Application of laser welding in body-in-white
Body-in-white welding refers to the process of assembling stamped steel plates into a complete body structure through welding technology during the automobile manufacturing process. The body-in-white is equivalent to the skeleton of the car, and its welding quality is directly related to the overall quality and safety performance of the car.In order to adapt to the lightweight and corrosion resistance of automobiles, great changes have taken place in welding automobile materials. Traditional welding methods are difficult to meet the welding performance requirements of new automobile materials. This has given rise to laser Welding brings huge room for development.
Laser welding has many advantages such as fast welding speed, small heat-affected zone, refined weld structure, small welding deformation, general forming mechanical properties are stronger than those of the base material, and high production efficiency，Widely used in automobile manufacturing.
Solutions for body-in-white
NewFA3 brazing system
The NewFA3 brazing system has an adaptive optical system that can effectively track the weld seam during the welding process. It can also adaptively adjust the welding trajectory in the XYZ three-way according to the different deviations of different workpieces to ensure the quality of the welding.
Advantages
- Welding wire guide tracking: the welding wire tactile sensor accurately controls the tracking force, automatically compensates for the deviation of the part, and realizes the stability of the welding process
- Automatic focusing: the welding wire can follow the seam up and down, and the focus is automatically adjusted to ensure that the spot size on the welding wire is constant
