Other cutting methods have many disadvantages compared to laser cutting. It is worth mentioning: with the development of laser processing system equipment technology, it is expected to gradually open up Chinese shipbuilding market in the future, and the large-scale popularization of laser cutting and welding technology in the shipbuilding industry is just around the corner. Nowadays, the concepts of “precision shipbuilding” and “rapid shipbuilding” have become the main trend of the development of shipbuilding, and laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry.

Laser cutting technology brings excellent production efficiency, excellent quality metal processing, very short production cycle and low production cost to the shipbuilding industry. At present, the cutting method of hull plate parts in the ship industry mainly adopts flame cutting, plasma cutting, shear processing and laser cutting. The marine steel plate cut by plane laser cutting machine and 3D laser cutting machine has the advantages of good cutting quality, good verticality of the cutting surface, no hanging slag, thin oxide layer, smooth surface, no secondary processing, and it can be directly welded with small thermal deformation, high curve cutting accuracy, mating hour decrease, realizing barrier-free cutting of high-strength ship plates. In the field of shipbuilding, laser cutting avoids the occurrence of uneven cutting quality which happens with plasma cutting. When the rib plate is cut by plasma, and repair allowance is set to ensure the assembly gap, causing uneven cutting quality by manual repairs. In view of the special requirements of the cutting machine for ship outfitting work, the diversity of profile processing shapes used in the hull structure is concerned, as well as the current situation of the industry. In the marine industry, the main application material is steel.

The rapid development of shipbuilding technology and the continuous development of shipbuilding technology have caused major changes in shipbuilding materials and ship design. The minor skew or small problem in the cutting of the plate can lead to the disaster of an entire ship. Laser technology in shipbuilding has its own unique advantages, which is closely related to the processing and application characteristics of the ship itself and the characteristics of the laser manufacturing system.

Steel is the most common industrial raw material, and steel cutting has many years of history and experience. This reduces the assembly workload, assembly cycle, material and labor costs.

Reasons why laser cutting is not dominant, the main reasons include:

①The cost of laser cutting is higher than that of traditional cutting methods;

②Large-scale laser cutting equipment is not suitable for the manufacturing characteristics of the ship industry, such as on-site construction, segmented work, complex working environment, etc.;

③ The cutting efficiency has not significant superiority, especially the thick plate cutting in the ship industry;

④ Laser equipment maintenance is complicated, which has high requirements for workers and high costs.
