During daily use of the car, the frequency of wheel scratches and damage is still very high. When the wheel is slightly damaged, the cost of replacing a new wheel is too high. The wheel repair has obvious effects and reasonable prices, and it seems to be a good choice.
The role of the wheel is not only for beauty, but also for the protection of life safety. Although, wheel repair is very cost-effective. But is wheel repair definitely reliable? Will it affect safety? With these questions, we will combine the actual repair process today to see whether wheel repair is reliable.
What are the types of wheel damage:
Usually, the damage of aluminum alloy wheels is basically caused by external forces, which can be roughly divided into three types.
1. Surface damage, mainly wear and abrasion of the wheel surface.
2. Deformation damage, as the name suggests, is the deformation and distortion of the wheel edge under the action of external force.
3. Fracture damage, when the wheel is hit hard, the wheel b breaks to varying degrees.
How to repair these three types of damage? Is each repair method reasonable?
The first one is surface damage repair
Common wheel damage is mainly scratches and abrasions on the wheel. The repair only processes the surface, which basically does not affect the main force-bearing structure of the original wheel, and has little impact on the reliability and safety of the wheel. The repair process is relatively simple and the process is relatively mature.
The repair steps are as follows:
The first step is sandblasting and grinding: First, the wheel should be rough-grinded before repair. The stubborn dirt on the wheel should be cleaned by sandblasting, and the adhesion of the wheel surface before painting should be enhanced. This step can be solved with a sandblasting machine.
The second step is aluminum welding filling: If the gap on the edge of the wheel is obvious and cannot be filled with putty, the gap can only be filled with aluminum welding.
The third step is CNC wire drawing: After the programming work is completed, the lathe cuts the surface one by one according to the settings until all the scratches disappear. This will use the currently popular wheel repair machine, such as alloy wheel repair machine).
Second, edge deformation repair.
Generally speaking, if the wheel can be deformed, it is mostly due to the strong external force impact caused by careless driving. Nevertheless, the merchant has a way to repair the deformed wheel.
The first step is to detect the deformation position. First, find the position of the wheel deformation, install the wheel on the wheel straightening machine rim straighten machine, find the deformation position for calibration.
The second step is heating: use a blowtorch to locally heat the deformed position, and stop heating after reaching a certain temperature.
The third step is correction: the wheel becomes soft after heating, and the hydraulic arm is used to make repeated slight corrections.
The third type: wheel fracture.
Some advertisements or articles introduce that the wheel fracture can be repaired by welding. Although the broken part can be welded together, the wheel is no longer reliable at this time. The wheel fracture is the most serious damage to the wheel. It is recommended not to repair it in this case.
In summary, wheel repair is not omnipotent. The surface repair of the wheel and the deformation of the edge part can be repaired well, but the wheel fracture should not be repaired as much as possible to avoid danger.
