Repair technology of aluminum alloy profile hub
1. Check the damaged parts and types of the hub. Generally, there are scratches, embrittlement and blackening on the wheel hub surface, wheel hub rim deformation, wheel hub cracking and fragmentation.
2. Make clear the appropriate repair process and polish the wheel hub.
3. If the hub is deformed or cracked, it needs to be repaired by shaping and welding first. If there is deformation and gap, first carry out shaping and electric welding, and then use measuring instrument to check the repaired parts to ensure that everything is normal on the wheel hub.
4. After shaping and welding, the wheel hub needs to be polished at the welding place to check whether the whole wheel hub is irregular or the topcoat treatment is irregular.
5. For tiny scratches, you can choose special aluminum alloy profiles for the hub to repair, while cracks and gaps need to be repaired by aluminum welding process, and after repair, they need to be polished, and at the same time, the uniformity of the hub surface should be checked.
6. In order to improve the adhesion of the paint on the wheel hub surface, the aluminum alloy profile wheel hub is oiled. After spraying the top coat, send it to a high-temperature oven for baking. It will be taken down to dry in the back, and then gently polished after the paint has dried to the bottom.
7. Inspect the repaired hub, and check the safety factor of the hub according to the in-loop inspection and rotor dynamic balance inspection. For the quality of car paint, you can choose hundred-grid test, salt spray test and paint layer inspection.
The above repair process of aluminum alloy profile wheel hub is for reference only, and actually depends on the actual wheel hub damage.
