What kind of scratches will be encountered during CNC machining and welding of aluminum cavity?

With the increasingly fierce market competition, customers have higher and higher requirements for the quality of our products. In order to ensure the quality of the products, we must avoid the scratches during the welding process when operating the aluminum cavity CNC processing. What should we do? ?

1. Before CNC machining and welding of the aluminum cavity, it is necessary to remove the maintenance film on the front and back sides of the welding area to prevent the maintenance film from being burnt and causing poor appearance.

2. It is forbidden to touch the surface of the workpiece and the work surface directly (the grounding part can be handled separately), and it can be separated and placed with smooth wooden blocks, wooden squares, EPE, etc. Prevent iron filings on the work surface. The welding slag scratches the workpiece.

3. During the operation, it is necessary to handle with care, do not drag or pull, and do not place the workpiece on the work surface, pallet or the ground at will.

4. Welding joints should not be polished as much as possible. If polishing is necessary, the polished area should be reduced as much as possible.

5. The unwelded parts should be prevented from grinding as much as possible, and the welding slag splashing on these surfaces can be gently scraped off with a knife. If necessary, maintain and block the splash zone.

6. It is forbidden to bump or touch each other when placing materials. It is necessary to select maintenance devices for storage and turnover.
