The application of 10kW+ laser cutting machine in shipbuilding industry

China became the second country in the world to master the technology after the first 10kW+ fiber laser was launched in 2013 at the “Optical Valley” in Wuhan. 10kW+ laser has gradually realized the industrialization and also started to promote the ultra-high power fiber laser cutting machines in China’s manufacturing industry. 10kW+ laser cutting machine has been a hot keyword in the industry since 2018. It plays a significant role in aerospace, shipbuilding, automobile, energy equipment manufacturing industry. 



In this article, we mainly talk about the application of 10kW+ laser cutting machine in the ship manufacturing industry. In the actual production process of ships, laser cutting and laser welding are two processes, which cost the most time and money in hull construction. In recent years, 10kW+ laser cutting machine is more and more widely used, at the same time “precision shipbuilding” and “fast shipbuilding” gradually become the mainstream of the development in the ship manufacturing industry.


The shipbuilding industry has high precision requirements for the hull segments, and the frame transferring clearance must be controlled within the range of 1mm. Previously, shipbuilding enterprises generally used plasma cutting. Due to the low grade of accuracy, it needs to be manually cutting and polishing, which always leaves uneven cutting quality, residual oxide in the slotted lines. In addition, this increases the workload of assembly, which causes the entire block  and extends production cycle.


The application of the 10kW+ laser cutting machine perfectly solves this problem. 10kW+ laser cutting machine can ensure the high-precision production of the workpiece, with error±0.05mm. Also, with high-speed cutting, the heat affected zone is much smaller than that caused by plasma cutting machine, which effectively reduces the deformation of the workpiece. Take SENFENG 12kW laser cutting machine as an example, it can achieve quality cutting for 30mm carbon steel, 50mm stainless steel 40mm aluminum and 20mm brass. For 12mm carbon steel, cutting speed  can reach up to 2.1m/min.


Besides, due to the small deviation(within ±0.05mm), you don’t have to leave the margin part for polishing. This does not only saves materials, reduces the consumption of redundant labor, but also saves time, and shortens the manufacturing cycle of ships. In other words, the laser cutting machine fits the development trends of “precision shipbuilding” and “rapid shipbuilding”.


Compared with the previous traditional production methods (flame cutting, plasma cutting), 10kW+ laser cutting machine has the following benefits:

1. Low processing cost, less processing process, high efficiency

The traditional process generally includes 5 processes plus 4 times loading and unloading, while 10kW+ laser cutting can simplify the process as: plate transported into the factory, laser cutting (laser cutting + laser bevel cutting + laser drilling) 2 processes. This does not only improve the processing speed, save labor, but also greatly reduces the cost of ship manufacturing.

In addition, 10kW+ laser cutting machine holds superior advantages in dealing with thick plate processing: the speed is faster than traditional plasma cutting, and with the increase of laser power, the cutting speed of 10mm carbon steel plate will continue to increase. Similarly, with the increase of power, the cutting thickness of carbon steel plate is also increasing.


2. More flexible and intelligent

Laser cutting machine with CNC system and 3D robot can help users achieve intelligent, flexible production. 10kW+ plate laser cutting machine with hydraulic lifting auxiliary loading mechanism and auto-exchange platform, can achieve flexible loading and unloading, plate fine adjustment, fast cutting to reduce non-production time. Combined with the high intelligent CNC bus system, 10kW+ laser cutting machine realizes the functions of cutting process setting change, real-time monitoring of cutting state, and whole-process detection and recording of cutting data parameters. Our Senfeng R&D engineers are continuously optimizing cutting process parameters and cutting effect.


3. efficient and precise machining of various shapes of workpiece

Because the shape required by the hull structure is varied, the corresponding need for the 10kW+ laser cutting machine can achieve multi-angle, multi-direction cutting by its intelligent CNC cutting head. With the high intelligent numerical control system, it can process the high-quality workpiece with the cutting seam about 0.03mm, vertical cutting without hanging burrs at the bottom, so as to ensure the overall precision of the workpiece.


4. Easy to maintain, time and effort saving

The light source is the laser beam transmitted through the optical fiber. Compared with the traditional mechanical optical path, this optical fiber transmission mode is simpler, clearer and easier to maintain. With the power distribution cabinet of the 10kW+ laser cutting machine, it is safe, dust-proof and anti-static, which greatly saves the time, energy and maintenance cost.


With all the benefits 10kW+ laser cutting machines possess, we can see its great potential and bright future in applying in not only ship building industry, but also in other heavy industries.
