How to repair the aluminum alloy car body depression? If the door is all aluminum, it is definitely not good. Although the advantage of aluminum is light, it is easily deformed. Ordinary cars are made of aluminum alloy. How to repair the aluminum alloy body depression? Let's share it below.

How to repair the aluminum alloy car body depression 1 aluminum alloy car body repair needs car repair agent and sponge. The specific operation is as follows:

1. First, the aluminum alloy car shell is damaged, check the specific location;

2. Squeeze the car repair agent on the sponge and then spread it evenly;

3. Apply the damaged parts forcibly until the damaged parts disappear;

4. Then spray the paint with the same color as your car on the repair part and spray it evenly;

5. It is best to gently touch the repaired damage with your palm to see if it is smooth.

Repair of appearance of aluminum alloy car body

Repair of mild depression

The slight dent in the appearance of aluminum alloy car body mainly means that there is an elastic dent less than 2mm on a large plane of the car body. After the car body is repaired, it has little influence on the car body paint, and the effect after repair is good, the repair price is low, and there is no adverse effect on the car body. When repairing minor dents, first clean the dents with detergent and cleaning cloth, observe the dents and carry out the next repair work. Then remove the interior decoration that hinders the repair inside the car body, and then push it out from the inside of the car body with a crowbar, and ensure that the crowbar is evenly applied and operated repeatedly. At this time, use the strip lamp to illuminate, observe the situation of the depression, and stop the operation of the crowbar until the depression is completely repaired. Wait for a few minutes, and the whole repair work is completed after the repair area is stable and no longer deformed.

Repair of systemic depression

Repairing general dents requires removing car paint and car film from the car surface, which is also complicated and expensive and will affect the quality of the original factory. When repairing general depressions, it is also necessary to clean the car body first to find out the areas that need to be repaired. Then use a grinder to polish the concave place to let the bottom of the car leak out.

Before concave drawing, it is necessary to heat the car body with a flame gun to soften the aluminum alloy car body and draw it better. In addition, when heating, it is necessary to stick temperature indicating stickers around to prevent the body from being damaged by excessive heating temperature. Wire drawing can be carried out after the depression is softened, and tapping can be carried out at the same time of wire drawing. After the dent is repaired, use a file and grinder to polish and smooth it. If the repair effect is not good, you can continue to repeat the above work until the repair is completed. Finally, the painting work outside the car body can be handed over to the repairman for painting treatment.

Repair of severe depression

The repair of serious depression is mainly carried out by cutting and welding, and also involves riveting and bonding. The repair of serious dents generally requires consulting the vehicle maintenance manual, and parts need to be replaced in severely damaged parts, which should be purchased according to the parts model in the vehicle maintenance manual. Before riveting and bonding, it is also necessary to consult the vehicle maintenance manual to ensure that the cutting position is cut correctly before riveting and bonding. After riveting and bonding, it needs polishing. After polishing, it will be handed over to the painter for painting.

How to repair the aluminum alloy car body depression II. How to repair the depression of aluminum alloy car door?

All aluminum doors can be repaired, but the damage should not be too great. For example, if aluminum itself is not hard enough, it may crack a hole. This situation can only be replaced and cannot be repaired. Generally speaking, it is best to go to a 4s shop for maintenance, because the technology of the 4s shop is better, and the maintenance master in the outside repair shop may not be able to recover, or the recovery effect is not good, and it is easy to paint off or repair from the surface energy.

Generally, it can only be repaired by a slight collision. Aluminum can only be repaired by knocking the wound surface as slowly as possible, or using a toilet plug to coat vaseline seams and pull it out in a sunken position. Generally, it can only be used on door panels.

The advantage of using aluminum in automobiles is that it can have good ductility, and it can be combined with many other materials to synthesize metal, and the material quality is high, such as aluminum alloy. The most important thing is to reduce the weight of the car and improve the handling performance.

The right tools

Because iron and aluminum will react chemically under certain conditions, which will accelerate corrosion, it is necessary to avoid confusion with tools for repairing steel car bodies, because the possible residual iron chips will react chemically with car bodies and accelerate corrosion.

There should be a separate maintenance space.

In order to ensure the safety of automobile maintenance and operation, there should be independent maintenance space to avoid cross-contamination and explosion danger. At the same time, maintenance personnel should also master certain professional skills, such as cutting and welding with the car body, to ensure the smooth progress of maintenance work.

Whether it is a traditional car or a new energy car, the reduction of quality means the saving of resources. Aluminum alloy fuselage has been popularized, and the corresponding technology must keep up. There is a great difference between steel body and aluminum alloy body. So it will take some time to popularize it.

Now is the primary stage of aluminum alloy development, of course, we can't miss this opportunity. In the rapid development of the automobile market, we constantly innovate and develop more new technologies that are more suitable for the market and the public!
