Aluminum and aluminum alloy occupies a pivotal position in the various materials used in modern engineering technology. Its annual output in the world is second only to steel, and it ranks first in non-ferrous metals. If aluminum alloys first emerged in the aviation industry, in recent decades, in addition to the aviation industry, aluminum and aluminum alloys have been widely used in aerospace, automobiles, ships, and even home decoration.
Aluminum alloy welding refers to the welding process of aluminum alloy materials. Due to its high strength and light weight, aluminum alloys currently use manual TIG welding, automatic TIG welding and MIG welding as the main welding processes in the industry. Among them, argon arc welding is the most widely used one. However, with the development of the industry, traditional argon arc welding has been unable to meet the increasing processing needs of users in some areas.
Traditional argon arc welding not only requires mature technicians, but is also limited by the slow welding speed, the difficulty of welding, the high content of ozone generated during welding, which is harmful to the human body; the heat affected area is large, easy to deform, and the weld quality is relatively high. It is difficult to guarantee the influence of unfavorable factors, so it is subject to many constraints in the development of the industry.
Laser welding is a kind of high-energy-density laser beam as the heat source to locally heat the material in a small area, and the material is melted to form a specific molten pool to achieve the welding effect. In recent years, with the continuous advancement of laser technology, the application of laser processing has become more and more extensive, and the advantages have become more obvious.
Fast welding speed and high processing efficiency;
No need to fill wire with laser, reduce cost;
Reduce material deformation;
The welding seam is smooth and beautiful, reducing the subsequent polishing process.

After traditional welding, it is often necessary to polish the welding points to ensure smoothness and not roughness, while laser welding precisely reflects more advantages in processing effects. The Kaplan 1500W Ytterbium-doped fiber laser has excellent beam quality. The laser beam can be focused to close to the diffraction limit, which can easily realize precision processing; there are two working modes, continuous and modulated pulse, which can greatly reduce processing heat. Affected area: Smart Bluetooth transmission, mobile phone terminals loaded with APP can easily check the status of laser equipment.
