What is the difference between the one-piece automobile stamping body and the multi-point welding body?
Speaking of the car body, for many people, they basically don’t know much about it. They only know some configuration and appearance of the vehicle. As far as the safety of the seat car is concerned, the body of the vehicle determines the safety level of the car and the vehicle’s own car. Heavy, of course, these are relative in terms of safety. For the car, the one-piece stamped body and the multi-point welded body, whichever is safe, no matter which one is used will basically not affect the safety of the vehicle. Of course, speaking of this, let’s understand the advantages and disadvantages and differences between them.
First of all, the one-piece automobile stamping body is relatively easy to understand, that is to say, the vehicle is basically “stamped” from front to back and from top to bottom, and there is no welding step. This is like a thing that is directly poured out through a mold, and for multi-point welding of the body, it is like building blocks, which are spliced one by one.
In terms of advantages between the two. The one-piece stamped body can save costs to a certain extent, and the process is relatively fast, and the one-piece molding has relatively high requirements on the hardware facilities of the car factory. The requirements are fully automatic, and there is no manual participation. The quality of the products is relatively balanced. The shortcomings are indeed quite obvious. In terms of energy absorption effect, it is far inferior to multi-point welding of the body. In the eyes of many people, welding is synonymous with backwardness and brittleness.
But in fact, it is precisely because of this shortcoming that it has a certain advantage for the energy absorption of the vehicle. However, it is the “shortcoming” of fragility, which causes the kinetic energy to be broken and deformed along the welding point during the transmission process, so that the Body crushing releases energy. Therefore, whether it is integrally formed or welded, it is relatively safe, but each has its own advantages depending on the material.
