Defects that may occur during processing:
The following points should be paid attention to when processing: (1) Dust and floating iron powder are embedded in the surface of the material; (2) Rough grinding and surface roughness will cause corrosion and deposition; (3) When the welding machine strikes an arc on the surface of the thin plate, the protective film is destroyed; (4) Grease paint marks the residual adhesive.
