Application of laser welding in shipbuilding industry 

In the field of shipbuilding, there are more and more examples of using dissimilar materials, and the welding applications for this material are also more diverse. Because the hull parts and structures are different, the choice of various materials is also different. For example, some parts need tough materials, and some need materials with strong corrosion resistance. Therefore, it is necessary to strengthen the depth of research on the welding process of dissimilar materials. The following describes the application of laser welding in ships.

Application of laser welding in shipbuilding industry

In the early stage of the development of laser welding machine technology, most of the thin-walled materials were welded at low speed. With the continuous availability of higher power lasers, the application of laser welding has gradually penetrated into the field of heavy industry. Compared with the traditional welding process, laser welding process has many advantages, such as more precise and in-depth welding; good coordination of hull components can quickly form profiles; lower requirements on the welding environment, no need for vacuum or rare gas Work in the environment; welding is more flexible, can avoid close contact, so that construction safety is better guaranteed. The advent of laser welding has allowed continuous innovation in the manufacturing process. Especially in shipbuilding, its innovations are mainly focused on the field of hull structure design, through innovation to reduce ship weight and reduce manufacturing costs. 

When the ship is fully welded, the laser welding process can not only weld the same material, but also weld materials of different thicknesses. In the process of steel plate laser welding, if any defect occurs, it will alarm in time to re-weld in time to avoid the phenomenon of strip breakage. In addition, the on-line inspection of the assembly state before welding and the position of the seam, the stability of the welding process, and the quality of the weld after welding, etc., can predict the possible welding defects and the deviation of the seam position.
