Speaking of automobile laser welding, it can be traced back to the 1980s, when the car body was mainly welded. In the past forty years, today's laser welding production lines have appeared on a large scale in the automobile manufacturing industry and have become one of the outstanding achievements of the automobile manufacturing industry.
The automotive industry began to use laser welding technology in Germany. In the 1980s, European automobile manufacturers such as Audi, Mercedes-Benz, Volkswagen, and Volvo of Sweden took the lead in adopting laser welding of sheet metal welding of roof, body, and side frames. In the 1990s, American General Motors, Ford and Chrysler are racing to introduce laser welding into automobile manufacturing. Although they started late, they have developed rapidly. Subsequently, Italian Fiat used laser welding in the welding and assembly of most steel plate components, and Japan’s Nissan, Honda and Toyota Motor Corporation also used laser welding processes in the manufacture of body panels. Since then, high-strength steel laser welding assembly parts have been Its excellent performance is used more and more in automobile body manufacturing.
With the transformation and upgrading of my country’s manufacturing industry, the requirements of many industries for product welding quality continue to increase. Under this background, the application penetration rate of laser welding in many industries continues to rise, especially the processing and manufacturing of metal materials and parts. The rate is at a relatively high level. At present, the automobile industry is an important application market for laser welding in my country.
A car is assembled from about 20,000 parts, of which iron parts account for the vast majority. Although collectively referred to as iron, steel plates, transmissions, etc. are used to form the frame of the body frame and the body part of the model. The body part uses a casting made by melting iron and injecting it into a mold. Therefore, the welding process is an indispensable process in the automobile production and processing process, such as the frame, the body, the compartment, the engine, the automobile gear, the roof, the door, the automobile seat sliding part, the automobile airbag liner, and the Steam pipes, automobile clutches, etc. are inseparable from welding technology.
