In most cases, when an automobile has an accident, the body surface panel will be deformed or directly damaged. If it is damaged, such as the bumper is torn, it must be replaced. But in some cases, there is only deformation, and this deformation is not too big or too small, so there are two options for maintenance, plastic or replacement. As we all know, it is not the original car after replacement, and the quality is definitely not as good as the original car. If it is not replaced, it will only be painted, and the owner is worried about strength and durability, so the choice of maintenance method is very tangled. Today, let's talk about when to replace it. Under what circumstances, only maintenance can be done.

For all parts that can be replaced separately, replacement is better than maintenance in most cases. For parts that cannot be replaced separately, whether they need to be replaced depends on the degree of deformation and whether they can be repaired. It is best not to replace it easily. What is an accessory that can be replaced separately? It is not a whole with the car body, but is installed on the car body and can be replaced separately. The most prone to accidents are front and rear bumpers, front fenders, doors, hoods, water tanks and so on.

On the contrary, it is a whole with the car body, that is, parts that cannot be replaced separately. If you want to replace them, you have to replace the whole body, which is obviously irreplaceable. Maintenance methods are cutting and welding. This place is seriously deformed. Cut this severely deformed place, and then cut a piece from the same part of the new body to weld the accident car. There are many accidents, such as rear fender, under the threshold, B-pillar and door frame. These places are deformed. If replacement is needed, cut out the deformed places, and then cut out the same places from the new car body before welding. This newly cut car body is not a complete car body, but a whole side of the car body, which is very long and big from front to back, including all the places mentioned above, where to cut.

As can be seen from the maintenance method, cutting and welding method is harmful to the car. After welding, it is not an integral structure with the original car, and the strength of the car body will inevitably decrease. So, all these places are injured. If the deformation is slight, even if it is the responsibility of the other party, the other party will compensate and try not to replace it. Plastic painting will do. If the deformation area is relatively large and deep, or it is technically beyond repair, it must be replaced. Because the deformation is too large, even if it is reshaped, the strength here is reduced because the metal is bent a lot, which may not be as good as replacement.
