Laser welding for precision instrument applications

Laser welding is one of the important aspects of the application of laser material processing technology. It is mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conductive, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through thermal conduction. By controlling the laser pulse Parameters such as width, energy, peak power and repetition frequency cause the workpiece to melt and form a specific molten pool. Due to its unique advantages, it has been successfully used in the welding of micro and small parts.

Compared with other traditional welding technologies, the main advantages of laser welding are:

1. Fast speed, large depth and small deformation.
2. It can be welded at room temperature or under special conditions, and the welding equipment is simple to install. For example, when a laser passes through an electromagnetic field, the beam will not deflect; the laser can be welded in vacuum, air and certain gas environments, and can be welded through glass or materials that are transparent to the beam.
3. It can weld refractory materials such as titanium, quartz, etc., and can also weld heterogeneous materials with good results.
4. After the laser is focused, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1 and up to 10:1.
5. Micro welding is possible. The laser beam can obtain a very small spot after being focused and can be positioned accurately. It can be used in the assembly welding of micro and small workpieces produced in large quantities for automated production.
6. The weld is smooth and beautiful, and no treatment is required or only simple treatment is required after welding.
7. The weld is of high quality and has no pores, which can reduce and optimize the base metal. The structure can be refined after welding. The strength and toughness of the weld are at least equal to or even exceed that of the base metal.
8. It can weld inaccessible parts and implement non-contact long-distance welding, which has great flexibility. Especially in recent years, optical fiber transmission technology has been adopted in YAG laser processing technology, making laser welding technology more widely promoted and applied.
9. The laser beam can easily split the beam according to time and space, and can perform multi-beam simultaneous processing and multi-station processing, providing conditions for more precise welding.

Fiber transmission laser welding machine is a type of laser welding equipment that couples a high-energy laser beam into an optical fiber. After long-distance transmission, it is collimated into parallel light through a collimating mirror, and then focused on the workpiece for welding. For parts that are difficult to access for welding, flexible transmission and non-contact welding are implemented to provide greater flexibility. The laser beam of the optical fiber transmission laser welding machine can achieve light splitting in time and energy, and can process multiple beams at the same time, providing conditions for more precise welding. The optical fiber transmission welding machine has the advantages of good beam quality, fine spot, and flexible installation. Suitable for precision welding of optical communication devices, IT, medical, electronics, batteries, optical fiber coupling devices, picture tube electron guns, metal parts, mobile phone vibration motors, watch precision parts, automobile steel sheets, etc.
