Aluminum alloy products, as a common raw material for industrial products, play an important role in reducing body power and preventing corrosion. At present, the scope of application is very common. Especially in the automotive manufacturing industry, such as engines, wheels, dashboards, etc. Processing methods include welding and cutting. Due to the performance of laser handheld welding machine, not only the processing efficiency is improved, but also the welding effect is very good, which helps to improve the process level of the industry. The following introduces the application of laser handheld welding machine in aluminum alloy products.
Aluminum alloy laser handheld welding machine products, because the laser realizes a pulsed or continuous laser beam, the laser beam directly hits the surface of the aluminum alloy, it can quickly diffuse the heat on the metal surface of the aluminum alloy, so that the aluminum alloy melt quickly forms a weld, and at the same time forms a reaction force on the molten metal, and the molten aluminum alloy surface is concave downward to form a small hole.
Advantages of laser handheld welding machine in aluminum alloy products:
1. High energy density, low heat input, small thermal deformation, narrow melting zone and heat affected zone, and large melting depth.
2. High cooling rate, fine weld structure, and good joint performance.
3. Compared with traditional welding, laser welding does not use electrodes, which reduces manpower and costs.
4. No vacuum atmosphere is required for electron beam welding, and protective gas and protective pressure can be selected. The shape of the welded part is not affected by electromagnetics and does not generate x-rays.
5. Metal materials inside closed transparent objects can be welded.
6. The laser can be transmitted over long distances through optical fibers, and the process adaptability is good. With the cooperation of computers and manipulators, the automation and precision control of the welding process can be achieved.
The above is the application of laser handheld welding machine in aluminum alloy products. With the popularization of laser processing applications, laser handheld welding machine is used for welding aluminum alloy products, with small heat input and concentrated heat source. Especially with the emergence of optical fiber laser handheld welding machine, the energy density of laser welding is more concentrated, the laser wavelength is shorter, and the high reflectivity is improved. The use of laser wire filling,laser MIG hybrid welding and double-point laser welding can improve the forming effect and welding quality of aluminum alloy welding.
