Will the scratches during welding cause the stainless steel plate to rust?

During the welding process of the stainless steel plate, the surface damage will be caused by the grinding and machining of the welding, and the pollution of foreign objects will easily corrode the stainless steel pipe, which greatly reduces the corrosion resistance of the stainless steel product.

How to improve the service life and anti-corrosion ability of stainless steel pipes?
   Regularly remove rust on stainless steel pipes. However, there are many reasons why stainless steel pipes are corroded, and the treatment methods are different
   One of the scratches on the surface of the stainless steel pipe is that the welder strikes the arc on the surface of the stainless steel pipe, which leads to the destruction of the protective film on the surface of the stainless steel pipe, and the potential corrosion material is left on it, resulting in the corrosion of the stainless steel pipe.
   In this case, the corroded stainless steel pipe can be mechanically cleaned after welding (solder spot polishing and grinding) or repaired for welding defects. In addition, the rough surface of the stainless steel pipe must be repaired or re-welded. The scratched part can clean the stainless steel pipe to avoid the product or process lubricating oil remaining in the scratches of the stainless steel pipe to corrode the surface of the stainless steel pipe.
