What are the characteristics of laser welding and spot welding in Suzhou?

The characteristics of Suzhou laser welding are as follows: firstly, the deformation of the workpiece to be welded is very small, there is almost no connection gap, and the welding depth / width ratio is high. When welding high-power devices, the depth / width ratio can reach 5:1, and the highest can reach 10:1. Secondly, the weld strength is high, the welding speed is fast, the weld seam is narrow, and the surface condition is usually good, so the cleaning after welding is avoided, and the appearance is more beautiful than traditional welding. In addition, laser welding can be used to weld inaccessible parts. It has great flexibility to carry out non-contact remote welding, but laser welding can only be used for thin plates. The penetration of laser welding process is not enough, and the chassis and frame can not be welded. This point can be achieved by spot welding, but the welding joint of spot welding needs to stack two thin plates together, and there will be 15mm lamination, which not only affects the appearance, but also increases the weight of the car. Laser welding is certainly the most advanced body welding technology at present, but it is impossible for the whole vehicle to adopt laser welding. The above suggestions are for your reference only.
