As a common raw material for industrial products, aluminum alloy products are important for reducing the power of the car body and preventing corrosion, etc., and are now widely used. Especially in automobile manufacturing, such as engines, rims, dashboards, etc. The processing methods include welding and cutting. Due to the outstanding performance of the laser welding machine, not only the processing efficiency is improved, but also the welding effect is very good, which helps to improve the technological level of the industry.
1. Application of laser welding machine on aluminum alloy products
Because the laser beam is realized by pulse or continuous laser beam, when the laser beam directly irradiates the surface of the aluminum alloy, the heat on the metal surface can be quickly diffused to the interior of the aluminum alloy, making the aluminum alloy The rapid melting forms a weld, and at the same time creates a reaction force on the molten metal that dents the surface of the molten aluminum alloy downwards to form small holes.
Ⅱ. The application advantages of laser 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 penetration depth;
2. The cooling rate is high to obtain fine weld structure, and the joint performance is good;
3. Compared with traditional welding, laser welding does not use electrodes, so it reduces working hours and costs;
4. There is no need for a vacuum atmosphere during electron beam welding, and the shielding gas and pressure can be selected. The shape of the workpiece to be welded is not affected by electromagnetic waves and does not generate X-rays;
5. It can weld the metal material inside the airtight transparent object;
6. The laser can be transmitted by optical fiber for long-distance transmission, so that the process adaptability is good, and the automation and precise control of the welding process can be realized by cooperating with the computer and the manipulator.
The above is the application of laser welding machines on aluminum alloy products. With the improvement of the popularization level of laser processing applications, laser welding machines are used to weld aluminum alloy products. The heat input is small and the heat source is concentrated, especially after the advent of fiber laser welding machines, the energy density of laser welding is more concentrated, the laser wavelength is shorter, and the high reflection is improved. Through laser wire filling, laser-MIG hybrid welding, double-spot laser welding and other processes, the forming effect of aluminum alloy welding can be significantly improved, and the welding quality can be improved.
