Will promote the advancement of shipbuilding technology, but the application of high-power fiber laser in shipbuilding needs to break through some bottlenecks
Recently, China's first 10,000-watt continuous fiber laser was launched in Wuhan “Optical Valleyâ€. Since then, after the United States, China has become the second country in the world to master this technology. The localization and industrialization of 10,000-watt continuous fiber lasers has broken the monopoly of the field in the United States. Ship industry experts said that this will also promote the continuous improvement of shipbuilding technology and promote the application of laser processing technology in the shipbuilding industry.
According to reports, laser technology is a common processing method in the manufacturing industry. Fiber laser is a hot spot in the laser field in recent years, and high-power fiber laser is the most advanced third-generation industrial processing laser. Compared with general lasers, fiber lasers have many advantages, such as high processing precision, intelligent and flexible operation, etc., and their application fields have been extended to metal and non-metal materials in the automotive, marine and aerospace industries. etc.
Zheng Huijin, director of the Welding Technology and Equipment Research Office of the Shanghai Ship Technology Research Institute, said that the application of laser processing technology is more common in European shipping companies. For example, the German Meyer Shipyard has long used lasers for parts processing. At present, some large ship companies in China also use laser processing technology. The application of laser cutting technology in the shipbuilding industry has been relatively mature; in the aspect of welding, since the thermal influence zone of the fiber laser is small, the thermal deformation phenomenon can be significantly reduced, so that the quality and appearance of the ship plate weld can be significantly improved, and the processing efficiency can be improved.
However, high-power fiber lasers are widely used in the shipbuilding industry, and some bottlenecks need to be broken. Zheng Huijin believes that the one-time capital investment of the laser processing system is extremely large. It takes millions of yuan for only one piece of equipment, and the ship enterprises can only meet the production needs only by bulk purchase. Therefore, relevant research institutions and enterprises should accelerate the commercial use of lasers. The process of rapid reduction of product prices, in order to promote the use of a large number of shipping companies. In addition, there are problems between the characteristics of the laser manufacturing system and the processing and application characteristics of the ship industry itself, especially in the aspect of welding, the laser processing precision reaches one tenth of a millimeter, which is proposed for the shipyard's precision management and construction process. Higher requirements.
Wei Zhuyu, an expert on engineering research at Guangzhou Shipyard International Co., Ltd., said that in recent years, the development of laser processing technology has been very rapid, and the use of this technology by some shipbuilding companies has also expanded from the workshop to the dock and underwater. However, from the point of view of actual use, laser cutting equipment sometimes cannot cut thicker sheets, and flame cutting must be used. At the same time, the laser equipment technology is complex, key components need to be replaced on time, and the relevant parameters need to be re-adjusted after replacement. Therefore, ship laser manufacturing technology developers should consider the needs of shipbuilding itself to improve the reliability and durability of the equipment, and actively study the combination of laser technology with traditional and other cutting and welding methods, so that the technology in the ship Manufacturing is more widely used.
It is understood that the 10,000-watt fiber laser is independently developed by Wuhan Ruike Fiber Laser Co., Ltd. The person in charge of the marketing department of the company told reporters that the fiber laser is the core of a series of laser equipment. The 10,000-watt fiber laser developed by Wuhan Ruike has the characteristics of high beam quality, high electro-optical conversion efficiency and maintenance-free operation. It can be widely used. Welding, cutting, brazing, heat treatment, rock and concrete drilling. This technology has been incorporated into the 2013 National “863†Program.
Founded in 2007 in Wuhan Donghu High-tech Zone, Wuhan Ruike is the first high-tech enterprise in China that is currently developing and implementing large-scale production of fiber lasers. Since its inception, the company has been actively engaged in technological innovation and transformation of results in fiber lasers and related applications. In 2012, after the 500-watt continuous single-mode fiber laser was mass-produced, the 1 kW continuous laser was sold and mass-produced, and the 4 kW continuous laser was sold and certified, the company also achieved significant results in the 10,000 watt continuous laser technology. breakthrough.
