Secrets of restoring cars after serious troubles

Expensive car after a fire

Usually motorists carry out repairs of small or medium damages on their cars. In some cases, they perform restoration or replacement of individual elements of the machine. Full restoration of a car is very rare, the features of its implementation will be discussed below.

Peculiarities

Usually, the restoration of a car after an accident is carried out only if it is expedient. That is, the cost of repairing a car should not exceed its price. Therefore, cars that have been involved in small and medium-sized accidents are usually restored. Before starting work, the machine is inspected and their cost is estimated. Full restoration is relevant for rare or rare models. Such cars are repaired even after major accidents or fires, as well as restored.

In most cases, the restoration or restoration of a car is characterized by high cost, great complexity and duration of work.

The high price is explained by the corresponding price of parts for most rare and rare cars. Duration is determined by the complexity and volume of work. In addition, it may be difficult to find rare parts. The complexity is due to the fact that as a result of major accidents, the geometry of the body is often violated, and after a fire, depending on the strength, it is necessary to lay wiring, re-tighten the interior, repair or change the engine.

The complexity of the restoration is determined by the condition of the car. The main type of damage, unlike broken cars, in this case is corrosion. It can render unusable all hinged body parts and even damage structural elements.

It is possible to purchase a car from scrap. Moreover, among the broken copies and cars after a fire from scrap, you can find options in very good condition at a low price, since the reasons for the disposal of cars are different, and this is not always due to functional unsuitability. However, the main problem of a car from scrap is not repair, but registration. On the network you can find articles and videos on the purchase of cars from scrap:

Sequence of work

Restoration of cars after a major accident or fire, like restoration, affects most or all elements and components, therefore, it includes many stages, the sequence of which is discussed below.

  • The first of these is a complete disassembly of the car. This allows, having fully examined it, to identify whole and non-original parts and, on the basis of this, determine the areas of work, a list of parts and materials and evaluate the repair. In this case, drawings, maintenance and repair instructions and other literature, technical documentation and videos are used.
  • After disassembly, the body is cleaned of paintwork and corrosion using various methods and abrasive materials.
  • At the next stage, body elements are changed or restored. In this case, welding is often used. The method is chosen based on the material. There are metal, aluminum and fiberglass body parts. The metal is usually welded by the electrode method, although other technologies are sometimes used, but only argon welding is suitable for aluminum, since if other methods are used, an oxide film forms on it. This method requires professional skills, good equipment and high-quality consumables. Welding technology can be studied from articles and videos. Parts with minor damage are restored by local repair. In the absence of any part on the market, you can order its production.
  • Next, restore the frame. This stage is relevant only for cars with a frame body structure. On such models, the frame forms the basis of the body, since all units are attached to it, that is, the suspension, engine, transmission. The frame is sandblasted first. This allows you to detect defects that are invisible during the initial inspection, such as microcracks, as well as deformation damage in the form of transverse and longitudinal bends. An additional verification method is to check the frame dimensions with factory data. Mechanical damage to the frame is usually typical only for badly beaten cars, however, this element can be corroded or destroyed due to metal fatigue. When restoring, metal fatigue must also be taken into account.
  • Further, all components and assemblies of the car are repaired (suspension, transmission, engine, brake system, etc.). These works should be considered as separate stages.
  • Upon completion of the repair, the car is painted. Galvanic work, that is, chrome plating of parts, can also be attributed to this stage. The technology of their preparation is the same as for painted body elements. That is, you need to clean them from the old coating and corrosion. Damage must be sanded and polished. You can study the technology of painting and galvanic works on articles and videos.

The volume of restoration work of the salon is also determined by its condition. After an accident, usually only the airbags and their coverings are replaced, while as a result of a fire or wear and tear, the interior can be completely destroyed, and it will require a complete replacement. It's easier to buy new seats than to re-tighten them. However, some work, such as ceiling hauling, will still have to be done manually. On the network you can find articles and videos describing these works.

Typically, interior restoration is combined with wiring replacement, which is also likely to be required after a fire. In any case, you should check its condition. Wiring replacement is one of the most difficult types of car repair work, especially for modern models equipped with many electronic systems. Therefore, it is advisable to entrust them to professionals, or you will have to find a car wiring diagram, as well as manuals, videos.
