What welding is used for automotive aluminum alloy wheels?

1. Automotive aluminum alloy wheels have argon arc welding, electric welding, and gas welding. The welding effect of these welding methods is that argon arc welding is better than electric welding, and electric welding is better than gas welding.

2. The WSME315B aluminum welding machine is selected for argon arc welding, and 5183 high-strength aluminum welding wire is used. Before welding, all defective parts of the wheel hub need to be cleaned and then welded.

3. If it is electric welding, DC argon arc welding is required. Try to use a higher power, such as a 315 or higher DC welding machine, and use reverse welding. Welding rods can be welded using WEELDING555 aluminum welding rods suitable for wheel welding.

4. Gas welding is not used under the first two welding conditions. But this welding method has many problems and relatively poor quality. Because the wheel hub size is relatively large, heating it up is very troublesome. Even if heated, it can easily cause welding deformation. And the welding strength is also poor, which poses risks after repair.
