Application of laser cutting machine in the shipbuilding industry

Published:2021-06-11 Browse:4Editor in charge:DNE Laser (Member of Bystronic)

Shipbuilding technology is constantly developing, and shipbuilding materials and ship design are also changing. The application of laser cutting machines in shipbuilding has unique properties, which is also related to the actual application of the ship itself. The high-precision cutting and high plasticity characteristics of laser cutting machines are highly consistent with the shipbuilding industry. What are the applications of laser cutting machines in the shipbuilding industry?

In recent years, the main development trend of the shipbuilding industry has gradually aligned with "fast shipbuilding" and "precision shipbuilding". Laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry. The shipbuilding industry is mainly based on steel plate materials, and laser cutting plates are used. Compared with traditional punching processing, the production cycle is greatly reduced, and the cost is also saved. The use of laser cutting machines to cut materials can effectively reduce the on-site secondary trimming process and improve product quality.

At present, the cutting methods of hull plates in the shipbuilding industry mostly use flame cutting, plasma cutting, shear bending machine processing, and laser cutting. Laser cutting avoids the need to set a trimming allowance on the plate to ensure the assembly gap when the plasma is blanking the plate, and the trimming is performed manually, resulting in uneven trimming quality. This can reduce the relative workload, production cycle, and labor costs.

The hull steel plate obtained by laser cutting has good cutting seam quality, good verticality of the cut surface, no slag, a thin oxide layer, smooth surface, no secondary processing, direct welding, small thermal deformation, high curve cutting accuracy, and reduced Cooperate with working hours to realize barrier-free cutting of precision boat plates. Laser cutting machines will be used in more shipbuilding companies in the future, and high-power laser cutting machines will inevitably be the future trend.
