Fast Technology March 25 news, recently Great Wall Motor held the second-generation Hi4 technology and the new Haval Xio Long Max pre-sale launch event, a blogger at the venue met with Great Wall Motor Chairman Wei Jianjun and asked a very sharp question.

It indicates:Mr. Wei, how do you view the issue of some domestic cars rusting? Many people are hesitant to buy domestic cars because of this reason.

After hearing the question, Wei Jianjun, after a brief moment of thought, responded that everyone should still look at the longer term.I think rust is not a process issue, it might be a design issue, and there is also a matter of conscience.。

After saying this, Wei Jianjun turned and walked towards the venue, and his response was met with enthusiastic applause.

The car uses a large amount of metal parts, especially the chassis, which, over long periods of use,Some cars do indeed rust, especially in coastal cities., many people who bought domestic cars in the early years have experienced this.

The reason for rusting is multifaceted:

for example material selection, some automakers, due to cost and brand positioning constraints, use ordinary steel plates instead of high-quality rust-proof materials such as hot-dip galvanized steel plates, all-aluminum, or composite materials. These ordinary steel plates have poor rust resistance and are prone to rust.

production process, inadequate processes in production such as electrophoresis, painting, and welding, for example, insufficient electrophoresis or defective welding, can result in weak points in the vehicle's protective layer, making it easy for moisture and oxygen to intrude and cause corrosion.

Also, the design issues mentioned by Wei JianjunIf there are unreasonable structures such as sheet metal sharp corners and dead corners, it will make it difficult for anti-rust treatments like electrophoresis and wax injection to fully cover, forming weak areas in rust prevention.

in addition, there are assembly defects, during the assembly process, if different metal parts are improperly connected, forming a galvanic corrosion, it will accelerate the rusting of the metal.

Of course, in addition to design, production, and manufacturing itself, rusting is also closely related to the user's usage habits. Some people are careless.Driving in a more unrestrained manner, daring to take any road, being lazy about handling bumps and scrapes, along with long-term neglect of car washing, accumulation of acidic stains, etc., can all lead to rust.。
