How to extend the using time of the stainless steel welded wire mesh?

There are many ways to extend the using time of the stainless steel welded mesh, here let us share you one way during production.

Cleaning and pickling passivation of stainless steel welded wire mesh before and after welding.

Since grease is a source of hydrogen, pores will be formed in welds where the grease is not removed, and low melting point metal contamination (such as zinc-rich paint) will cause cracks after welding. Therefore, the surface of the wire must be cleaned before stainless steel welding. Grease can be used Acetone scrub, paint rust should be removed with emery cloth or stainless steel wire brush, and then wipe with acetone.

No matter what kind of welding technology is used in the manufacture of stainless steel welded wire mesh, it must be cleaned after welding. All welding slag, spatter, stains and oxidation color must be removed. The removal methods include mechanical cleaning and chemical cleaning. Mechanical cleaning includes grinding, polishing and sandblasting, etc. Carbon steel brushes should be avoided to prevent surface rust. In order to obtain the best corrosion resistance, it can be immersed in a mixture of HNO3 and HF, or pickled passivation paste can be used. So as to ensure the use of stainless steel welded wire mesh for a long time.
