The application of laser welding technology in automotive manufacturing can effectively improve the accuracy and quality of welding, and plays an important role in promoting the improvement of automotive quality. Laser welding has become one of the important means in industrial manufacturing due to its advantages of high energy density, small deformation, narrow heat affected zone, high welding speed, easy implementation of automatic control, and no subsequent processing.

The most important advantage of laser welding in automotive manufacturing is reflected in the advanced non-contact processing method. Traditional processing methods such as screw fastening and adhesive connection cannot meet the requirements for precision and robustness in modern automobile manufacturing, and the application of new materials also makes traditional processing methods slightly inferior. Laser welding is non-contact, and during the processing process, laser precision welding can be achieved without touching the product. It has achieved leapfrog progress in the robustness, seamless, precision, and cleanliness of the connection, providing more possibilities for the advancement of automobiles.
