Recently, the application of fiber laser welding technology in shipbuilding and automobile manufacturing has received considerable attention internationally. In developed countries in Europe and the United States, about 50%-70% of auto parts have used laser pointer processing technology, and laser welding and laser cutting are mainly used. Automobile manufacturers such as Shanghai Volkswagen also use laser processing technology to weld parts such as body and box.
Major large shipyards in Europe, America and Japan have adopted laser processing technology in large quantities. For example, the United States has widely used high-strength, low-alloy steel T-shaped members on newly built new ships. Laser welding technology has greatly reduced the weight of ships. In order to meet the needs of ocean flow dynamics, the hull plates are all designed to have complex three-dimensional curvature shapes.
Laser-assisted flat plate forming technology can replace laborious, time-consuming, and dangerous mechanical heating forming processes, and has good application prospects. Shipbuilding companies such as Kawasaki Heavy Industries in Japan have installed high-power laser flat cutting systems. Meyer Werft in Germany also installed four 12KW CO2 lasers to weld ship stiffeners of different lengths.
At present, the United States, Europe and other regions are developing high-power fiber laser industrial processing equipment, and the secondary development of industrial-grade fiber laser processing equipment with 2KW and 6KW output is ongoing. my country has developed a series of low-power industrial fiber laser products.
Small and medium-power laser processing equipment, such as green laser pointer marking machines, engraving machines, cutting machines, welding machines, etc. are also widely used in various industries, but the industrial processing applications of high-power fiber lasers are still blank, and lasers are not even used in my country’s shipbuilding industry.
