1. Rim scratches and damage: This kind of damage is very common. When the rim of the vehicle is close to the edge of the main road, it is very easy to rub against the rim of the hub when rotating. This situation can be repaired and renovated according to professional welding technology.
2. Rim cracking and damage: When the rim of a vehicle is hit by a hard object, the rim of the rim will crack. In this case, the steel ring can be repaired according to a special aluminum welder. Then after electric welding, the steel ring is repaired, reshaped and beautified.
3. Blank rim: When the rim collides with rocks or hard objects, the rim of the vehicle rim will bump out of the gap, and special rim compensation ash must be used for compensation.
4. Deformed rims: When rims collide, this is a serious situation. If the internal structure of the hub is not damaged, it can be corrected by plastic repair and special straightening machine. But if the deformation is too obvious, the steel ring should be removed and replaced immediately.
Car rims are also called wheels. According to the material classification, it can be divided into steel wheels and aluminum alloy wheels. These two different wheels have their own advantages and disadvantages. The manufacturing process of steel wheel hub is simple, the cost is relatively low, and the brittle fracture resistance is strong, but there are some defects such as large net weight, large inertia friction resistance, poor heat dissipation and easy corrosion. Aluminum alloy wheels just fill the problem of steel wheels, but the price is more expensive.
