2205 dual phase steel: S31803, F51, 1.4462; Material brand: 2205 duplex steel, American brand: UNS S31803, German brand: 1.4462, Chinese brand: 00Cr22Ni5Mo3N, F51, S32205;

Manual argon arc welding (mtig) or CO2 welding method and manual electrode welding can be used.Manual argon arc welding: select welding wire, 2.5 thick or 3.2 thick; For 6mm thick plate, x-groove can be used. Pay attention to welding deformation during butt welding, one on the front and one on the back to offset the impact of welding deformation as much as possible

When processing various stainless steel plate products, the surface of stainless steel needs to be processed first. Affected by many factors, there may be some problems on its surface, such as weld defects and scratches. Poor polishing effect is also easy to cause poor stainless steel surface.

Some iron will rust, so will stainless steel plates rust? Will stainless steel plates rust under wind and rain conditions? Stainless steel pipes have powerful functions such as a smooth and beautiful appearance, easy cleaning, and corrosion resistance, so their application range is quite extensive in the construction and decoration industry.

Repair welding method of stainless steel pipe:
1. Use welding data corresponding to the chemical composition of parent material;
2. Low current and fast welding are adopted to reduce heat and thermal deformation. During manual arc welding, short arc shall be used as
