Spot welding is firm and smooth, and does not weld through two layers
Welding | Spot welding is firm and smooth, and does not weld through two layers |
Winding | winding is tight, the start and end of the sheet can not be turned up |
Planeness | surface unevenness is less than 0.1mm |
Fineness | No crystalline fine particles (no crystalline fine particles on the cut surface) |
Cut face | No obvious crack on the cutting face (no light transmission and peeling between layers) |
Surface | Visually without burrs, rust, or deformation (to control deformation within tolerances) |
Products | Do not contain Pb\Cd\Hg\Cr\PBBs\PBDEs |
