First, the manufacturing industry:
Today's automotive manufacturing is becoming more demanding and sophisticated for automotive steel sheets. Some conventional welding techniques are not sufficient. However, after the emergence of automation, it has met this strict requirement of the automobile manufacturing industry and has become a common processing technology in the global automobile manufacturing industry, and has made great contributions to improving the strength of automobile parts and improving the processing efficiency. At the same time, automated laser welding equipment brings high-quality effects in the manufacture of gears to improve accuracy and enhance service life, and microwave ovens (lifting sealing effect).
Second, the electronics industry:
The most popular laser welding is now widely used in the electronics industry. Laser welding technology has a unique advantage in semiconductor and integrated circuit packaging due to its rapid heating concentration and low thermal response, which plays an important role in ensuring high precision and high density of electronic products.
Third, the area of powder no cure:
It is well known that the brazing method commonly used in the connection of powder metallurgy materials is limited in application of powder metallurgy due to the low bonding strength and wide heat-affected zone width, which makes it impossible to adapt to high temperature and high strength. Laser welding compensates for this deficiency by virtue of its large depth ratio and narrow weld seam, which improves the strength of welding and high temperature resistance, bringing new life to the application of powder metallurgy materials.
What are the applications of laser welding automation equipment? Many people have asked me this way. The above is the introduction of several fields in which laser welding uses automation equipment. Because welding has a wide range of applications in many fields, it has opened up a broad prospect for the production of modern laser welding equipment. Therefore, the use of laser welding has become the main choice of welding.
Laser welding is to radiate a high-intensity laser beam to a metal surface, and the metal is melted to form a weld by the interaction of the light and the metal. Laser welding equipment has been widely used in the manufacturing and automotive industries, and the number of companies using laser welding equipment on the market is still increasing, mainly due to several advantages of laser welding:

1. The welding speed is fast, the depth is large, and the deformation is small.
2, the device is simple, the application environment is low, and it can be welded at room temperature or under special conditions. The laser passes through the electromagnetic field, and the beam does not shift. The laser can be welded in vacuum, air, and a certain gas environment, and can be welded through glass or a material transparent to the beam.
3, a wide range of applications, can be welded refractory materials such as titanium, quartz, etc., and can weld the opposite material, the effect is good. And the welding equipment can be micro-welded, which can be applied to the group welding of micro- and small-sized workpieces produced by large quantities.
4. The welding degree is large. After laser focusing, the power density is high. When welding high-power devices, the aspect ratio can reach 5:1 and the maximum can reach 10:1.
6, can be welded to the proximity of the site, the implementation of non-contact long-distance welding, with great flexibility. Especially in recent years, the optical fiber transmission technology has been adopted in the VAG laser processing technology, which has made the welding and soldering technology more widely popularized and applied.
However, there are some caveats to the app:
1. Laser welding requires high precision assembly of the weldment and requires that the position of the beam on the workpiece cannot be significantly offset. This is because the spot size of the spot after the laser is concentrated is small, and the weld is narrow, and the metal material is filled. If the workpiece assembly accuracy or beam positioning accuracy does not meet the requirements, it is easy to cause soldering sensation.
2. In the process of interaction between laser and metal, in order to achieve good fusion welding, it is necessary to melt the metal into the main form of energy conversion, rather than in other forms such as vaporization and plasma formation. This requires the use of laser welding equipment to understand the various physical phenomena generated by the interaction between laser and metal and the relationship between these physical phenomena and laser parameters to achieve the purpose of ideal welding.
