Aluminum laser welding has the following advantages compared with traditional welding:
1. Low heat input: laser welding rapidly melts the metal through a high energy density laser beam with low heat input, which can reduce thermal deformation and heat-affected zone and improve welding quality and joint performance.
2. High precision: laser welding is characterized by high precision and high speed, which can realize small melting depth, small heat-affected zone and small deformation, thus obtaining high-quality welded joints.
3. High degree of automation: laser welding can realize automation and intelligent production, improve production efficiency and product quality.
4. Environmental protection: laser welding is a non-contact welding process, avoiding the traditional welding process of smoke, noise and other pollution problems, more friendly to the environment.
5. Wide material adaptability: laser welding is suitable for welding a variety of metal materials, such as stainless steel, aluminum, copper, etc., so it has a wide range of applications in the connection of different materials.
6. Wide range of weldable material thickness: laser welding can weld materials of different thicknesses, especially suitable for welding of thin, medium and thick plates.
7. High efficiency and energy saving: laser welding process has the advantages of high efficiency and energy saving because of its small heat-affected zone, very fast heating speed and high energy utilization rate.
8. Can weld complex shapes of aluminum: laser welding can be transmitted through fiber optics to achieve long-distance welding, and at the same time can quickly and accurately adjust the position of the beam and parameters to achieve the welding of complex shapes of aluminum.
