The application of laser welding machine technology in marking has not been long, but its development is quite rapid. The reason is that this technology is in good harmony with industrial production, and it meets the requirements of industrial production. Therefore, in the future marking industry in China, we will also see more applications of laser welding machine technology. Laser cutting machine is a machine used for laser material processing, also known as laser welding machine or laser welding machine. According to its working mode, it can be divided into laser mold welding machine (manual welding machine), automatic laser welding machine, laser spot welding machine, and fiber optic transmission laser welding machine. Light welding is the use of high-energy laser pulses to locally heat materials in small areas, and the energy of laser radiation is directed to the internal diffusion of the material through heat transfer, melting the material and forming a specific molten pool to achieve the purpose of welding. So, what are the advantages of laser cutting machine? Here are ten main advantages of laser cutting machine welding.
1. Laser welding machine: Laser welding is similar to electron beam welding in many aspects, but its welding quality is slightly inferior to electron beam welding. However, electron beam can only be transmitted in vacuum, so welding can only be carried out in vacuum. Laser welding technology can be applied in a wider range of working environments.
2. After laser focusing, the power density is high, and the high-power low order mode laser has a very small focal spot diameter after focusing,
3. The welding depth to width ratio is large, the specific energy is small, the heat affected zone is small, and the welding deformation is small. It is particularly suitable for welding precision and thermal sensitive components, and can be micro welded without the need for post weld correction and secondary processing. After focusing, the laser beam can obtain a very small spot and can be precisely positioned, which can be applied to the assembly welding of micro and small components in large-scale automated production. Not only does it greatly improve production efficiency, but it also has a small heat affected zone and pollution-free solder joints, greatly improving the quality of welding
4. It can weld parts that are difficult to access and perform non-contact long-distance welding, which has great flexibility.
5. The welding system has a high degree of flexibility and is easy to achieve automation.
6. Generally, no filler metal is added. If fully protected by inert gas, the weld seam will not be contaminated by atmospheric pollution
7. It can be welded at room temperature or under special conditions, and the welding equipment is simple.
8. It can weld refractory materials such as titanium and quartz, and can weld materials of different materials, such as copper and tantalum, which have completely different properties, together with good results.
9. It can weld parts that are difficult to access and perform non-contact long-distance welding, which has great flexibility.
10. Laser welding has fast speed, large depth, and small deformation. Due to the high power density, during laser welding, small holes are generated in the metal material, and laser energy is transmitted to the deep part of the workpiece through these holes, with less lateral diffusion. Therefore, in a single scanning process of the laser beam, the depth of material fusion is large, the welding speed is fast, and the welding area per unit time is large.
