According to statistics, from January to July 2022, the world's shipbuilding completion volume was 47 million deadweight tons, new orders were 50.36 million deadweight tons, and handheld orders were 215.4 million deadweight tons; The three major indicators in China have the highest market share, reaching 44.4%, 51.1%, and 48.1% respectively.

After years of development, China's shipbuilding industry continues to grow and has become an important force in the international shipbuilding industry. It has strong international competitiveness and is a pillar industry in the national economic lifeline.

Although China's shipbuilding capacity has ranked among the top in the world, the problems of poor overall technical level and low development level are more prominent.

Currently, the world has entered the era of "Industry 4.0" development, and green and intelligent shipbuilding is the future development trend. Nowadays, major shipyards in Europe, America, and Japan have extensively adopted laser processing technology.

With the in-depth exploration of the application of 10000 watt laser, the application of laser in heavy industries such as shipbuilding and machinery has been unleashed with greater potential. Advanced and efficient laser processing technology plays an important role in improving ship construction efficiency, reducing ship construction costs, and improving ship construction quality.

The shipbuilding industry is a major player in metal welding and cutting, and one of the main processes involved in its manufacturing is cutting and welding.

In terms of cutting, ship manufacturing mainly relies on steel plate raw materials, with high requirements for plate raw materials. Any small deviation or problem in plate cutting can lead to a disaster for the entire ship. At present, the main methods for cutting steel plates in shipbuilding include flame cutting, plasma cutting, shear processing, and laser cutting.

Compared with laser cutting, other cutting methods have many shortcomings. Laser cutting makes up for the defects of plasma cutting and flame cutting, such as wide slit, poor cutting accuracy, easy to produce harmful gases, and large environmental pollution.

It can not only greatly shorten the production cycle and reduce costs, but also greatly improve the quality of raw materials and plates for shipbuilding. It is an ideal means of preparing materials for modern shipbuilding.

Laser beams can be focused into very small light points, and laser cutting of the same size plate has smaller slits than plasma cutting and flame cutting. The plasma cutting gap is 5-6mm, while the laser cutting gap is around 1.5mm, which can save 6% -9% of the material.

The thickness of the plates required for the deck, rib plates, bracket plates, ribs, side outer plates and other accessories of large ships such as oil tankers and container ships is between 10-40mm.

In addition, some of the thick plate raw materials used in ship manufacturing need to be cut into grooves to facilitate the robustness of later welding. The traditional process of beveling requires at least 5 processes such as plasma cutting, polishing, drilling, milling, and beveling, with 4 transfers and 4-5 workers (positions) to complete.

It also takes a long time and has inconsistent accuracy; Using a 10000 watt laser to cut the groove, only one person is needed, and there is no need for transportation in the middle. The precision is high, and it can be completed in about one-third of the time using traditional technology.

The continuous development of shipbuilding technology in the world has driven the diversification of ship design, requiring more diverse shapes of plates and parts. For complex shapes, traditional processing methods are basically unable to complete them at once, requiring multiple equipment and processes to be combined to produce them, often resulting in unsatisfactory results; The flexible laser technology can process any shape with just one device, surpassing traditional processing methods in terms of speed and effect.

With the development of our country's economy, the demand for wide and thick plates in the market is constantly increasing. Shipbuilding is just one industry, and there is still more potential for Wanwa cutting to be explored.
