How is the aluminum plate prepared before welding?

Answer 1

Before welding, the aluminum plate is typically cleaned to remove any contaminants such as oil, grease, or oxidation. This is often done using a solvent or a dedicated cleaner followed by a mechanical cleaning method like sanding or grinding to ensure a smooth surface. Edges may also be beveled or shaped to facilitate better weld penetration. Finally, the plates should be clamped securely in place to prevent movement during the welding process.
