What are the differences, advantages and disadvantages between one-piece stamping body and multi-point welding body?
Speaking of the car body, many people don't know much about it. They only know some configuration and appearance of the car. As part of the safety of the seat car, the car body determines the safety degree of the car and its own weight.
Speaking of the car body, many people don't know much about it. They only know some configuration and appearance of the car. As part of the safety of the seat car, the car body determines the safety degree of the car and its own weight. Of course, in terms of safety, these are relative. For the car, what kind of safety is the integrated stamping body or the multi-point welding body, No matter which one is adopted, it will basically not affect the safety of the vehicle. Of course, speaking of this, let's understand the advantages, disadvantages and differences between them.
First of all, it is easier to understand the integrated stamping body, that is, the vehicle is basically "stamped" from front to back and from top to bottom, without welding steps. This is like a thing directly inverted through a mold, and the multi-point welding body is like building blocks, which are spliced one by one.
In terms of the advantages between the two. The integrated stamping body can save costs to a certain extent, and the process is relatively fast. Moreover, the integrated forming has high requirements for the hardware facilities and supporting facilities of the car factory. The requirements are fully automatic and there is no manual participation. Therefore, the voice quality of such products is relatively balanced. The disadvantages are obvious indeed. The energy absorption effect is far inferior to that of multi-point welding. Welding is synonymous with backwardness and fragility in the eyes of many people.
But in fact, it is precisely because of this disadvantage that it has a certain advantage for the energy absorption of the vehicle. However, it is the "disadvantage" of fragility, which makes the kinetic energy break and deform along the solder joint in the transmission process, so as to break the body and release energy. Therefore, whether it is integrally formed or welded, it is relatively safe, but it has its own advantages according to different materials.
