Aluminum and aluminum alloys play a decisive role in various materials used in modern engineering technology. Its annual output is second only to that of steel in the world, and first in non-ferrous metals. If aluminum alloy first emerged in the aviation industry, in recent decades, aluminum and aluminum alloy have been widely used in aerospace, automobile, ship and even home decoration in addition to the aviation industry.
Aluminum alloy welding refers to the welding process of aluminum alloy materials. At present, the main welding processes of aluminum alloy industry are manual TIG welding, automatic TIG welding and MIG welding because of its high strength and light weight. Among them, argon arc welding is the most widely used one. However, with the development of the industry, the traditional argon arc welding has been unable to meet the increasing processing needs of users in some fields.
Traditional argon arc welding not only needs mature technicians, but also is limited by slow welding speed, difficult welding and high ozone content during welding, which is harmful to human body; The large heat affected area, easy deformation, difficult to guarantee the weld quality and other adverse factors have restricted the development of the industry.
Laser welding is a kind of welding that uses high energy density laser beam as heat source to locally heat the material in a small area and melt the material to form a specific weld pool to achieve the effect of welding. In recent years, with the continuous progress of laser technology, the application of laser processing has become more and more broad, and its advantages have become more and more obvious.
1.Fast welding speed and high processing efficiency.
2.No laser wire filling is needed to reduce the cost.
3.Reduce material deformation.
4.The weld is smooth and beautiful, reducing the subsequent grinding process.
5.The weld surface shall be formed stably without splash.
After traditional welding, it is often necessary to polish the welding points to ensure smoothness without roughness, while laser welding just reflects more advantages in processing effect. Caplin 1500W ytterbium doped fiber laser has excellent beam quality. The laser beam can be focused close to the diffraction limit, which can easily realize precision machining; There are two working modes: continuous and modulated pulse, which can greatly reduce the machining heat affected zone; Smart Bluetooth transmission, and the mobile terminal loaded with app can easily view the laser equipment.
