Body repair services provided by professional workshops expensive. Therefore, the question of the independent execution of these works is relevant. Then the body's body repair is discussed with their own hands.
Requirements
For independent carrying out bodywork, premises and equipment are necessary. The requirements for these conditions are determined by the peculiarities of the repair. For one-time work, it is necessary to equip the room (usually a garage) lighting. It is necessary to establish both stationary and portable lighting devices, competently by placing them to ensure good visibility of the car on all sides. As for equipment and materials, their choice is determined by the type body repair.
The highest requirements in case it is planned to carry out work regularly. Then the garage should not only be illuminated, but also insulated to ensure the possibility of repairing the repair in the cold period. In addition, you should purchase a device for restoring the body geometry. It should be borne in mind that the cost of the corporate instrument is high, but you can also purchase a homemade analogue.
A variety of tools will also need to perform various repair operations, while you are mandatory straight hammers and a welding machine.
You can purchase them as sets and separately. In any case, it is better to choose as many versatile equipment as possible. This will reduce the total number of tools using each of them to perform various works.
For the implementation of particularly complex repair work At a high level, such equipment is needed as laser tools for control of body geometry and ultrasonic flaw detection apparatus. However, if it is planned to make a small body repair with your own hands, to acquire so expensive equipment inexpediently. Even with a complex, but one-time repair costs for it, most likely, will be unjustified.
Details and consumables should be purchased as needed. It makes no sense to store all spare body elements in the garage. In addition, their acquisition should not have problems for most car models, with the exception of particularly rare, as there are many such goods as branded and non-original. Features of the organization of the workplace can be explored on video.
Types of body repair
Small or local repairs. For these works, complex equipment is not required, and the technology of their execution is very simple. For small repair, the tools from the standard set, as well as the welding machine and the paintopult, are mainly used. However, it is relevant only in the event of the intake of the subframe and structural elements of the body.
Exterior repair
It implies cosmetic works like painting and airbrushing. Therefore, requires tools for working with paint and varnish materials.
Overhaul
This category refers to the replacement of parts and plating, welding, restoration of geometry. In this way, it is usually eliminated by the consequences of large traffic accidents or recover old cars. In the first case, it is advisable to perform repairs only under the condition that the total cost of work will less price new detail. And in the second one you need to pre-assess the resource of the machine, that is, how long will it be possible to operate the car after repair. It is desirable to attract specialists to this.
Separate types of work
To make any body repair on your own, it is necessary to perform a number of works that make up it. The main types of body works are further considered.
Scratching scratches and chip
This is one of the most simple body operations that does not require special skills and the use of complex equipment, so it is forces to fulfill many. Pre-damaged body portion is cleaned and degrease. The technology of work consists in applying putty and its grinding with abrasive material. It should not save on consumablesSince their properties determine the quality of the result.
Painting
In the case of repairing any part of the body, you should choose a column of paint corresponding to the source. To find out, you need to look at the plate located under the hood or on the left rack, if the car was not repainted.
Before starting work, it is necessary to cover all the parts adjacent to the working surface that are not subject to painting.
In order to avoid falling on her extraneous particles, painting needs to be carried out in a clean room, and antistatic napkins should be used to remove them. If the performer is not familiar with painting technology, it is necessary to first examine it on video and work out.
Leveling geometry
For these work, it is necessary for the presence of a stable or a specialized stand. The technology consists in applying multidirectional efforts to a damaged surface. Thus, the damage obtained as a result of lateral shocks is usually eliminated.
Installation of patches
This technology is used to replace damaged corrosion of body fragments. Patchworks are fixed by welding for which it is most often used.
Removing dents without painting
A very simple technology that allows you to correct the defects of small and medium size, provided that the paintwork is not damaged. There are several ways, for example: tapping, pulling, thermal and other.
Other
- Anticorrosion treatment implies stripping of affected rust surfaces and subsequent treatment with specialized compositions.
- Polishing consists in applying polyrolol and rubbing. Polish both damaged cars for masking repair points and new to protect paint coating And give an attractive appearance.
Visually see the technology of execution of the described works can be in the video. And although some of them are so simple that this does not need this, the video about the editing of the car will help in the implementation of more complex types of body repair.
Article on the main types of car bodywork - tools, work order, tips and recommendations. At the end of the article - video about the important secret of body repair.
The content of the article:
Timely repair of the body and painting of the car significantly increase the service life of the vehicle. The car owner must periodically produce not only the external inspection of the car, but also to look into more hard-to-reach places - under the bottom and hood, since the body is important and expensive element cars.
The rapid detection of the problem affects both the speed of its implementation and to the substantial savings of money. The slightest scratch or harmless bulb make metal defenseless metal before corrosion, which is capable of disrupting the integrity of the surface during the year.
Varieties and causes of car damage
Fault categories:
- mechanical;
- corrosion;
- the destruction of the anti-corrosion surface.
As a result of the car accident, there is a violation of the geometric parameters of the car, the return of which is carried out to the original factory state, service centers and auto repair shops. Moreover, damaged elements can be replaced if they cannot be restored.
Classification of car bodywork
The restoration of the body elements of the car is divided into two main categories: local (small) and complex (capital).
Also isolated subcategories. For example, external repair and operation of medium complexity. The first implies the application of paints and varnishes (LCP) and airbrushing, and in the second case, carrying out restoration work with the possibility of replacing individual parts.
The reconstruction of the body can not always be performed with their own hands, since with extensive damage, diagnostics and specialized tools are required.
Types of body repair:
- Restoration of geometry. Return of the geometric parameters of the body to the factory. If necessary, it is replaced by parts using cutting and welding metal.
- Paintwork. Painting body is made after its repair and processing.
- Selective (local) painting. There are damaged or replaced parts. At the same time, careful attention is paid to the shades of paint, in order not to have a color imbalance.
- Abrasive polishing. It is used if the LCA has damage in the form of shallow scratches and non-critical defects. Abrasive pastes are used for various grainability. Read the article - do it yourself.
- Local anti-corrosion work. The affected parts are cleaned to the surface of the metal. For these purposes, rust converters are used.
- Restoration of the front and rear bumper.
- Restoration of thresholds. Works imply restoring places for the jack.
- Tin work.
- Welding work.
- Work on the Shelon. A device designed to restore the body shape after accidents.
- Richtovka.
Uncritical damage to the surface of the body of the TC in order to save time and means can be eliminated with their own hands. First of all, this is due to the prevention of corrosion manifestations.
Before starting work, you should be used by the necessary materials:
- primer and paint;
- emery paper;
- solvent;
- splitel.
After drying the primer, paint is applied - by spraying or with a brush. If a faithful shade is selected, the restored area will not stand out on the surface of the body.
If corrosion traces appeared, elaborate paper or sandblasting will be required. The stripping of the affected area should be carried out with the "capture" of the LCP. The nude metal is processed by a solvent, and a spatlet is used to align the working surface.
Puttailing (if necessary) is carried out in several layers. At the same time, each layer is grinning and degreased. The finish stage is to apply primer and staining the surface.
Repair of the bottom of the car
Most lives of cars producers are treated with special mastic capable of fighting corrosion over the years. The effectiveness of the mastic is reduced to zero in disruption of the integrity of the protective layer.
Riding on roads is not better quality (seeker, forest, with potholes on asphalt coatings, etc.) leads to damage to the bottoms of the vehicle. In this case, it is necessary to protect the scratched metal in a timely manner, since additional (unwanted) sources of ventilation will appear on the influence of corrosion in the floor of the car.
The restoration of the protective bed of the bottom of the car is quite possible to make it yourself. This is a simple process, but uncomfortable. Be sure to have the means to protect the eyes - mask or glasses.
Materials for repair work are:
- sandpaper;
- solvent;
- primer;
- bituminous mastic.
When the dent has an open character (chips, detachal), then with the right approach you can do without the help of professionals.
First, it is necessary to align the damaged surface. With the help of a suitable tool (dummy, mount, handle hammer) with inner Body parts apply dosed power. Rubber tips are used to avoid scratches.
Stripping, putty, primer and coloring are performed after the working surface is maximally aligned.
The car frame is primarily a metal that is able to serve not more than a dozen years, but it is defenseless before corrosion. Inside the car sufficiently hard-to-reach places, but the most vulnerable are the following:
- niche doors and trunk lids;
- thresholds;
- spars.
Anticorrosive processing is made without a body parts pars. To accurately perform it, you need to refer to the guide for the car, in which there is usually a scheme for conducting anticorrosive works of hidden cavities and ways to access them.
Overhaul
When the body structure has critical damage or required full replacement details, produced overhaul. Such procedures are required after car accident or natural disasters.
At the same time, the independent alignment of the geometry of the body and further repairs are impossible without specialized tools and suitable conditions. It is in such cases that the access to specialists is relevant.
Equipment required for the reconstruction of the body in service centers:
- lift;
- stipel (used in the restoration of the geometric parameters of the automotive body using electronic high-tech measuring systems);
- welding machine;
- jack;
- sPOTTER (for the execution of richtovka);
- pneumatic tool;
- locksmith tool;
- inventory for hard work.
This method of removing irregularities on the surface of body elements has now gained high popularity. Such methods in the soul of any car owner, since during the operation of the vehicle, the emergence of "hurt" defects on the surface of the body parts. Such damage may occur as a result of the intentional or unsighted effects of hands and feet, due to hail, unsuccessful parking and other factors.
Consumer Alignment Significantly saves the time of motorists. Financial savings are also evident, as it disappears the need to buy various "cosmetic" means.
The main advantage of such a restoration is the high quality of the work performed.
Soviet car industry for such a repair is not suitable due to the soft body cover. With your own hands, this restoration is better not to produce, since without the proper skill and the presence of the necessary tools to get rid of dents without a disorder of the LCP is almost impossible.
For convenience, the bumper is usually removed and the composition of the element is determined.
Proceedings:
- irregularities are removed by heating;
- scratches with chips put off and grind;
- when faults are used by heat seater;
- the product is painted with standard methods.
Polishing happens two types - protective and abrasive. The first is to apply to the surface of the extravagant components on the surface of the body, and the second is in applying abrasive pastes on the LCP, pre-purified from the thin layer of factory paint.
In both cases, polishing serves to eliminate small scratches On body elements and gives the appearance of the machine to the factory state.
Ricking works are to adjust damaged bodies. These include both the restoration of the geometry of the car and the correction of dents and damage. The ultimate goal of Richtovka is to bring the body parts to the state in which they were after stamping.
When carrying out a straight repair, an anvil appropriate configuration is used. By virtue of changes in the physical properties of the metal when working with it, it is necessary to have not only special hammers, but also the right "shock alignment" - blows weak, but frequent. If the work surface of the product has folds, the recovery begins with them, with a movement to the center of the defect. At the same time, it is necessary to check on the touch restored metal after several blows in a row.
Conclusion
Body repair TS can be performed with your own hands if:
- damage not critical level;
- there are necessary inventories and recovery tools;
- the owner has due skills.
Corrosion is the main enemy of the car and its owner. Rust is able to destroy the car of any manufacturer. The first anti-corrosion processing must be carried out in service centers. And B. russian conditions This is necessarily even in cases where the car only comes out from the factory conveyor.
With a proper approach and attentive terms, the car is able to serve its owner not one ten years.

External damage to the machine - an event, unfortunately, frequent, and the cost of holding even a small body repair in terms of car service is quite high. But some damage to the housing is quite easy to eliminate themselves.
To the honor of Russian motorists, many of them, unlike their ingenic colleagues, have good skills to carry out body repair with their own hands. True, this dignity is based on the negative aspects of our reality. The state of roads, to put it mildly, is very far from the ideal, and the level of salaries has not yet reached that value when about any dent can be afforded to contact the car service.
Not any car is insured against "injuries". Even with impeccable observance of the rules for its owner, the probability of an accident remains - unfortunately, not all drivers are supporters of the established order of driving on the roads. In addition, damage (scratches, dents, chips) can be obtained by just leaving the car in the parking lot.
There are another terrible enemy in the cars - a time that does not gentle the steel bodies. Considering the attachment of most of our car owners to their machines, eliminating corrosion consequences becomes one of the main tasks of body repair.
It is necessary to immediately make a reservation that an independent body repair, if you do not have professional skills and specialized equipment, it is possible only with small damage that do not affect the carrier elements of the car's design.
The fight against corrosion is one of the most time-consuming processes, but if they neglected, it is enough short term The car, not even, will lose its external appeal. Well, if the time is already missed, and Rust makes itself felt by red spots, it is necessary to urgently take measures to localize and eliminate corrosion foci.
Purification of the body from rust implies two stages of its conduct - mechanical stripping and processing special chemicals. For the first stage of work will be needed
- metal brushes (manual or in the form of nozzles on a drill or "Bulgarian"),
- good reserve of sandpaper with grain 60-80,
- soft rag.
To carry out chemical removal of rust, you must purchase an appropriate reagent. The range of rust transducers is quite large, mainly, they are made on the basis of orthophosphoric acid. Available in both the liquid variant and in gel or aerosol. Of course, all modifiers have their own specifics, so they require compulsory attentive familiarization with the rules of their application and compliance with the recommended security measures.
- First of all, you need to thoroughly wash the car and reveal the corrosion foci on its surface.
- Mechanically (brushed or sandpaper) Rust spots are cleaned to "healthy" metal. Apply the anti-corrosion remedy immediately - it is difficult to foresee the depth of the defeat.
- No matter how old, small foci of rust will remain in pores or cavities, where it is already impossible to penetrate the mechanical path. At this stage, the rust converter is started (in accordance with the instructions for its use), which should not only completely dissolve it, but also to cover the affected area with a kind of ground coating suitable for further putty. General Tips Here it is impossible to give - some formulations require a mandatory wash after a certain reaction time, others, on the contrary, remain at the place of application until complete drying.
- It often happens that corrosion eats metal to a thin "mesh" or at all through. It is possible, of course, through holes to smoke fiberglass using epoxy compositions, but still optimal decision There will be a loading of a plot and a soldering of a metal patch. The suspended area will not be subject to further corrosion, and the stamped latch is easy to break inward, to put the necessary thin layer of putty on top.
- We must not be forgotten about the purified areas must be immediately processed by the anti-corrosion composition. At intermediate stages of work, it is necessary to exclude even the slightest probability of entering the surface of the water.
Scratching
Scratches on the machine body - general headache. The reasons for their appearance are mass, even if you do not count the accidents: flying from under wheels Stones and foreign objects, uncircumbed branches of shrubs and trees, playful children's hands or anyone evil intent. How do you perform body repair with your own hands if it comes to such damage?
If there is no deformation of the housing, first of all, it is necessary to accurately set the depth of the scratched layer - it may be easy damage to the upper varnishing coating, the integrity of the paint layer or a deep groove to the metal, with the exfoliation of the paint coating. As a rule, with good lighting it is visible to the naked eye, if you wish, you can use the magnifying glass.
With superficial damage, when a layer of protective varnish is scratched, you can apply special poly rays (liquid or pasty) or polishing pencils to remove light scratches, for example, recommended by many Fix IT Pro or SCRATCH Free Auto owners. The principle of their application is simple:
- The surface is thoroughly washed away from dirt and dust using detergent and wipe dry.
- The damaged area is applied polyrolol and dry clean x / b rack circular movements rubbed into the surface.
- After complete drying of the composition (according to the instructions applied to the medium), the final polishing is performed.
If the scratch is deeper, care will be much larger. Restoration pencil will be required (for example, NEW SN) or a small amount of paint - a difficult moment in both cases is proper selection necessary shade.
- The surface is thoroughly washed with the auto-mapping, wipe dry, degreases. In order to avoid getting paints on the intact section, the area around the scratch is better to protect with painting scotch.
- With the help of the pencil, the painting composition is applied. If there is no, the scratch is neatly filled with paint using ordinary toothpick, but not to the surface itself, and so that the place is left to apply the polishing composition.
- After complete drying, the paint is made as described above.
Highly good feedback Deserted a method of embedding scratches using the 3M Scratch and Swirl Remover tool, which does not require the selection of the necessary paint. In fact, this composition slightly dissolves the LCP surrounding scratch, and fills it. After polishing, damage becomes almost imperceptible.
If the surface of the surface is up to the metal led to the destruction (rocking, cracking) of the paint coating, then there is no simple restoration methods. We will have to get a scratch, apply an anti-corrosion composition, put a damaged area, align it and prepare to paint. Often it causes the need to paint a whole body element.
Demoting, Richtovka
This process is one of the most difficult, and you need to make a good way to evaluate your capabilities before you take for this work.
First of all, a specialized tool is needed, which is far from all. Secondly, work requires high skills - the master must "feel" metal. Thirdly, it is not necessary to rely too much on the body repairs placed in the network with your own hands - what seems simple and understandable on the screen, can go not quite so in practice. Nevertheless, if the desire to experience your strength prevails, you can try several ways.
If the dent has not formed a metal fence ("Flone"), you can try to squeeze it smoothly from the inside. For this, levers or hooks are used if there is a point of stop for the application of force from the inside of the housing. Sometimes, for straightening dents, a sufficiently small effort or several light blows of the xyiyan (rubber hammer).
Some craftsmen use car chambers for pressed "Floating" (cameras from balls). The method is old, but often very effective. The chamber is placed under a dent, it is launched to avoid breaking with cardboard or plywood pads or placed in a tarp case. When pumping it with air, it can, increasing in the amount, straighten the metal into place.
It is recommended to try the heating of dents around the circumference with a construction dryer, and then sharp cooling with liquefied carbon dioxide (for the extreme case, just with wet rags). Sometimes it gives a very good effect.
If you managed to get at your disposal a vacuum sucker or spotter, then the problem can be solved even easier. The application of force with the outer side of the dent allows you to maximize the body geometry, even without damaging the paint layer. However, this method is applicable only to cars that have not previously underwent shtclosure and repainting. An example of using Spotter is demonstrated in the proposed video.
If the dent is large, deep and conjugate with the obvious metal chance, you will have to do Richtovka.
- Start it also with the maximum exhaust to be repaired part. If some elements of hardness (racks or ribs) are injured - you need to start with them.
- Reference of the site with the chances start from the edges, gradually moving to the center. After squeezing large dents, it is possible to move to the rough recovery of the geometry of the part, using straight hammers and anvil. Perhaps it will take point heating around the straightening area - this can be done with the help of a construction dryer.
- The quality of the richtovka is inspected constantly during the work. Bougraov and deep holes are not allowed, which will not give a qualitatively to make shtclosure of a damaged area. After completion of the work, the refined area is necessarily completely purified from the paint coating to the metal.
Basic rules and possible difficulties.
Putty and preparation for painting
Final form damaged details The body is attached to the putty. Before starting work, the surface is thoroughly washed, dried, cleaned from dust. Special attention should be paid to the transitions to the intact section - the putty will not fall on the glossy coating, it must be cleaned with a shallow skin to frosiness. Immediately before applying the spacion layer, the surface is degreased by a solvent.
Body - the main element of the car, providing it good job. This component has a complex design, and periodically exposed to high loads. There are problems that require interventions arise. Body repair allows you to restore damage and return the working condition of the car.
The reasons are repaired two factors:
- technical;
- human.
The most common manifestation of the first factor is wear. Most body damage is obtained as a result of a natural process. This component has an operating period, after which the strength indicators are reduced, and it becomes vulnerable. The most common cause of wear is corrosion.
Sometimes the cause of problems with the body becomes non-compliance with the rules of car storage, or incorrect use. These actions refer to the human factor. Also in this category includes:
- constructive flaws made by the manufacturer;
- defect faults arising from the machine assembly;
- damage as a result of low-quality repair.
The human factor includes an accident. More than 50% of accidents are accompanied by damage to the body's body part.
Common body faults:
- operational;
- constructive;
- technological.
Damage to the body includes disorders of the initial state of the element, from minor scratches to large dents or chances.
Organization technological process Work on the restoration of the car begins with diagnostics.
Diagnostics determines the presence of all faults, their features and character. Thanks to this, it is easier to choose a body repair method. Diagnostics are performed in three stages:
- There is a paint coating machine for the presence of defects.
- An assessment of the body geometry is given - if irregularities have enough inspection without special equipment.
- The quality examination is carried out, which allows you to determine what state is the welds and fasteners. This task requires attention and experience, since the main load is distributed to these elements.
After detection of faults, the plan of repair work is drawn up.
What is body repair
Body repair is a complex of technological actions aimed at restoring the body. The basis of this process involves the elimination of damage to any nature.
Two types of body repair are distinguished:
- full - applied while eliminating the damage to a large size. Most often it is used when recovering a passenger car after the crash;
- local - used when detecting scratches, chips and other minor damage.
The car repair technology is depends on the fault level. With a high level using full recovery requires special equipment.
Exterior repair
Can be implemented at home. Repair of local type does not require labor-intensive actions, and is used in eliminating minor damage. The body repair includes restoration:
- scratches and chips;
- small dents;
- an early stage of rust metal.
External repair of the body is performed using:
- standard set of tools for body repair;
- polyrolol;
- paints.
Eliminate overall damage to the elements of external repair can not. Additionally, you may need tools for airbrushing and processing fiberglass.
Overhaul
Body restoration in most cases cannot be performed independently. It requires its implementation. professional equipment and special skills. This type of restoration work involves the analysis of the car. His goal is to detect all defects and small damage. Performing restoration, even minor elements are removed.
To detect hidden defects, drill contact welding zones.
Welding works are carried out when:
- corrosion details;
- cracks in body design;
- deep deformation of details.
Overhaul does not work out without replacing damaged structural elements.
Leveling geometry
The main tool used to restore the car body is a stapel. This tool is designed with high strength indicators sufficient for power works. The main action during alignment is a hauling. It involves the use of the fasteners system acting on the design points at a pressure of which body detail Acquires the original form. This task implies a high level of difficulty, to cope with which in the absence of experience is not easy.
Using a stripping installation, measurements are required to accurately carry out repair work. The alignment of geometry is carried out in stages:
- Fix the vehicle on a stripping platform.
- After calculating points on the machine, the equipment is attached to them.
- Run a stripping installation.
After starting, the stapel and the equipment automatically pull damage to the desired form. Equipment involves the use of a computing program, calculating the required level of effort and the rack measurement indicator.
The advantage of the stripping installation is that it does not disrupt the quality of the metal in fault areas when eliminating them.
Elimination of dents
Body repair of the car dents are carried out in three ways:
- With the help of glue. Richtovka or editing is performed using the POPS-A-DENT set. It includes thermopystole, silicone glue, special rods. After applying glue and attaching rods, it is necessary to wait for frozen. Then carefully pull the dents along with the rods.
- Using vacuum. The main special tool is the vacuum suction cup. It is attached to the surface of dents, creating a vacuum. After that, a dent can be pulled out without the risk of damage to the surface of the coating. The use of vacuum suckers is arugious way to eliminate dents.
- According to PDR technology. With the help of special levers that are entered through the car's technological holes can be reached large dents and eliminate them with extrusion.
Installation of patches and welding
If the standard Local Body Repair does not help, patchwork is used. They are used to close holes in the car body. The patch allows you to repair and end-to-end rust if the hole diameter does not exceed 8-10 centimeters. Otherwise, the item is completely replaced.
Before mounting the patchwork, the edges of the opening are processed. The patch itself must have a diameter greater than the size of the damage (the flashes is welded). For its manufacture, a thin metal is used. For fastening, a solid seam is used. It is recommended to use semi-automatic type welding machines.
Elimination of scratches and chips
Scratches and chips are cleaned with small body repair. It involves the use of painting and polyteroli. Additionally, you can apply primer. Surface is grouped, then applied protective covering. New technologies provide grinding, after which fails will not be visible. Cosmetic type of repair is easily performed at home.
Paint must have body covering color. Otherwise, the surface of the car will look unprepacently.
Painting and polishing
For painting in accordance with the technology of car repair, it is necessary to use only substances designed to cover the surface of the car. In some cases, several stages are required. After repairing the body and painting the surface surface is thoroughly washed.
The painted machine is polished. Grinding is performed using soft-type abrasives only after complete paint drying.
Even minor accidents can turn out quite large financial costs. When contacting workshops, a high price can be exhibited. Eliminate body deformation, remove cracks and destruction, restore the paintwork and make a polishing of the car headlights with their own hands. For this you need to have required tools, resources and some time in stock.
Types of repair of body
At home, recovery is carried out with a few methods:
- Complicated.
- Local (small).
- Painting and polishing.
Body repair with your own hands requires careful preliminary preparation. It is recommended to study the sequence of actions and watch the video "How to make body repair yourself".
Sophisticated repair
Complex body repair Auto, made with your own hands, provides for richtovka different dents. If necessary, the damaged elements are replaced, for example, wings, geometry restoration and semi-automatic welding.
Minor repairs
Small repair of body car used for correction small dents, chips and scratches. Otherwise, they may entail the appearance of corrosion foci (rust). The small repair of the car is carried out with your own hands only after the end of the warranty period.
Body work include:
- Recovery of geometry is carried out after dismantling all removable items.
- Elimination of dents and traces of corrosion, sacking of holes and delete all defects. If there are hopeless elements, they are replaced.
Polishing and painting
Body repair and painting - Stages requiring special attention. It is not worth cleaning the surface that exceeds damaged areas in size. The final stage of body repair and painting with their own hands is paint with a compressor.
For polishing on their own, after drying paint, it is recommended to use grinders.
Phase diagnostic stages
Car repair requires a preliminary estimate carried out in several stages:
- Determine Body VIN-code.
- Compare with a sample represented by the manufacturer.
- Step by step check the body parameters in places that are problematic.
From Wikipedia: Vin. (Vehicle Identification Number) - I. dental vehicle numberConsisting of 17 characters, information about the manufacturer and characteristics of the vehicle is encodered, and the year of release.
If the repair of tin cars performed by their own hands requires scanning of the thickness of the paintwork, then it uses brass, aluminum and ferromagnetic materials.
Types of body damage
In order to make body repair, you should define type of damage:
- Deformation of individual areas.
- The appearance of cracks and destruction.
- Distortion of the shape of the openings (window, door).
- Violation of anti-corrosion and paintwork.
It is impossible to prevent the emergence of operational damage. In order not to spend a lot of money to eliminate them, you can repair the body yourself at home.
Methods for restoring tin car
- If metal strongly damaged, then for the repair of the body you need to:
- Use anvil And small cyanka.
- Attach an anvil to the outside of dents.
- Make from the inside of the unlock blows by the image.
From Wikipedia: Kiyanka - Joinery hammer from solid wood or rubber
Definition of geometry
With strong deformations of body repair of the car requires full removal of LCP. IN this case For a complete restoration of the body can not do without a welding machine and an industrial hair dryer. Welding is carried out using graphite electrodes. At first, the dent straightened from the rim to the central part. For this, the metal heats up and only after that resort to point exposure. Thanks to this, the tin becomes militant and plastic.
Straightening dents without painting
The restoration of the body of the car during nonset deformations can be carried out without repainting. In this case, the change in the shape is carried out mechanically. The process takes a lot of time and implies the impact from the back side.
Metal attack on dent
When repairing a body repair without pulling attachment method Special solder using soldering iron, acid and flux (chemically active substance). This option allows you to eliminate defects and get the perfect result.
Method of point welding
Car repair during body damage provides a fix defect outside the whole. Using a welding electrode Picks up the metal on the deformed area. Pull out is carried out by reverse hammer. The graphite electrode is rooted and grinding the welding place.
Patch welding on the body
Independently you can eliminate even through holes. In this case, you need to fully cut a damaged piece, then welcome the patch. If the corrosion areas are not large, it takes a cleaning of damaged areas to whole metal.
Sequence of bodywork
When repairing the body, as shown in the video, you need to follow the sequence of actions:
- Restoration of geometry.
- Holding welding work And Richtovka.
After completing the body repair, paint and polishing are carried out:
- Cleaning, dismantling outdoor parts (bumpers, headlights and lighting).
- Processing of defective seats To pure metal by the chisel and sandpaper.
- Applying putty On an uneven surface.
- Next goes stage grinding and primer.
Required tools and materials
Before making auto repair with your own hands, you should get everything necessary:
- Hammer, keys and measuring devices.
- Homemade stapel with a purchased hydraulic unit.
- Schlifmashinka and sandpaper (№60 or №100).
