With the advancement of science and technology, laser technology has become more prominent in the field of processing and manufacturing, with high efficiency and wide range. Laser welding machines have played an important role in the processing and application of precision parts. The laser welding machine is a kind of welding equipment. It is one of the welding methods that has been very popular in recent years. Laser welding uses high-energy laser pulses to locally heat a small area of the workpiece. The energy radiated by the laser is transferred to the workpiece through heat conduction. Internal diffusion melts the workpiece to form a specific molten pool. Because laser welding has a high power density and releases energy quickly, its processing efficiency is much higher than traditional welding methods. After the laser is focused, the spot is small. During the welding process, the adhesion between the two materials can be better, without causing damage or deformation on the surface of the material, and without the need for post-processing of the weld.
Laser welding is widely used in the electronics industry, especially in microelectronic precision parts. Due to the small heat-affected zone, rapid heating concentration, and low thermal stress of laser welding, it shows unique advantages in the packaging of integrated circuits and semiconductor device casings. The thickness of elastic thin-walled corrugated sheets in sensors or thermostats At 0.05-0.1mm, it is difficult to solve using traditional welding methods, TIG welding is easy to weld through, plasma stability is poor, and there are many influencing factors. However, laser welding has a good effect and is widely used.
The main advantages of precision parts laser welding machine
1. The laser for welding precision parts can be bent and transmitted through optical methods such as optical fibers and prisms. It is suitable for welding micro-parts and parts that are difficult to reach with other welding methods. It can also be welded through transparent materials.
2. It has high energy density and can achieve high-speed welding. The heat-affected zone and welding deformation are very small. It is especially suitable for the welding of heat-sensitive materials.
3. The laser used for welding precision parts is not affected by electromagnetic fields, does not produce X-rays, does not require vacuum protection, and can be used for welding large structures.
4. Insulated conductors can be welded directly without stripping off the insulation layer in advance; dissimilar materials with greatly different physical properties can also be welded.
