Is it hard to repair car sheet metal? How long does it take for a car sheet metal to be repaired

Learning auto sheet metal work is difficult to say, not difficult, not difficult. Why? Listen to me explain:

1. Automobile sheet metal workers have a certain knowledge of three-dimensional geometry, because the work is basically combined with plane geometry and three-dimensional geometry for maintenance, and the calculation is accurate, so that the products you make can make various angles, arcs, planes, or the combination between them is the same as the original car. If you have that knowledge, it's not hard, right?

2. To learn automobile sheet metal work, you must have patience, many jobs are hammered out, and you can't rush it, otherwise some parts will swell up, and it will collapse. For example, if the fender is broken, you need to saw it, and the more you saw, the smaller the strips, the better it will be to restore the original shape. If you're afraid of trouble, it's hard to learn auto sheet metal work, right?

Hope it helps, thank you.

It mainly depends on what kind of damage it is, if it is just a small pit and a small packet, it is easier to repair, if it is a dead fold or a puncture wound, it is too difficult to repair.

1. Impact bump damage. The impact bumps of sheet metal parts can be repaired by hammering or jacking. Different approaches are used for the same situation. Of course, the process flow is not the same if the degree of concave and convex is different, and the problem of body material must also be considered!

2. Warping, skewed deformation. Sheet metal parts due to impact, friction or improper use will produce warping, skew and other deformations, at this time can be eliminated by mechanical methods or by the method of flame heating and knocking.

3. Broken or perforated. The surface of the perforated sheet metal parts of the impact damaged goods can be repaired by applying the adhesive method, and the adhesives currently used mainly include epoxy resin glue, phenolic resin glue and copper oxide binder.

Fourth, cracks or local serious damage. For these two cases, in the past, the method of welding repair or repair would be adopted in automobile repair, but at present, 4S shops usually directly adopt replacement treatment.

Automobile sheet metal painting takes a day to repair: 1. Sheet metal painting is a kind of automobile repair technology, which is to repair the deformed part of the metal shell of the car, such as the shell of the car body is hit by a pit, you can restore it to its original state through sheet metal, and then restore the deformed metal surface of the car to the same as other intact places by spraying special paint, as bright as ever; 2. After the car body is corrected by sheet metal, there are some defects that can not be made up for by sheet metal work, even if it is replaced with new parts, there will be imperfections, in order to achieve more perfect precision, it is necessary to make up for the defects with the process of sculpture, after the car is damaged by deformation and other reasons, its flatness, wheel angle and line, each part needs to be filled with scraping ash to grind out; 3. Our repair of the body skin is the same as repairing the mold, so our scraping and shaping process should be coherent with the mold processing, which is a job that ordinary painters cannot do, and many painters who have worked for many years will sigh a sentence.

According to the technology, the sheet metal time is generally not a small deformation can be done within half an hour, but after the sheet metal, it will take at least two to three days to spray paint and bake.

Automobile sheet metal is a processing method for automobile maintenance, also known as cold work, to say that directly, if the appearance of the body is damaged and deformed, the process of sheet metal is needed. Automobile collision repair has developed from the original "smashing, pulling and welding repair" to the secondary manufacturing assembly of the body.

Hello, dear! When the car is painted sheet metal, it takes about 5 or 6 days to complete, and when implementing sheet metal repair and car paint repair, you must go to a professional store, and you must not be greedy for cheap to go to some stores with poor technology. First, the body paint of the car I think is very complicated, the body paint is composed of four layers, from the inside to the outside are the electrophoresis layer, the middle coat, the color paint layer, and the varnish layer.

Second, the function of the swimming layer is anti-rust, after the whole body is assembled, the whole body will be soaked into the electric pool, so that the entire body surface can form an electrophoresis layer. Third, on top of the electrophoretic layer is the middle coating, the key role of the middle coating is also anti-rust, but also can improve the ability to combine with the next layer of body paint.

Fourth, on top of the middle coating is the color paint layer, and the color paint layer plays a key role in aesthetics. The various body paints that we can usually see are presented by the color paint layer. Fifth, the outermost layer of paint is the varnish layer, and the varnish layer plays a key role in ensuring the color paint layer, and can also improve the gloss of the body paint.

Sixth, the varnish layer is the most vulnerable layer of body paint, usually most of the small scratches are basically left on the varnish layer, and the scratches on the varnish layer can be removed by polishing, but it is not recommended that friends often polish.

This needs to depend on how big you need to repair here, if it is very small, it may be completed in one to two hours, if it is large, it needs to be sprayed gold in the later stage, and it takes two to three days to spray paint today, followed by whether there is more work in the store, if it is more, it may take more days.

This depends on the degree of damage to the car, and how much work the repair shop master does, if the repair has already started, then solve the problem within an hour or two! After that, the time for spraying paint will be another story!

If you are bare sheet metal, it should take 3-5 hours quickly, and if you paint it, it will take longer, and you need to wait for the paint to dry! This depends on the damage area of your car, generally the front and rear bars are 300, the horizontal bars are 150, and the doors are generally 200

Depending on the extent of the impact on the vehicle, large areas take a week to repair and paint up to three days:

This depends on the difficulty and area of the repair, the more difficult and the larger, the longer the repair time.

This is completely judged according to the size of the damage area and the difficulty of repair, some small pits may only take a few minutes, and large sheet metal accidents can take several days.

The living conditions are getting better and better, every household has bought a car, but in daily life, the car is inevitably bumped and bumped on the road, especially for the reversing technology is not good, the car is always potholes, plus the weather in recent years is also relatively large, the billboard that flew down was accidentally hit by a falling object when parking, which made the owner feel distressed, but there was no injury to the body frame, in fact, it was only slightly deformed, and it only needed to be restored through sheet metal. <>

1. What is sheet metal?

The so-called sheet metal is actually a processing technology, so far sheet metal has not given a complete definition, in some foreign journals, sheet metal will be defined as the processing technology of metal sheets, including various processing techniques, the salient feature is to let.

Finally, the sheet metal becomes uniform in thickness and shape.

2. How to repair automobile sheet metal?

The so-called automobile sheet metal is a technical means for the repair of metal plates on the surface of the car, through sheet metal repair, the car can be repaired after the collision, or the dent caused by the accident, not only can the body anti-corrosion and decoration be sprayed, but also the whole body can be shaped, stretched, corrected, stressed welding or the assembly and adjustment of body accessories. It is mainly through the force of personnel and machinery and equipment to restore the deformed position of the metal plate to its original shape.

3. What are the steps of auto sheet metal?

In the case of automobile sheet metal, first of all, the vehicle collision or accident is caused, the repair part needs to be marked, the deformation is observed, the damage is determined, the tools used in the process of sheet metal and the appearance of the vehicle are damaged, whether the repair can not be disassembled and restored, or whether the maintenance part has cracks or even signs of fracture, if there are cracks or fractures will be replaced, try not to repair, after determining the repair part, it is necessary to refer to the technical parameters and dimensions of the body. According to the characteristics of the body material, the force characteristics and the direction of the deformation force, the body is stretched and flattened and welded, and on this basis, it is not only based on advanced work experience, but also through accurate instruments to judge. After the body is restored to its original shape, the damaged paint surface is further processed, sprayed with color paint, and finally the body is restored to its original shape and appearance.

It can be seen from the above aspects that the steps of automobile sheet metal are to first determine the maintenance part, and then restore the damaged part of the dent part according to the measurement data, and then carry out color painting and adjust the paint surface after recovery.

Automobile sheet metal painting is divided into 3 steps:

1. The first primer fills the sand marks and micropores at the bottom of the workpiece, increases the adhesion of the lower coating, and also has the effect of defect indication.

2. The primer is a very important part of the coating, which prepares a complete and smooth working surface for the topcoat, completes the last process of all primer work, increases the adhesion of the intervening layer and has a certain isolation effect, so as to ensure the quality stability of the topcoat.

3. Topcoat, topcoat is divided into single-layer paint and multi-layer paint, which is the color determination layer and decorative protective layer. Multi-layer paint is divided into silver powder series paint and pearl series paint, which is divided into double-layer and multi-layer construction process to complete the paint, and silver powder paint is made of special aluminum materials.

Extended information: In the painting process, the treatment of the surface of the car body that needs to be repaired is very important, if the treatment is not good, not only the surface feels rough and uneven, but also brings repair, which directly affects the satisfaction of the car owners with the service.

As an important process in sheet metal spray maintenance, the traditional wet grinding process was used for surface treatment in the past, and the quality hazards brought by this process method are increasingly exposed.

The grinding method of pneumatic tools or electric tools used in the "dry grinding" can not only effectively absorb the dust generated in the maintenance, but also improve the maintenance efficiency and ensure the effect.

The main process of sheet metal work: The main process of sheet metal work can be roughly divided into:

1: Body disassembly.

2: Body correction.

3: Body restoration.

Each of these processes can be subdivided into several processes. There are two concepts that must be covered in the in-depth explanation.

1: Automobile trade.

2: Car body.

1: The automobile repair industry can be basically divided into mechanical repairers, electrical repairers, sheet metal repairers, painting repairers, and other accessories, beauty, and special repair industries are not included.

The division of the car body means to remove the whole car circuit computer system, remove the whole car engine drive, brake steering system, and remove the car paint. Then all that remains is the body of the car.

2: The body assembly (this is a generic accessory name) includes: body sheet metal parts (metal parts) car glass, the whole car lamps, the whole car, exterior decoration parts and handles, seats and accessories, lock mechanism, window sealing and lifting mechanism, door and front and rear sail cover connection mechanism, the sum.

In other words, when your car has problems such as broken glass, door lock failure, damaged trim, etc., remember that you need to find the car sheet metal and not other types of work!

Since the car is a high-precision whole. And electrical accessories and mechanical accessories should be attached to the corresponding position of the car body with high precision and low error. Even the straightness and curviness of the paint (which greatly affects the appearance of the body) are highly dependent on the error value of the body sheet metal, so the sheet metal body and repair have become a pure manual work that has no hard standards, no automatic tools, and cannot be intuitively taught in the automotive industry.

In short, car sheet metal is the complete repair of a faulty and damaged car body!

1.Restoration of the front hood.

The repair of the front cover is relatively simple, and it can be repaired by removing the insulation layer or scraping off the adhesion or punching holes according to the situation.

2.Restoration of the front fenders.

The front fender can be repaired by removing the headlights, the fenders on the tires, and the small side lights. It is also possible to repair the pores at the rear end of the front fenders, and in some cases it is permissible to remove the fixing screws on the upper part of the front fenders and then use triangles to support the voids for repair.

3.Restoration of the roof.

When repairing the roof, according to the dent situation, the roof interior can be removed completely or only part of the interior buckle can be removed, the principle is that the tool can be reached and unobstructed, and the disassembly can be minimized.

Summary. Hello dear, the car sheet metal repair is good

Generally speaking, after the vehicle is collided, it is possible to do sheet metal painting, what is possible? Because judging whether to do sheet metal painting, it is very simple, that is, whether the body has serious dents and paint loss. Sheet metal is the place where the vehicle collides and deforms, and repairs it.

Painting is the restoration of the color and gloss of the vehicle after it has been restored to the state it was in before the collision.

How long can the quality be maintained after the sheet metal is repaired.

Dear, generally speaking, if it is repaired, it will be the same as before When selling a car, it is less depreciating than changing it.

Dear, after the car sheet metal painting, if the later maintenance is good, it can be maintained for 6 years.

Which is better, a sheet metal repair shop or a 4S shop.

Dear, 4s is a little better.

It's good to change the door of the original factory.

I was touched on the door.

Dear, we change the overall depreciation of the car in the future, and it is not seriously recommended not to change.

Dear, there is no difference between the original factory and the auxiliary factory, and this accessory is not a key part. However, the depreciation of the car is less when it is changed to the original manufacturer.

I'll take a **, can you help me see if this is serious?

OK. Send me a private message.
