Application of Laser Machine in shipbuilding Industry

In recent years, precision shipbuilding and rapid shipbuilding have become the main trends in the development of the shipbuilding industry. The shipbuilding industry mainly uses steel plate as the main raw material. The use of laser cutting plates can replace some die-cutting methods that require complex large molds, greatly reducing production cycles and reducing costs. In addition, the use of a laser cutting machine to cut off the assembly margin eliminates the phenomenon of on-site trimming, reduces labor and material waste, significantly speeds up the assembly of the frame, and significantly improves the quality of the assembly.

Processing Advantages of Laser Cutting Technology in the Sheet Metal Processing

The traditional method of cutting hull plate parts in the shipbuilding industry mainly uses flame cutting, plasma cutting, shear processing and laser cutting. These cutting methods have many disadvantages compared to laser cutting. The laser-cut marine steel plate has the advantages of good cutting quality, good verticality of the cut surface, no slagging phenomenon, thin oxide layer, smooth surface, no need for secondary processing, direct welding, small thermal deformation, and high curve cutting accuracy.

In the shipbuilding industry, fiber laser cutting prevents the low-temperature plasma from cutting the ribs. In order to ensure the gap of the assembly line, the cutting capacity is set on the ribs and repairs are carried out according to manual services, resulting in uneven repair quality. In turn, the labor cost of the assembly line, the cycle time of the assembly line, and the waste of raw materials and labor costs are reduced. According to the marine steel plate cut by fiber laser, the slit has high cost performance, good verticality of the wound surface, no slag, thin air oxide layer, smooth surface, no need to re-production and processing, can be immediately welded by welding, and the thermal expansion is small, the curve graph laser cutting Accuracy, reduce the mutual coordination of comprehensive working hours, and establish an obstacle-free laser cutting high-strength shipboard. The error of the amount of voids in the ship’s structural members.

As a non-contact, non-polluting, low-noise, data-saving green processing technology, laser cutting machine has shown the characteristics of digital automation and intelligent flexible processing. Therefore, laser processing equipment is more and more widely used in the shipbuilding industry, especially laser cutting, welding and other processing techniques.
