Application of laser gas mixture in automobile manufacture

In the automobile industry, laser technology is mainly used for tailoring welding, welding and parts welding. Laser Tailor Welding is in the body design and manufacturing, according to the different design and performance requirements of the body, the selection of different specifications of steel plate, through laser cutting and assembly technology to complete the body of a part of the manufacturing, such as front windglass frame, door plate, body bottom plate, central column, etc. Tailor laser welding has been adopted by many major automobile manufacturers and parts suppliers for the benefits of reducing the number of parts and molds, reducing the number of spot welds, optimizing the amount of materials used, reducing the weight of parts, reducing costs and improving dimensional accuracy. Laser welding is mainly used for the welding of body frame structure, such as the top cover and side body welding. With laser welding technology, the width of the joint between the workpiece joints can be reduced, reducing the use of plates and improving the stiffness of the car body. Laser welding parts, parts of the welding site almost no deformation, welding speed, and do not need post-welding heat treatment.
