As the top of the industrial chain, “precision manufacturing” is the core of profit and the most lucrative part. Under the general situation of comprehensive revitalization of China’s manufacturing industry, “precision manufacturing” has become the last and most important weakness of China’s economy. Aircraft represented by airbus and Boeing, cars represented by general motors and Volkswagen, ships represented by aircraft carriers and luxury cruise ships, all need a large number of precision manufacturing products. Among them, the shipbuilding industry mainly USES steel plate as raw material, so the processing requirements of raw steel are relatively high in terms of precision, speed and productivity. With the rise of laser pointer cutting technology, laser cutting machine has been widely used in shipbuilding industry.
Instead of traditional cutting methods such as stamping, cutting plate and plasma, laser cutting technology has occupied the mainstream market of sheet metal processing in the shipbuilding industry. Laser cutting technology brings high efficiency and high precision metal processing, short production cycle and low production cost to shipbuilding industry. Laser cutting for planking cutting, with high precision, small thermal deformation, reduce the secondary processing, such as milling, drilling, etc.), transshipment, grinding, especially small circle, small hole, and the advantages of surface processing, conform to the requirements of the hull section ZhuanPei precision, can fully guarantee the frame assembly clearance is controlled in the range of 1 mm, but its utility in steel cutting speed relative to plasma cutting. This provides a guarantee for the quality of the equipment in shipbuilding industry, thus reducing the workload of assembly, assembly cycle, material and labor cost waste.
As early as November 2017, China’s shipbuilding industry surpassed South Korea in the number of new orders it received in the whole year, ranking first in the world. However, China’s investment in research and development of Marine equipment is seriously insufficient, the green technology in shipbuilding process is still backward, and the high-end shipbuilding capacity still lags behind Japan and South Korea.
Laser cutting machine as a non-contact, non-pollution, low noise, material saving green processing technology has begun to show the characteristics of digital automation, intelligent flexible processing, with China’s independent research and development of high power laser also began to scale into the installation stage, which forced the imported laser products began to further reduce prices.
The market space of laser processing system equipment and shipbuilding is expected to open gradually, and laser cutting and welding technology is expected to be popularized on a large scale in the shipbuilding industry.
