If you are going to repair alloy wheels made of light metals or buy repaired, it is useful for you to familiarize yourself with the material of this article.
Disks can be repaired using argon -drunk welding and welding inverter, by raising, rolling, tapping. Consider each method in more detail.
Argonoduga welding. This is an electric arc welding among neutral gas – Argon. This repair method is used when it is necessary to brew a crack on the disk or to weld a disk fragment that has broken off from the blow. After such a repair, the disk almost always acquires its original appearance, but the structure of the metal is disturbed. The equipment that most car services have is not able to restore the original structure of the disk material. Therefore, the factory operational characteristics can not be restored. Casting process and welding process are completely different technological processes. When welding, local heating of the disk section occurs, and, therefore, a violation of the structure of the material in this place. Therefore, the risk of cracks in the welding area or even breakdown of the disk during its operation increases. This type of repair is the most dangerous. It is better not to buy renovated discs using argon -driving welding and not instruct the service to repair your discs in this way.
Richtovka. This is a rolling of a disc with preliminary heating. This repair method is used for steel discs. When heating cast metal disks, its structure is the same violated. After the repair, the discs are no different from the new. Especially if you paint it after the repair. This repair method is not as dangerous as the previous one, but the same is not desirable. Factory characteristics of renovated discs are not restored.
Rolling. This is a drive roll without preliminary heating. The structure of the material will not change with this repair. The disadvantages of the method are that serious damage cannot be eliminated, the repair is spent more time than in the first two cases. The wheels repaired in this way do not pose any danger during operation.
Percussion. This is a manual disk editing method. Requires large time costs, will not allow in most cases to completely restore the appearance. However, this method is quite widespread. Disks repaired by tapping during operation are not dangerous.
