Laser welding is one of the fastest-growing welding methods in modern times, one of which is the laser welding machine. So how is laser welding achieved? Laser welding uses high-energy laser pulses to locally heat a small area of the workpiece. The energy of the laser radiation diffuses into the interior of the workpiece through heat conduction, melting the workpiece to form a specific molten pool. Laser welding has high power density and releases energy quickly, so it is much more efficient than previous welding methods. After the laser is focused, the spot is very small. During the welding process, the viscosity between the two materials can be better, the surface of the material will not be damaged or deformed, and there is no need for post-processing of the weld.
As one of the earliest manufacturers of laser welding equipment in China, Guangzhou Laisai Laser Company has nearly ten years of R&D and production experience, and is in a leading position in the industry in terms of technology and integration. Since its establishment, the company has always paid attention to the research and development of laser technology and the development needs of customers, and is committed to providing every customer with complete laser welding processing solutions.
Laser welding is widely used in the electronics industry, especially in microelectronic precision parts. Due to the small heat-affected zone, fast heating concentration and low thermal stress of laser welding, it shows unique advantages in the packaging of integrated circuits and semiconductor device shells. The thickness of the elastic thin-walled corrugated sheet in the sensor or temperature controller is 0.05-0.1 mm, which is difficult to solve by traditional welding methods. TIG welding is easy to weld, but the plasma stability is poor and there are many influencing factors. Laser welding has good effect and is widely used.
What are the advantages of laser welding for precision parts:
1. The laser used for precision parts welding can be bent and transmitted through optical methods such as optical fiber and prism, which is suitable for micro parts and other parts that are difficult to reach by other welding methods, and can also be welded with transparent materials.
2. High energy density, high-speed welding can be achieved, heat-affected zone and welding deformation are very small, especially suitable for welding heat-sensitive materials.
3. The laser used for precision parts welding is not affected by electromagnetic fields, does not generate X-rays, does not require vacuum protection, and can be used for welding large structures.
4. Insulated conductors can be directly welded without stripping the insulation layer in advance; dissimilar materials with large differences in physical properties can also be welded.
