An important option for laser cutting machine ship industry upgrade
Publish Time: 2021-01-23 Origin: laser cutting machine
Since China first domestically-made aircraft carrier Shandong ship was delivered to the Navy, foreign market research institutions have issued a report predicting that in the next few years, China’s shipbuilding industry will still have a lot of room for development, and technological innovation capabilities will enter the world.Shipbuilding goes ahead.
China has always been a major heavy industry country, and has been known as the "world factory". In recent years, many "best in the world" and "best in Asia" ships have come out, which proves the rapid rise of China's shipbuilding industry. Nowadays, "precision shipbuilding" and "fast shipbuilding" have become the main trends in the development of the shipbuilding industry, and laser cutting technology has developed rapidly, accounting for more than 70% of the entire laser processing industry.
The continuous development of shipbuilding technology has led to major changes in shipbuilding materials and ship design. Laser technology has its uniqueness in shipbuilding, which is closely related to the processing and application characteristics of the ship itself and the characteristics of the lasermanufacturing system.
Steel is the most common industrial raw material, and it has many years of history and experience in cutting steel. However, ships are life-carrying tools, and the requirements for their manufacturing materials are very high. A small skew or a small problem in the plate cutting may cause disaster for the entire ship. Therefore, laser cutting machines with no impact on raw materials during cutting, high precision, and high safety factor will soon become the mainstream of the entire shipbuilding sheet metal manufacturing industry.
The marine steel plate cut by laser has good slit quality, good verticality of the cut surface, no slag, thin oxide layer, smooth surface, no secondary processing, direct welding, small thermal deformation, high curve cutting accuracy, and reduced coordination Working hours, to achieve barrier-free cutting of high-strength ship plates. This provides a guarantee for the quality of raw materials in the shipbuilding industry, thereby reducing assembly workload, assembly cycle, material and labor costs.
However, with the improvement of laser processing system equipment technology, it is expected to gradually open up China's shipbuilding market space in the later period, and the large-scale popularization of laser cutting and welding technology in the shipbuilding industry is just around the corner.
