The manufacturing of the shipbuilding industry is mainly based on steel plate raw materials, so the processing requirements of raw material steel have higher requirements in terms of accuracy, speed, and productivity. With the rise of laser cutting technology, laser cutting machines have begun to be widely used in the shipbuilding industry. The high-precision cutting and high plasticity characteristics of laser cutting machines are highly consistent with the shipbuilding industry. Let Leapion Laser share the application of laser cutting machine in the shipbuilding industry.

The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. In recent years, "precision shipbuilding" and "fast shipbuilding" have become the main trends in the development of the shipbuilding industry.

At present, the cutting methods of hull plate parts in the shipbuilding industry mainly adopt flame cutting, plasma cutting, shear processing and laser cutting.

There are many problems with traditional processing methods, such as: when using plasma cutting

1. Use plasma cutting to blank the ribs. In order to ensure that the assembly gap meets the standard, trimming allowances are set on the ribs. It is necessary to manually trim on-site during on-site assembly, and the quality of the trimming is uneven. 

2. Manual trimming will result in residual oxides in the kerf. At the same time, it also increases the assembly workload, prolongs the assembly cycle, and greatly prolongs the entire segmented construction cycle.

Compared with other traditional processing methods, laser cutting technology has many application advantages:

1. What laser cutting technology brings to the shipbuilding industry is high-efficiency and high-precision metal processing, ultra-short production cycle and lower production costs.

The use of laser cutting machine blanking cancels the assembly margin, eliminates the phenomenon of on-site repair and cutting, reduces labor and sheet waste, and the frame assembly speed is significantly accelerated, and the assembly quality is significantly improved.

2. For ship board cutting, laser cutting has the advantages of high cutting accuracy, small thermal deformation, reduction of secondary processing (such as milling, drilling, etc.), transfer, and grinding, especially small circles, small holes, curved surfaces, etc. It meets the requirements of hull segment transfer accuracy, and can fully ensure that the frame assembly gap is controlled within 1mm.

3. The marine steel plate cut by laser has good cutting seam quality, good verticality of the cut surface, no slag, thin oxide layer, smooth surface, and can be directly welded.

4. The use of laser to cut the plate can replace some processing methods that require large-scale die punching, greatly shortening the production cycle and reducing processing costs.

As a non-contact, non-polluting, low-noise, and material-saving green processing technology, laser cutting technology has the above unique advantages in the application of the shipbuilding industry.
