The working mechanism of 3d laser cutting is relatively different from that of 2d laser cutting. 3d laser cutting requires constant adjustment of laser cutting head position to ensure that the laser cutting head is always perpendicular to the workpiece surface, so as to obtain excellent cutting quality. In actual production, 3d laser cutting program compilation requires the 3d modeling of parts, and then the introduction of 3d programming system generation path, and manual adjustment according to the characteristics of parts, tooling features, to avoid cutting head

　　The principle of laser cutting machine 　　 　　 Laser cutting is to make the irradiated material melt, vaporize, ablate or reach the ignition point by irradiating the workpiece with the focused high power density laser beam, and at the same time remove the molten material by means of the high-speed airstream coaxial with the light beam, so as to realize the cutting of the workpiece. Laser cutting is one of the thermal cutting methods. The principle of laser cutting is shown below. 　　 Types of laser cutting 　　 　　Laser vaporization cutting is mainly used for cutting extremely thin metal materials and non-metal materials (such as paper, cloth, wood, plastics and rubber, etc.). 　　 　　1. Fusion cutting 　　 　　During laser fusion and cutting, metal materials are melted by means of laser heating, and non-oxidizing gases (Ar, He, N, etc.) are sprayed by the nozzle. Liquid metal is discharged by the strong pressure of the gas to form an incision. It only takes a tenth of the energy to
