How long does it take to learn automotive sheet metal?

It takes about 3-6 months to learn painting in automotive sheet metal, and the basic operation should pass. Automotive sheet metal is eager to learn painting, because there are not many requirements. As long as you are interested, you can learn. It is not difficult to learn automobile maintenance technology, but if you want to learn it well, you must spend a lot of time practicing and accumulate more experience. Practice makes perfect to get started. Sheet metal and painting are two types of work, sheet metal workers and painting workers. When painting in automotive sheet metal, it should be handled by the sheet metal worker first, and then painted by the painter. Sheet metal workers need to learn how to use basic equipment, such as grinding, disassembling and drawing. Painters need to learn the covering, putty, spraying and drying of various paints.

The basic process of sheet metal painting is usually divided into five steps:

1. Confirm the scheme: according to the severity of vehicle collision, formulate the corresponding maintenance scheme. If it is a serious traffic accident, it will also involve engines, gearboxes and circuits. At this time, it is necessary for the personnel of the machine maintenance department to disassemble and repair.

2, sheet metal correction Sheet metal correction needs to repair the deformed parts through corresponding maintenance equipment according to the deformation degree of the car body. Sheet metal includes cutting, grinding, stretching, tempering and deoxidation. The purpose is to restore the deformed parts to the original state and maintain the original rigidity of the metal.

3. Scraping and shaping: After the vehicle passes through the sheet metal, there will be many defects and repair marks, which cannot be remedied by the sheet metal work. Even if new parts are directly replaced, there will be imperfections. At this time, it is necessary to reshape the waistline and flatness of the body by scraping and shaping. This program seems simple, but it is actually a test of workers' skills.

4. Painting: The painting process is also complicated, and the requirements for the working environment are also high, so it needs to be carried out under dust-free conditions. Painting is mainly divided into the following steps: spraying the first primer-spraying the intermediate primer-polishing the intermediate primer-mixing the paint-spraying the topcoat-drying the paint surface.

5. Paint surface treatment: Paint surface treatment is the last process in the whole work of sheet metal painting. In fact, no matter how careful workers work, they will leave some imperfections more or less. Even some dust floating in the air will affect the overall effect. At this time, we can only rely on this link to remedy. Usually, the main remedy is to polish it with superfine beauty sandpaper or polishing machine to achieve the "mirror" effect.
