In the process of using the car, it is inevitable to encounter various accidents such as collisions and scratches. At this time, automobile sheet metal repair plays a vital role. It can restore the damaged car body to its original shape and appearance, which is not only related to the beauty of the vehicle, but also closely related to driving safety.
Definition of Auto Sheet Metal Repair
It is the process of repairing and restoring metal parts of the car body that have been deformed or damaged due to collision, extrusion, etc. The car body is mainly made of stamped and welded metal sheets. When the vehicle is impacted by external forces, these metal sheets will dent, wrinkle, break, etc. Sheet metal repair work is to restore the deformed metal sheets to their original state through a series of professional tools and techniques to ensure the integrity of the car body structure and the smoothness of the appearance.
Advantages and features of automobile sheet metal repair
Restore the integrity of the body structure
The body structure of a car after a collision may be severely damaged, affecting the safety of the vehicle. Sheet metal repair can ensure the stability and safety of the vehicle in subsequent use and reduce the safety hazards caused by damage to the body structure.
Maintain the appearance of the vehicle
Scratches, dents and other damages to the body will greatly affect the appearance of the car. With superb skills, sheet metal repair masters can fill the dents and flatten the wrinkles on the surface of the body, and then cooperate with subsequent processes such as painting to enhance the overall value of the vehicle.
Cost saving
In many cases, sheet metal repair can retain the original body parts, and only the labor cost of repair and a small amount of material cost are required to restore the damaged parts to normal use.
Environmental protection and energy saving
Reducing the replacement of body parts means reducing the production of new materials and the disposal of old parts.

Damage assessment
The maintenance personnel will first conduct a comprehensive and detailed inspection of the damaged vehicle, and evaluate the location, degree and scope of the damage to the body through visual observation, touch and professional measuring tools. Determine which parts have deformed, the depth of the dent, whether there is a break, etc., to provide a basis for the subsequent formulation of a repair plan.
Formulate a repair plan
Based on the results of the damage assessment, the maintenance personnel will formulate a personalized repair plan. For minor dents, traceless repair technology may be used; for more serious deformations, sheet metal tools need to be used for stretching, knocking and other operations.
Sheet metal repair operation
Dent repair: For dents that do not involve paint damage, traceless repair technology is often used.
Wrinkle repair: When wrinkles appear on the body, the wrinkle part is usually stretched with a stretching device to unfold the wrinkles.
Welding repair: If the body parts are broken, welding repair is required.
Surface treatment: After the sheet metal repair is completed, some repair marks may be left on the body surface, such as welding points and grinding marks. At this time, surface treatment is required, including puttying, polishing and painting.
Application scenarios of automobile sheet metal repair
Repair after traffic accidents
This is the most common application scenario of automobile sheet metal repair. Whether it is a minor rear-end collision, scratch, or a more serious collision accident, the body of the vehicle will be damaged to varying degrees. Through sheet metal repair, the accident vehicle can be restored to its pre-accident state and put back into normal use.
Daily scratch repair
During daily driving, the vehicle may scratch other objects for various reasons, such as accidentally rubbing against roadside obstacles when parking, and minor scratches with other vehicles.
Used car refurbishment
For used car dealers, in order to increase the sales price and attractiveness of used cars, they often perform sheet metal repair and preparation on the acquired used cars.
Car modification
During the process of car modification, sometimes it is necessary to make some structural adjustments or changes in the shape of the car body, such as cutting, welding, stretching and other operations.
As an important technology in the field of automobile maintenance, automobile sheet metal repair plays an irreplaceable role in ensuring vehicle safety, improving vehicle appearance and saving maintenance costs.
