What are the advantages of applying laser technology to railway track industry

With the rapid development of the world economy and the accelerating pace of people's life, the increasingly fast mode of transportation has become an urgent need of people. Railway is closely related to people's daily life. It is one of the important components of transportation hub. It is an important national infrastructure, which is directly related to people's vital interests.

In order to effectively improve the operation efficiency of the railway, the railway development is mainly towards the direction of high-speed passenger cars, subway passenger cars, light rail vehicles, high-speed heavy haul trucks, etc. in order to realize these needs, the train must be lightweight. It is now a common practice to use aluminum alloy materials in the manufacturing process of passenger cars. Because aluminum alloy materials have the characteristics of light weight, corrosion resistance, smooth appearance, complex curved surface and high specific strength, they can effectively reduce the resistance and mass of passenger cars and increase heavy load. In order to effectively improve the processing efficiency of aluminum alloy materials and ensure the safety of passenger cars, it is necessary to change the traditional processing mode and use laser technology for processing and manufacturing.

At present, the application fields of laser technology in railway passenger car manufacturing are mainly plate and profile blanking, key component welding, automatic production line material transportation and identification transplantation. It has the characteristics of fast processing speed, small workpiece deformation, high precision and material saving. Using the current laser technology for processing can not only effectively ensure the firmness of the rail train, but also use computer control to effectively control the yield of the processed workpiece. In addition, the surface of the processed workpiece will not be lost in the processing process. The appearance is exquisite, and different sizes can be accurately controlled. Laser cutting machines, laser welding machines, laser marking machines and optical fiber laser marking machines are widely used in the railway processing industry. With the continuous change of the demand for rail trains, different types of rail trains with different needs are developing. In order to meet these diversified processing needs, it is necessary to adopt the current high salary processing method for processing and manufacturing, The application of laser technology is one of them.

It is believed that in the near future, rail trains will make people's travel more convenient, safe and efficient, and the application of laser technology in rail train manufacturing industry will be closer.
