What are the characteristics of laser welding compared with traditional welding methods?

The characteristics of laser welding are as follows: firstly, the workpiece to be welded has little deformation, almost no connection gap and high depth-width ratio. When welding high-power devices, the depth-width ratio can reach 5: 1, and the highest can reach 10: 1. Secondly, the weld has high strength, fast welding speed, narrow weld and good surface condition, which saves the work of cleaning after welding. In addition, laser welding can weld inaccessible parts, and non-contact remote welding has great flexibility, but laser welding can only be used for thin plates, and the laser welding process is not deep enough to weld chassis and frame. At this time, spot welding can be carried out, but if two thin plates are stacked together at the spot welding joint, there will be an overlap of 15mm, which will not only affect the appearance but also increase the vehicle weight. Laser welding is of course the most advanced body welding technology at present, but it is impossible to use laser welding for the whole vehicle. The above suggestions are for your reference only.
