11 Practices Make the Outer Surface of the Stainless Steel Electric Box More Beautiful

1. Select 30L stainless steel

30L stainless steel material is selected, which has the same performance as 304 stainless steel in all aspects (304 material has excellent performance in all aspects, is suitable for widely used materials in various places, and most people know its performance).

Compared with 304, 304L has better anti intergranular corrosion effect and can effectively solve the problem of welding rust;

2. Clean the oil and dirt at the welding position before welding; (passivation treatment before welding)

3. 316L welding wire is selected for welding.

This type of welding wire is a material with good low-carbon corrosion prevention effect, which is described in the introduction of 316L material above;

4. During full welding, try to use low current welding to prevent precipitation of high-temperature carbides.

For 1-2mm thick materials, the current shall be controlled within 45 ~ 75A;

5. During welding, pores are not allowed in the molten slag; No joint is allowed during full welding;

6. Prevent free iron from adsorbing the product surface during grinding, select another grinding site (separate from the grinding place of iron parts), and use new grinding wheel / polishing wheel (or grinding wheel / polishing wheel specially for stainless steel products) to polish / polish the product;

7. The welding spots (burn color) at each position must be removed.

The positions that cannot be polished inside can be wiped off with welding spot cleaning paste / cleaning solution

8. After grinding the welding slag, it must be polished after rough polishing, and no obvious trachoma, deep scratch, grinding mark and other rough surfaces are allowed;

(it is best to throw out bright light before wire drawing, which can play a good role in the appearance effect of cabinet after wire drawing.)

9. 120# of filament nylon wheel shall be used for wire drawing, and shallow wire drawing shall be carried out according to the vertical direction of the cabinet.

There will be no obvious silk texture and hand feeling when touching with hands;

[Effect of shallow wire drawing: the wire drawing pattern gives obvious visual effect and covers the shallow scratches;

There will be no obvious hand feeling when touching by hand, which can reduce the surface roughness and reduce the probability of surface darkening and corrosion (the reasons are mentioned above);

Longitudinal wire drawing can reduce the adhesion of dust and dirt on the product surface; shallow wire drawing can maintain the bright color before wire drawing]

10. Clean the dust and dirt on the product surface;

11. Wiping “talc powder” on the outer surface of the product can enhance the color and luster of the surface and partially protect it.
